A Bluetooth Device As Parental Support

Once you have children, your life seems to skip from one set of worries to another. You begin by reading all the baby books and worrying about whether it's safer to lay an infant down on its stomach or its back. Once they hit the crawling stage, you start covering all the outlets and keeping your floor cleaner than ever before. Next you worry about streets and strangers, keeping your toddler within sight and teaching him or her not to dash in front of cars or wander away from you at the store.
Then they start school, and your worries change. You worry about their teachers, about bullies, about learning and receiving acceptance. You discover, to your dismay, that you can't control all their influences or guarantee smooth sailing. However, if you've been strong and consistent through their early years, you start to lighten up as you watch them make good decisions on their own.

And then they become teenagers. Whooee! You no longer have the luxury of keeping them in sight all the time, much less of knowing that they will follow all your rules once out of your sight. Just when you thought you could relax a little, they start driving! Possibly the only saving grace is the advantage that technology gives us. Having spent a few frightening hours during my own teenage years, stranded with a flat tire or an empty tank, I'm awfully grateful for cell phones. They give parents more options for reaching their children, and teens fewer excuses for being out of touch. I've tried to be a good example, too, making sure I use a handsfree car kit myself, since I expect them not to be distracted by dialing or holding a phone while they're supposed to be paying attention to the road. In fact, as each of my sons has arrived at that magical 16th birthday, I've given him his own Bluetooth device with strict instructions to use it at all times in the car. Again, I can't be certain that they follow my rules once out of sight, but I can at least take away their excuses.

Now if only the state legislature will outlaw texting while driving, I can relax a little bit more. It always helps to support my position when traffic cops potentially are out there watching, too!

Bluetooth Peripheral Device Drivers - What to Expect When Updating

Updating Bluetooth peripheral device drivers isn't overly difficult. However, you may run into a few problems. These problems are not monumental, especially if you are prepared for them. Among the two most important preparation steps are: setting System Restore points and rebooting.
First, any time you update Bluetooth peripheral device drivers, or any device driver, there's always a chance that something could go wrong. It may be an honest mistake in choosing the wrong set of Bluetooth peripheral device drivers for your operating system or it could be a problem with the drivers themselves. Your new drivers could be corrupt or the manufacturer could have made a mistake. No matter what happens, if you have a restore point, you can quickly recover.

To set a System Restore point, you'll need to go into System Protection and create one. In Windows Vista and Windows 7, go to Start and type "create a restore point" into the Search bar. Click the link that matches. Click Create and confirm your choice when prompted. Now, you can safely update the Bluetooth drivers. Should a problem occur, you have the peace of mind of knowing that you can rollback your system to its earlier state. Once rolled back, you'll have your original Bluetooth peripheral device drivers. To recover using the System Restore point, go to Start > Programs > Accessories > System > System Restore and follow the prompts.
Rebooting may seem like a silly solution to a problem with newly installed Bluetooth peripheral device drivers, but it's often the key. Many driver updates require a reboot before the operating system fully understands how to work with the device. Even if you've installed new Bluetooth drivers and have not been prompted to reboot, go ahead and do it. It only takes a few minutes to reboot and you could potentially save yourself a big headache by doing so.
Once your Bluetooth drivers have been installed and your system rebooted, test your Bluetooth device to make sure that it functions as expected. If so, the update is a success - at least for now. You'll want to keep an eye on how your computer, its software, and other devices respond after you've updated the Bluetooth drivers. Any time you introduce new hardware, software, or device drivers, there's always a chance that a new conflict has been introduced. If you notice any odd behavior in the days immediately following, consider the possibility that the Bluetooth peripheral drivers may be involved. If so, you can revert to your old restore point and see if the problem goes away. Hopefully, the update will go smoothly as most do and you won't need to revisit the old restore points.

Bluetooth Health Data Profile (HDP) and the Android 4.0 OS

Imagine you are a physician and have a patient with a heart condition. The patient is currently at a friend's house and is experiencing issues. Your Android phone alerts you of the potential problem. You open the alert and are able to see in real-time your patient's heart rate, blood pressure, blood oxygen levels and other vital statistics that will help you determine next steps. You decide that your patient is in distress and send for an ambulance with the touch of a button and immediately call your patient. Your patient's location is also known because of the GPS in their smartphone.
This scenario is quickly becoming a reality with a recent development in technology: Bluetooth Health Data Profile (HDP). Bluetooth HDP is a new layer on top of the Bluetooth protocol stack that specifies a standard set of instructions for medical devices. The Bluetooth HDP device securely connects and transmits data to a smartphone or other receiver. The data can then be transmitted to a central health management application used by the physicians, nurses, home care providers, etc.

It is true there are thousands of medical devices that are currently Bluetooth enabled. However, until now there has not been a standard set of instructions to exchange data. This means that each device must have its own proprietary application to communicate with. Bluetooth HDP devices will be able to communicate with applications developed to support the new standard. One huge benefit to consumers is that we can buy a heart monitor from one vendor and a blood oxygen meter from another. Both of these devices can now communicate with your health care providers chosen health management system. This is good for the consumer because it give us choice and does not lock us into a single vendor's solution. We are also able to pick the best of breed hardware and software as well as purchase at competitive prices.
Why do we need a standard set of instructions? Imagine if the web did not use a standard set of protocols and technology to present web pages? This would mean that you would need a specific browser to view a website built with technology X and another for one built with technology Y. One web browser, like Firefox, may or may not work with every website. Because of these standards we can use one browser to surf the web.
Medical device manufacturers and health management software developers will be the largest consumers of this technology. Because we have a growing aging population, healthcare providers need to figure out better ways to provide quality care to their customers and scale with the increasing number of cases. However, there are others that can also take advantage of this technology. For example, cardio equipment manufactures could use Bluetooth HDP to receive data from a heart monitor worn by the user and send it to the treadmill they are running on. The speed of the treadmill could be increased or decreased based on data received from the heart monitor and according to the workout type. The heart monitor could also be used on any other treadmill at any other gym as long as it is a Bluetooth HDP enabled piece of equipment.

The possibilities are endless for the implementation of Bluetooth HDP. Creative individuals and groups will of course push this technology to the limits.

Difference Between Bluetooth Stereo Headphones and Bluetooth Stereo Headsets and Features

In general perception, it's not really a big of a difference but some manufacturers use this differently on each product name, its useful and information to know the key difference between a blue stereo headset and headphones. Following are the key points which actually sets them apart.
Earpiece Placement
Head phones are generally covers the entire ear with a speaker to deliver quality sound, whereas in the case of Headsets, the speaker usually sits outside of the ear.
Speaker Configuration
Headphones are normally equipped with two speakers (binaural) which cover both the ear and Headsets are usually have only one speaker (monaural), covering only one ear. These are now latest and of the all time best Bluetooth Stereo headsets which have two speakers, which means the "Bluetooth stereo headset" is now equivalent to "Bluetooth head phones"

Applications
The Bluetooth application was considered to be the basic difference between Bluetooth headsets and Bluetooth head phones I its "Application" but now a lot of these Bluetooth devices offers exactly the same functions, however the classical difference is still there with some of the manufactures. While Bluetooth stereo head phone encourages stereo music but they probably will not support hands free communication with your mobile phone device (Most new Bluetooth stereo headphones do support hands free communication).
The Bluetooth stereo headsets allow users with the ability to listen to your favorite music and provide hands free mobile communication. Stereo Bluetooth headset automatically switches between cell phone call and music so one don't have to manually switch between Bluetooth features for availing both the features if music and phone call. It works in a way that when a phone call comes in, the headset notifies you - mostly with a sound beep, after the conversation has ended and the phone disconnects and the music will automatically resume.
Basic Feature of Bluetooth headsets and headphones
Most Bluetooth devices offer a range of up to 30 ft but some of the newer models, using the latest Bluetooth3.0 technology are now able to provide over 60 ft.The device average weigh is about 100 grams and easily sits inside ear to prove 15 to 17 hours of talk time and app 500 hours standby time. The latest Bluetooth hands free consumes less power and can provide unbelievable talk time of about 12 hours.

The convenience of wireless Bluetooth stereo audio is incredible as you don't have an annoying wire dangling around your neck. One can walk around home with Bluetooth stereo headphones / headsets and don't have to worry about carrying MP3 player or iPod. Now the latest electronic products including laptop, PC, TV, DVD player, home stereo, or MP3 player are equip with Bluetooth interface to wirelessly stream sound.

Understanding the Apple MacBook and Bluetooth Connectivity

You should know whether your MacBook supports Bluetooth connections. However, latest Apple laptops have internal Bluetooth component. If you're using an earlier Mac laptop without built in Bluetooth, though, you're certainly out of the Bluetooth loop. Even so, you don't have to pitch your faithful Mac if it doesn't yet communicate to other Bluetooth-enabled devices! You can add Bluetooth feature to your Macbook with a widely available USB Bluetooth adapter. A regular Bluetooth adapter sells online for approximately $30.
Your external Bluetooth adapter should have automatic data encryption capability, which can protect your Macbook if there's a Bluetooth cracker within about thirty to sixty feet of your Macbook. The adaptor may link with up to eight other Bluetooth devices as the same time. (Come to think of it, if there are a lot of people within 60 feet of your MacBook Pro during a LAN party bash, you'll guess this feature really is important!) You'd expect any modern and high-tech operating systems like Mac OS X should come with basic Bluetooth supports. You'd be right; however Apple goes one step further.
Your Macbook comes with System Preferences and utility software to help you get your Macbook connected with nearby Bluetooth devices.
Choose the System Preferences icon located in the Dock. With the Bluetooth pane, you can
* Create new Bluetooth devices. Just click the 'Set Up New Device' to open the Bluetooth Setup Assistant utility, which sets up other Bluetooth devices for connection with Leopard. Read the onscreen instructions to configure a number of common Bluetooth gadgets (including mice, cellphones, keyboards, and printers), or you can also choose Other, Setup Assistant will looks for other Bluetooth devices and adjust the settings so that those devices are ready to party with your MacBook. Be sure that Bluetooth devices are discoverable and in range (available for connection with your Macbook) before you open the Bluetooth Setup Assistant utility. Read your user manual to understand how to set a Bluetooth device as "discoverable", the device should be about twenty feet away (or less) from your laptop.
* Set up Bluetooth connections. Choose the Advanced button to establish, remove, enable, or disable a Bluetooth connection, using a Bluetooth connection as virtual serial port (for the simple file transfer) or as virtual modem (for bidirectional transfer, including using Internet connection through a Bluetooth cellphone).

You may also specify if a Bluetooth port should be encrypted.
It is recommended that you activate the Show Bluetooth Status located in the Menu Bar check box. Luckily, the Bluetooth menu allows you to conserve power by disabling your Bluetooth feature until you need it. It is quite convenient to toggle your Macbook's discovery status and also configure a device or send a file. It's also easy to know which devices are connected to your Macbook.
If you won't be connected with Bluetooth devices while you are on the road, disactivating a Bluetooth service on a Macbook will help save battery power. There is another handy Bluetooth resource, the Bluetooth File Exchange. You have to launch Bluetooth File Exchange the old-fashioned way; just go to your Utilities folder, inside the Applications folder. It's quite similar to a traditional file transfer protocol (FTP) application, choose the Bluetooth File Exchange icon to go to the file selection dialog; then browse the file you want to send to a connected Bluetooth device. You can also choose to browse the file in other networked Bluetooth device so that you know what the user of that device is offering.
You may also configure your default settings for file exchange in the Sharing pane, which is located in the System Preferences. Just click the Sharing icon and then choose the Bluetooth Sharing check-box to display the setting parameters. Here you can manage what Leopard does when you get files or PIM (Personal Information Manager) data with Bluetooth File Exchange. For example, with this setting, Leopard can
Ask you for permission to receive a file or Personal Information Manager item
* Accept any files and PIM items without any prompting or restriction
* Keep all incoming items and files to a specified folder
* Restrict file-sharing only for the items and files in the specified folder when other Bluetooth devices browse your MacBook.
It is recommended that you use these default setting in Leopard for file exchange:
* You know when someone's sending you something.
* Anything you receive will be saved in your Downloads folder.
* If you turn on the File Transfer, you can allow others to see the content of your Public folder.

Step Up to Bluetooth For 2 Way Radios

Simply put, Bluetooth is a type of technology that allows information to be exchanged between two or more capable devices without the use of cables or wired connections. It is common these days on cell phones where the caller simply uses a small earpiece/microphone combination to allow them hands-free communication through the phone. This saves having to hold the phone all the time during the conversation, plus it allows the wearer to get up and move about freely or even keep typing, driving or working without interruption. Another great way to utilize this technology is Bluetooth for 2 way radios.
Many of the new systems have a great deal of range, allowing the wearer to move a fair distance away from the radio and still receive the signal. This is important for a variety of reasons since it frees up the user and prevents a lot of the restrictions of movements when using a traditional system. They can be left in safe places and often last much longer since they aren't carried about as much. Many motorcycle owners might be interested in this type of device, due to it's ease of usability.
The technology works through a very small, relatively inexpensive computer chip that is added to any type of electronic system. Since the frequency used is different than other types of radio frequencies there is no interference, plus the devices are synchronized to only respond to each other. This means that the system only hears signals from those devices you have linked, just like your cell phone only sends to your earpiece, not to any other receivers. It also means that your device won't interfere with other wireless systems or even other Bluetooth devices you may be operating.
Bluetooth adds even more features for those individuals that want to have full and complete hands-free use while still getting crystal clear sound quality. Different companies have had the option of push to talk on their existing radio systems, however the quality of sound as well as the hand held component of the system has made them bulky and less than perfect in the past. This technology has reduced wires and total freedom is possible. What more could a person want?

The newest, sleekest and smallest systems are very easy to use. The earpieces, which contain a very small microphone boom, are much shorter and thinner than traditional earpiece/microphone headsets. The systems work on chargers, with the earpiece/microphone and the receiving/sending unit all charging on the same system. To sync up the system it is as simple as pressing and holding down a button simultaneously on both pieces, forming the connection. Once the link has been established the first time there is no need to do it again. Many of the systems also have optional push to talk buttons that can be mounted anywhere that is easy to reach. This eliminates the need to have to touch the radio itself to talk or answer a call.
The whole Bluetooth system simply plugs into your set, turning anything that has compatibility into a fully functioning wireless device. This literally adds to the value of the device as you no longer have to hold it, push the specific buttons and struggle to hear what is going on. The Bluetooth for 2 way radios will eliminate a great deal of the environmental noise since the sound from the device is going directly to the earpiece, transferred wirelessly. Sound is clearer and free from distortion, plus volume controls on the earpiece mean you can adjust the sound to suit your particular needs.

Bluetooth on PC - What's a Bluetooth Adapter Dongle?

A Bluetooth adapter dongle is a USB accessory for your PC or Notebook which enables you to add Bluetooth wireless capability to your computer device. The dongle usually has a standard USB (Universal Serial Bus) Type-A rectangular connector which plugs into any spare USB receptacle on your device and provides power to the dongle as well as transferring the data picked up by the wireless dongle.
The beauty of a Bluetooth adapter dongle is in the fact that it can be installed on a PC or Notebook in a matter of minutes and can be de-installed just as quickly and re-used on another machine if necessary. Some adapters come with the installation software already loaded on the dongle for automatic installation, whereas some dongles also known as Bluetooth USB Adapters will come with an installation CD to enable the loading of drivers and associated software quickly and efficiently.
Once installed, your Bluetooth USB Adapter is ready to synchronise with Bluetooth enabled devices such as keyboards, mobile phones, video games controllers and other PCs if necessary.
So what is Bluetooth?
Bluetooth is a wireless technology designed for short range communications in the ISM (Industrial, Scientific and Medical) bands on frequencies in the range 2400 - 2480 Mhz. A Bluetooth network is often known as a PAN (Personal Area Network) to differentiate from a LAN (Local Area Network) or WAN (Wide Area Network). It is so called because it is designed to connect devices wirelessly over a very small range of only a few metres. The Telecommunications giant, Ericsson first developed this Open Standard in 1994 and it is now managed by the Bluetooth Special Interest Group.

A network of devices using this wireless technology will have a single master device which can communicate with up to 7 other devices in the network known as a piconet. Normally the device that initiates a connection to another devices will initially assume the role of the master device, with the other device automatically becoming the slave device. A master will communicate with other slave devices in the piconet in a round robin fashion if there is more than one slave. Versions of the Bluetooth specification have evolved since the first specification in 1994, with the latest specification being version 4.0 has data rates up to 25 Mbps. Contrast the early version 1.2 which only had a data rate of 721 Kb;ps.
Most Bluetooth Adapter Dongles on the market today either support the version 2.0 or 3.0 standards, with version 3.0 and enhanced version 4.0 being backward compatible with versions 1.2, 2.0 and 2.1. This means if you purchase a version 3 dongle, it should be able to synchronise and connect with older peripherals using earlier versions.

How to Connect Your iPad With a Bluetooth Headset

Your iPad is configured to utilize a wireless technology called Bluetooth, which enables you to make wireless connections to other Bluetooth compatible devices. Most laptop computers come with Bluetooth built in to the system as well as most cell phones. The Bluetooth device allows your iPad to connect with any Bluetooth compatible device such as keyboard or mouse, cell phone, digital camera, printer, headset etc. Bluetooth technology is for short range use therefore 33 feet is the maximum distance two Bluetooth devices should be apart from each other.
Configuring and connecting any two Bluetooth devices is very simple and can be broken into two distinct phases: Discoverable and Pairing.
Bluetooth devices only broadcast their availability when you want them to. This is called making your device "discoverable". For privacy and functionality, many Bluetooth devices need to be paired with another device before the connection is established. "Pairing" or "to pair" or "paired" is simply the technical language on making a permanent connection between two Bluetooth devices. This is useful because once two devices are paired; you never have to configure the devices again. Just turn them on and two devices will automatically connect to each other even in a room full of other Bluetooth devices. All Bluetooth devices can be "un-paired," meaning you can break the connection and pair with another Bluetooth device.
To Pair a device, you must first make it discoverable, connect to the device of your choosing, and enter a multi-digit (usually four) pass code or PIN. Pairing devices such as your cell phone with your iPad will allow you to choose a unique pass code. For other devices such as Bluetooth headset, the headset comes with a default passkey that you enter in your iPad during the pairing process. (Notes: Even though most headsets default passkey is 0000, your connection will be secure with your iPad.)
How to connect your iPad with a Bluetooth headset

Bluetooth Low Energy - A New Revolution in Connectivity

What is Bluetooth Low Energy?
Bluetooth Low Energy is pretty much what it says on the tin. It is a new Bluetooth protocol that is built on the standard Bluetooth protocol but uses incredibly small amounts of electrical energy; so little in fact that a device will be able to operate for a full year using only one tiny button cell.
How long has it been around?
Although the very first of these chips to be manufactured appeared in April 2009, the concept has been around for a couple of years and it has been called different things. When the Bluetooth Special Interest Group (SIG) first came up with the concept it was called Wibree. Later it was renamed as Ultra Low Power (ULP) Bluetooth Technology, and it acquired its current name in 2009.
How will it be used?
Bluetooth Low Energy is the next evolution of Bluetooth and it is designed to transfer data between two devices extremely efficiently and using only a minimal amount of electrical energy. How this will work is best explained by an example.
Imagine that you are wearing a sportswatch that monitors your heart rate and your blood pressure continually whilst you are out on a training run. Without you taking any action, your sportswatch will be able to transfer this data to your phone using Bluetooth Low Energy, and your phone will be able to transmit this data over the internet directly to your website so that you can analyse it later or so that your coach to can examine it in real time.
This is just one example and naturally there are a great many other potential applications. We will outline some more later in this article and we will describe them in depth in future articles.
Evolutionary or Revolutionary - which one is it?
So far we have referred to this new technology as revolutionary and evolutionary. This is not an error or an attempt to confuse our readers. In fact the technology is both. It is evolutionary in that it builds on conventional Bluetooth technology and extends the design experience that has been gained already, and it is revolutionary in that the new Bluetooth Low Energy protocol has been designed from scratch or, as the engineers like to say, from the bottom up. It is also revolutionary in what it will enable Bluetooth to achieve in terms of new applications and devices.
How much will it cost?
Developing this new technology over the last couple of years has not been cheap. In fact a huge amount of design work has been carried out between the initial concept and the first silicon chips, and consequently the manufacturers intend to recoup this expenditure from selling devices.
On the other hand, one of the beauties of Bluetooth Low Energy is that it is very cheap. In devices such as mobile phones, Bluetooth low energy will sit alongside conventional Bluetooth (dual mode devices); in fact they will use just a single chip and its cost will be no more than in conventional Bluetooth. Naturally in devices that just use Bluetooth Low Energy the chips will have a net cost, but this will be very low.

What new gadgets will use Bluetooth Low Energy?
We have already given one example of how data collected from a sportswatch may be transmitted directly to the internet via your mobile phone. Bluetooth low energy may be used in many other sports applications such as smart training shoes, sensors on a bicycle or a canoe, even in a bat, racket or golf club. Whatever sport you might be involved in, Bluetooth Low Energy will allow you to monitor your performance in real time and transmit it directly over the internet.
Other gadgets that are related to the above are in the field of healthcare. For instance someone with diabetes could use Bluetooth Low Energy gadgets to constantly monitor their blood sugar levels and the data could be transmitted directly to that person's doctor or physician; heart data could be monitored for any anomalies; the health of elderly people could be monitored remotely.
Of course there are many other applications not involving health and fitness. For instance it will be used in remote control, in household appliances and in entertainment systems. What is certain is that hundreds or even thousands of new applications will emerge over the next few years.
How will it change my life?
It is inevitable that the low cost low energy connectivity offered by Bluetooth Low Energy will be life changing. With conventional Bluetooth your Personal Area Network (PAN) is restricted to a handful of devices such as your mobile phone, your laptop and computer, your MP3 player, a Bluetooth Headset, Bluetooth Headphones, your GPS and possibly your car. With Bluetooth Low Energy your PAN will be extended massively to include wearable gadgets, accessories, white goods in your home, lights and curtains, sensors and intruder alarms, remote controls for all your entertainment systems and all the other functions that we have mentioned; the possibilities are huge and limited only by your imagination.
What is the timeline?
As we have said, the first chips have been made by semiconductor companies and are being evaluated by gadget manufacturers. This exercise will take several months to complete and there might be some further design iterations before everything is finalised, but it will not be long before the first Bluetooth Low Energy gadgets and phones appear on the market. Before too long, all new Smartphones will incorporate dual mode Bluetooth Low Energy. Industry analysts estimate that by 2014 the consumption of Bluetooth chipsets incorporating Bluetooth Low Energy will have reached two billion a year.
Final Word
Bluetooth Low Energy is on its way and it will be a life changing technology that will permit a revolutionary increase in the level of connectivity that can be achieved between a new generation of devices, conventional Bluetooth devices and the internet. In future articles we will look in some detail at the technologies involved, at new applications, and any competitive solutions that might also be on the horizon.

Bluetooth Basics - Bluetooth Technology Tutorial

Bluetooth Basics
Bluetooth technology is nothing new, but in many respects it still seems to be more of a buzz word rather than a well understood, commonly accepted technology. You see advertisements for Bluetooth enabled cell phones, PDAs, and laptops, and a search of the Geeks.com website shows all sorts of different devices taking advantage of this wireless standard. But, what is it?
History
Before getting into the technology, the word Bluetooth is intriguing all on its own, and deserves a look. The term is far less high tech than you might imagine, and finds its roots in European history. The King of Denmark from 940 to 981 was renowned for his ability to help people communicate, his name (in English)... Harald Bluetooth. Perhaps a bit obscure, but the reference is appropriate for a wireless communications standard.
Another item worth investigating is the Bluetooth logo. Based on characters from the runic alphabet (used in ancient Denmark), it was chosen as it appears to be the combination of the English letter B and an asterisk.
Capabilities
The FAQ on the Bluetooth.org  website offers a basic definition: "Bluetooth wireless technology is a worldwide specification for a small-form factor, low-cost radio solution that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet."
Just like 802.11 b/g wireless networking systems and many cordless telephones, Bluetooth devices operate on 2.4 GHz radio signals. That band seems to be getting a bit crowded, and interference between devices may be difficult to avoid. Telephones are now being offered on the 5.8 GHz band to help remedy this, and Bluetooth has taken its own steps to reduce interference and improve transmission quality. Version 1.1 of the Bluetooth standard greatly reduces interference issues, but requires completely different hardware from the original 1.0C standard, thus eliminating any chance of backwards compatibility.
The typical specifications of Bluetooth indicate a maximum transfer rate of 723 kbps and a range of 20-100 meters (65 to 328 feet - depending on the class of the device). This speed is a fraction of that offered by 802.11 b or g wireless standards, so it is obvious that Bluetooth doesn't pose a threat to replace your wireless network. Although it is very similar to 802.11 in many ways, Bluetooth was never intended to be a networking standard, but does have many practical applications.

Practical Applications
There are a variety of products that take advantage of Bluetooth's capabilities, from laptops and PDAs, to headphones and input devices, and even wireless printer adapters.
Many Laptops include an onboard Bluetooth adaptor to allow the system to connect to any Bluetooth device right out of the box. For laptop or desktop systems that do not have an adaptor built in, there are many USB Bluetooth adaptors available.
Bluetooth enabled PDAs allow for convenient wireless synchronization and data transfer.
Headphones can take advantage of Bluetooth for two purposes... audio playback and mobile phone communications. Using something a mobile headset with a Bluetooth enabled mobile phone allows anyone to go hands free, as well as wire free.
Logitech, and other manufacturers, also produce input devices that eliminate wires thanks to Bluetooth. You can add a Bluetooth mouse to your system, or both a mouse and keyboard. One advantage that Bluetooth wireless keyboard/mouse combinations have over the standard RF wireless keyboard/mouse combinations is range. Where most standard RF keyboard/mouse combinations have a range up to 6 feet; a Bluetooth keyboard/mouse combination will usually have a range of up to 30 feet.
Bluetooth printer adaptors make sharing a printer extremely convenient by eliminating the need for any wires or special configurations on a typical network. Printing to any compatible HP printer from a PC, PDA or mobile phone can now be done easily from anywhere in the office.

Bluetooth Security and The BlueSnarfing Blues

What is "BlueSnarfing?" BlueSnarfing is the identification of Bluetooth devices in "discoverable" mode in order to connect and steal personal data such as: photos, SMS messages, phonebook contacts or the phone's IMEI. If you possess a vulnerable device and your Bluetooth is on and 'discoverable', anyone within 10 meters of you could potentially connect to your device and download its' data without your authorization using easy-to-use tools.
Bluetooth is a popular way to exchange data between enabled devices, commonly including mobiles phones, PDAs, laptops, etc. BlueSnarfing is a technique of abusing the Bluetooth "pairing" protocol, which is the essence of the technology that allows devices to recognise and authenticate each other in order to transmit data between them.
 
The technique is simple, more so than traditional systems Hacking, with the advances in telephony and PDA functionality and storage capability, the volume and targeting of BlueSnarfing attacks will increase and lead to far more serious compromises than Paris Hilton's address book.  
 
The following is a summary of the three most prominently recognised BlueSnarfing attack methodologies:
 
BACKDOOR: The Backdoor Attack is the method of establishing an unrecognized "trust relationship" between device "pairing" mechanisms. If the device is on default and does not require connectivity authorization, an attacker may make the connection undetected - unless of course the owner of the device is actually looking at the phone screen at the exact moment of the attack. Not only can an attacker retrieve data from the device through this attack, he can also access other services deployed on the device such as: modems or Internet connections, WAP and GPRS gateways without the owner's knowledge.

 
BLUEBUG: The Bluebug Attack is the technique of creating a serial profile connection to the device to commandeer the AT command protocol. Once access to the AT command set is obtained, it can be exploited by the use of easy to use freeware tools to control, to initiate, intercept or forward telephone calls and SMS' or connect to data services such as the Internet (and if this is accomplished theoretically, an attacker can theoretically listen in on your calls from anywhere in the world).  This attack for instance would allow an attacker to set up call diverts to 900 numbers or to impersonate the victim.
 
SNARF: The Snarfing Attack is the technique used to connect to a Bluetooth device without alerting its' owner to gain access to (and use of) restricted portions of its' stored data using freeware. This would include access to your: phone menu, call, configuration and security settings, profile, display, and ring tones, calendar and clock properties and settings. The attack also allows access to the phone IMEI number (the unique number which identifies your phone to its' network) and may be used to "clone" your number to make fraudulent calls.
 
BlueSnarfing is easily prevented and no reason for the blues, simple configuration changes can prevent the attacks reducing the costs of Penetration Testing or Ethical Hacking activities in this area to ensure your workforce or your personal device is secure.  Just keep in mind that behind every "convenience" is a potential vulnerability and never leave your phone (or any technology) on "default."

Infrared, Wireless, Or Bluetooth Headphones?

Infrared headphones, wireless headphones, and Bluetooth headphones. Each of these categories of headphones has a techie-sounding name, but at the bottom line of them all is just plain old wirelessness, which is what you basically thirst for in a cordless audio device.
Of the three, both wireless and Bluetooth headphones share a similar method of broadcasting and receiving the audio signals. Infrared headphones, on the other hand, operate on quite a different level. All three, technically, are wireless headphones, albeit using distinctive means for achieving the same purpose.
Wireless headphones, in a more restricted sense, are more accurately called radio frequency or RF headphones. Just like their Bluetooth counterparts, these headsets use wireless radio frequencies for sending audio signals from a transmitting device (i.e., a base station) to the headsets so that you can hear the sound. However, since many other devices (e.g., cordless telephones, remote-control cars, etc.) also use radio signals for proper operation, RF headphones tend to compete with such devices for pathways. Thus, it is not uncommon for signal interference to be experienced with RF headphones.
RF headphones remain popular these days owing to the wide applicability of radio frequency broadcast technology in many electronic products. Yet, in the light of Bluetooth technology, RF headphones appear simplistic. Bluetooth hasn't completely nudged radio frequency headphones off the grid, though. After all, both types use a similar medium for their signals (i.e., radio frequency). One striking difference between the two is that with Bluetooth headsets, no special transmitter base is required. All that you need are at least two Bluetooth-capable devices, which you need to bond or pair so that the devices can create a network between or among them. Having created a personal area network (PAN), the devices can share various types of data, including audio signal data.

Infrared headphones, on the other hand, make use of light. It uses not any ordinary kind of light, but the infrared kind. It is a form of electromagnetic radiation whose frequency is below that of the red frequency range in the color spectrum (thus, the name infrared). Infrared headphones work in a similar way to your television's remote control, except that the headset receives light signals from a transmitter and converts them to audio signals on your headset's speakers. The biggest downside of infrared headphones is their need to be always within the line of sight of the transmitter device, or else the connection is broken. On the up side, though, you won't need to worry about signal interference with infrared-powered headphones.
Infrared headphones, wireless headphones, and Bluetooth headphones all operate quite differently from one another, but they are quite capable of giving you quality audio in addition to freedom of movement.

Walkie Talkie Headset With Bluetooth Technology

The walkie talkie headset is a relatively new technology. It is actually a spin off of the more traditional handheld transceiver device, which has been a popular invention for many years. There are even battery operated children's walkie talk sets. Nevertheless, the most popular types today are ones that use software to turn existing mobile devices into hand held transceivers. These become even more convenient when blue tooth technology is added. When it is added, the mobile device becomes more like the traditional walkie communication devices.
What is most fascinating about using Bluetooth with a mobile device is it provides noise-cancellation features for clear communication. However, it also provides simultaneous linking between other non Bluetooth devices such as a PC using Skype. So now a person can chat with someone at their home as effortlessly as if they were right their in the room with them.

Probably the coolest feature though is when two of the same devices are linked together. The users can get instant two way communication within a 250 thousand square foot area. This immense range far surpasses the range of the older technology. Furthermore, plans are in the works to expand this technology so up to five users can be in the same push to talk loop. This will truly change the way many folks are communicating today.
Any company looking to save some money should consider this type of Bluetooth

Bluetooth Driver Problems Fix

Bluetooth technology has been increasingly welcome by people because it allows computers, phones and other devices to communicate with each other over short distances (up to 100 meters) in a quite fast speed. For example, pictures may be transferred from your blackberry 8520 to a PC or from a PC to your blackberry 8520 effortlessly via Bluetooth. However, if you want to connect your Bluetooth devices to a computer, you need to install a Bluetooth driver. And if your Bluetooth driver acts up, they would have some of the common problems as below:
1. You can not send files via Bluetooth.
2. You can not transfer pictures from your cellular phone to your computer and make hardcopies of them.
3. File transmissions are not complete and some transfers are even corrupted.
4. Your Bluetooth device reports that the transmission has been finished, but you can not find the files or you find them in a wrong device.
If your Bluetooth driver is outdated, inappropriate, missing or corrupted, problems above may occur, so you need to update or install the right Bluetooth driver.

To find out the available updated driver and update it from time to time or install the right one for your Bluetooth device may be a pain in your neck, because there are so many drivers on the Internet and the driver used on one type of computer may not work properly on another because of differences in hardware specifications and operating systems. Fortunately you can download a good PC Driver Helper to help you simplify your jobs; PC Driver Helper can identify and install the specific Bluetooth driver and other drivers for your computer to make the most out of your dongle automatically just with several clicks.

Problems Streaming Bluetooth From Your iPhone, Here's a Handy Workshop

There can be a number of connectivity problems with an iPod touch or iPhone and a vehicle's hands-free Bluetooth system. This is a workshop to see how to solve problems playing Bluetooth music through a connection with a Ford Microsoft Sync system.
From a review of online forums you can see that both Microsoft and Apple are pointing fingers at each other regarding why the connection to SYNC occasionally causes problems. Bluetooth "is what it is" - it's a low power short range way to connect computer devices wirelessly. Often the system can get out of phase and cause connection problems. Here's what you can do to set things back to normal...
While in your car with the radio on, go to the Phone Menu and select "System Settings" on a vehicle with the LED screen on the top of the center console. Later in this workshop, we'll go over how to do this process with a touch screen system. Turn the turning knob to select "Delete Device." Find your device by name and then press OK to delete the device. Now go to your iPhone. Go to the Settings icon, go to the General icon, then select the Bluetooth connectivity area. Delete "Sync" from your list of connected devices (tap on the blue arrow at the right, it takes you to another screen and then select "Forget Device." Then, power your phone completely off, or pull the battery for at least a minute, then replace the battery. Restart your phone.
Now turn off your vehicle. Open the hood. Loosen the bolt holding the black battery cable clamp assembly and remove it from the battery for about two minutes or more. Then replace it and retighten the clamp. Close the hood.
Return to your vehicle and start it up. Let the vehicle run for at least four or five minutes. This reboots the electrical systems from factory specs. Your radio may default back to the AM band and you may need to reset your clock time. Turn your vehicle off again and open the door (this completely powers down the vehicle). Start the vehicle back up.
Now go to the Phone Menu on the center console, go to Bluetooth Devices, and select "Add Device." It will prompt you to press OK to begin Pairing a device. Go to your phone, to the Settings icon, select General, then Bluetooth Settings. Look for the "Handsfree" Button and let it become a "Sync" button. Touch this button and another screen appears asking for the 6-digit Pin that is being displayed on your center console. Enter that number and push "Pair" on your phone. Within a few seconds the Sync system will respond that it has connected. Be sure to activate the 911 Assist when prompted, push OK to set the phone as the Primary Phone and then OK to allow the phone book to download. It may take up to three minutes for the phone book to download.

Now when you push the "Voice" button on the steering wheel, you can say "Bluetooth Audio" to access your iPhone music (or go to the Pandora App, or other App, and turn it on). The music should start within a few seconds, if not, push the Voice button again and say "Play." If you push the Voice button again you can also say "Shuffle" (to have the system automatically pick the next song) or a variety of other commands (check you Sync manual for details.)
For some, it may be easier to transfer your music files to a USB flash drive. Then you can push the Voice button and say "USB." The Sync System will go to the USB to start playing music. You should be able to push the Voice button to call out "Play Artist The Beatles (or which ever artist you prefer)" and the system will find and play those songs. The command "Play All" resumes playing from the whole library on the USB stick. If you press the hard button on the console to access AM/FM or CD, you can return to the USB by pushing the AUX button. The iPhone streams better sounding music via Bluetooth. When you use a USB cable to connect your iPhone to the Sync System it defaults to the Mp3 format and has a lesser sound quality, but sometimes this connection will allow you to find music via voice commands (especially with the iPhone 4 or 4S).
