Bluetooth Profiles Explained
by Gregg Hall
The profile will also define the parameter ranges for each protocol. The concept of the profile is used to decrease the risk of interoperability problems between the different products. These profiles wont normally define any additions to the Bluetooth specification, which is why you can add new profiles where you need them. The Bluetooth underlying technology is the same, only the specific method that its used is defined.
Generally speaking, all profiles of bluetooth are based on the GAP (Generic Access Profile). There are 9 profiles that fall in the GAP category, and they are below:
1. AVRCP - Audio/Video Remote Control Profile 2. ESDP - Extended Service Discovery Profile 3. CIP - Common ISDN Access Profile 4. PAN - Public Area Network Profile 5. HCRP - Hardcopy Cable Replacement Profile 6. GAVDP - Generic Audio/Visual Distribution Profile 7. A2DP - Advanced Audio Distribution Profile 8. VDP - Video Distribution Profile 9. HID - Human Interface Device Profile
To put it another way, usage models will describe Bluetooth device applications and the associated profiles that are used. The usage model focuses mainly on three categories - voice/data access points, peripheral interconnects, and PAN (Personal Area Networking).
The voice and data access points involve connecting computing devices to communicating devices through a wireless link. This way, data can be transferred in a wireless manor, without the need of cables or other types of connectivity.
PAN is another very important usage model with strong appeal to business customers. Bluetooth networks are easy to set up in virtually any type of environment. An example would be meeting others at a trade show.
Instead of having contact information beamed via infrared, business cards can quickly and easily be transferred via Bluetooth wireless. The fact is that many documents can be exchanged this very same way - making the uses and possibilities virtually endless. The Bluetooth profile is very important to the specification, as it enables you to do so much more.
You can use peripherals and devices with the profiles, and virtually anything else that you decide. As Bluetooth expands and gets bigger and better, you can count on the profiles to expand and get even more functions. If you have experience with Bluetooth profiles, you should know exactly what they are and what you can do with them. If not, all you need is a Bluetooth device - and a vivid imagination.

Comments About Bluetooth Technology
To transfer mobile phone free ringtones using a Bluetooth, it is important to have both the mobile phones equipped with this wireless facility. The Bluetooth must be turned on on both the phones. This can be done by going through the MENU and then to the TOOLS folder. Within this folder there would be an option to select the CONNECTIONS. It is this folder that allows access to various wireless connections that could be established using the mobile phone. Bluetooth needs to be turned on here. Both the mobile phones between which the ring tone transfer is desired need to follow this procedure. Although there are a variety of phones available and each phone will have its own navigation process, the above mentioned procedure is largely true for most of the popular mobile phone models.

Pioneer introduced a hybrid navigation-cum iPod compatible entertainment system at CES. The AVIC-F500BT is designed to integrate with "virtually any factory audio system", the company said. Maybe. What the system does claim to do is add advanced voice technology for controlling iPods and Bluetooth-enabled mobile phones. The AVIC-F500BT can operate as both a navigation device and as a media centre, connected to an existing audio system via a line-in jack, the solution becomes a gateway for personal audio and communication devices. Built-in speakers and a rechargeable battery are also provided for use of the system while on the go.

Most personal area networking connectivity employed in electronic games is provided by Bluetooth, but experts predict "volatile" growth for the technology over the next four years. Bluetooth will grow strongly in the personal gaming market, and new data from ABI Research forecasts Bluetooth shipments for non-portable consoles to peak at over 115 million units in 2009 before declining to 2007 levels in 2012. "The gaming console market has a product lifecycle rhythm that ebbs and flows," said senior ABI analyst Douglas McEuen.
