I have an idea I want to implement using Bluetooth technology. I want to have two bluetooth devices exchange RF data within a short range. How can I buy individual bluetooth chips and their accessories to build the circuits? Also, does it come with documentation? I appreciate your help.

Hello,
Many providers of Bluetooth devices provide you with a design kit. This documentation will allow you to copy an existing design and use it. Some provide you even with an evaluation card that will help you to develop your application. Not clear what you mean by "accessories", but if you mean devices supporting the Bluetooth chip (or chip set) then they are specifie dclearly in the documentation. Do you think you could take advantage of distance measurement between the devices in your application? There is an evaluation card made available with Bluetooth solution that allows you to measure accurately the distance between the two communicating. Those kits sometimes are expensive ($5K), so you need to do a search to find the one fits your needs.       Good Luck.

There are many companies that provide Bluetooth devices. With regard to distance maesurement capability, to teh best of my knowledge, Bluesoft is the only one that has an evaluation card.

OK here are my 2 cents.
So far not many companies sell their modules in low volumes. A very hard part is the soldering of the modules since the smd packages have very very small footprints. I have bought some Mitsumi Modules with intergrated antenna, from the local dealer in germany, and i am sure you can find a local dealer near you. You can of course buy some allready made Bluetooth product which offer Serial port functionality. Keep in mind though that you will not be able to alter their code( the upper layers of the stack) so you will just be using them like a simple serial cable. The module Solution is the most appropriate for developers, since the only firmware you get with the modules is the lower HCI part, and you can implement the upper layers with your application code, on a seperate microcontroller. You can also try www.btdesigner.com/qualmod.htm but i have had no luck there..
Good luck
