Hello,
I have done some work with Bluetooth modules in the past and have connected them to microcontrollers. However, I am still unclear as to what the best module for my applications is. My main point of confusion lies in whether or not a "profile stack" is needed for simple data connections.
For example, I can purchase a $70 module with built in SPP (Serial Port Profile) or a $60 module without it. With the $70 module, hook-up is fairly straigh forward. Just talk to the module over UART/Serial. If, however, I go with the cheaper module, how much more work do I have to do in the microcontroller to talk to the module? I'm sure this is somewhat module-specific, but in general, how necessary is the "profile stack"? Is it worth the extra $10?
Thank you very much for your comments.

Here are the two modules for comparison:
(look at the 2nd module and the 6th module )
Thanks again. :)
