    Hi I have never used bluetooth before, however I have programmed AVR's in C.
    I want to make a bluetooth dongle that transmits pcm audio that is being generated from one of the pwm pins of my AVR. That currently works - i.e I can hear it through head phones.
    I have one of these:

    I cant quite figure out how to use it for what I want to do though. I think I should be able to just connect the digital pin to one of the pins of this module and transmit audio.

    I assume I initialize it with the SPI interface, and it says it has an A2DP profile, but Im not sure of the wiring or where to start with the code, and I cant find anyone doing anything similar online.

    Any help would be greatly appreciated.
