Hi All,

I am using the Bluetopia stack, what command I need to call to send the PCM data stored in a buffer to a Bluetooth paired speaker?

Hi Henry,

Assuming you're using the A3DP Source sample application, please see the demo guide at: processors.wiki.ti.com/.../CC256x_TI_Bluetooth_Stack_AssistedA2DPSourceDemo_App

Hi Joseph,

I did read the link and I did check the A3DPDemo_SRC codes, but I still don't see where the audio is streaming. I did the following:

Start:

Inquiry

Display Inquiry list

Pair index (of sink device)

OpenSink index (of sink device)

Play

End:d

I could not find out how the audio data is sent to the Bluetooth speaker.

Regards,

Hi Henry,

With the Audio Source board, you can "Speak something through the Mic and the speakers should hear the output."
In you're using the A2DP Demo, then you can take a look at the "AudioEncoder.c" file.

Hi Joseph,

Thanks. By the way, the CCS A2DPDemo project is only configured for the Tiva Tm4c129x DK board, but I use the Tiva Tm4c123g DK board, how do I configure A2DPDemo project to run on the Tiva Tm4c123g DK board? I am just a newbie on TI Tiva Tm4c series, so is it hard? Otherwise, I will add the encoder.c to the CCS A3DPDemo_SRC project.

Thanks a lot,

Henry Nguyen
