CCS/CC2564CMSP432BTBLESW: The audio can't work from speaker product to Ti Device

Did, you make the HW modifications to the CC256XCQFN-EM board, as mentioned in the User's guide (http://www.ti.com/lit/ug/swru493a/swru493a.pdf)

Thanks

Do you mean modify the CC256XCQFN-EM at R19,R18,R11?

if it is this thing, I was already do this. The  page 5 of the User's guide has  mentioned. (http://www.ti.com/lit/ug/swru497a/swru497a.pdf )

After do this the HFP_AG also can't send the audio to Ti Device from Speaker product.

The result is my question , It's not solved. So I came here to ask for help.

Thanks

I tried something that I changed the AudioUseCase of HAL.c

     case aucHFP_HSP:

         InputLine = CODEC_LINE_IN;

         OutputLine = CODEC_LINE_OUT;

InputLine is the audio from Ti Device to Speaker

HFP_AG Demo of SDK is

         InputLine = CODEC_ONBOARD_MIC;

It is open so the channel is busy, the speaker can't sent the audio to Ti Device.

I change it

InputLine = NO_INPUT;

But it had echo on my speaker. The audio will play on speaker and CC3200AUDBOOST at the same time.

Finally,

        InputLine = CODEC_LINE_IN;

and I don’t use cable input the CC3200AUDBOOST.

So the channel is not busy, I can let the speaker send the audio to Ti Device.

I don’t know is this the best solution but I can use it. If anyone have other idea can tell me.

Thanks

The configuration of the Audio codec's input and output ports/accessories are only suggestive.. The intent of the demos are to show case the BT Audio/profile stack functionality. So, you may change Audio codec (TLV320AIC3254) configuration, as needed to your usecases..

Thanks
