Hello All,

     I was trying to implement a new use case in which audio data has to be processed by codec DSP. so with SPI  I am trying to read audio data from codec memory region. But here I am facing one issue that is I am unable to find API's to give audio data packets. I am using latest-v3.x wiced_btsdk. In available sdk I2S is configured to route audio data but how audio data is handling in I2S interrupt handler and transferring to BT controller code is hidden it seems. so can anyone help me How Audio data is routing to BT stack. Even in playback case also I am unable to understand How Audio data is SBC (or) any codec  standard decoded and sent to codec.

Thanks in Advance.

Hello @Nagarjuna_k 

As per my knowledge, for our BT audio chips, you can't access audio data in application layer. 

However I will double check with our software team if there is any other ways you can accomplish this requirement .

Hi @Nagarjuna_k 

Sorry I missed to respond to you.

I checked internally. There is no option to access the audio data in application layer as similar to your requirement .
