Hi,

I have connected a microphone via i2s on the CYW920719 board.

Is the only way to reroute the audio output from the microphone to A2DP through wiced_audio_start() and setting the route to  AUDIO_ROUTE_I2S?

Also, is there a way to sample the microphone digitially (it is a 24-bit microphone) as hex or bytes? 

Thanks so much in advance!

Hello,

Yes, I2S interface can be only used by A2DP . There is no other way. 

Please have a look at blog here: https://community.cypress.com/t5/Resource-Library/PCM-I2S-Clock-setting-in-CYW20706/ta-p/246335

Q: Is the only way to reroute the audio output from the microphone to A2DP through wiced_audio_start() and setting the route to  AUDIO_ROUTE_I2S?

A: Please have a look at watch demo example available in SDK

Note: Hope you also know that 20719 only supports A2DP source. Not A2DP sink.

Anjana
