I have a customer requirement where a i2s voice stream is generated, this needs to feed in to one of our BT modules based on the 20719, which takes this stream and transmits it over BT to a headset/speaker.

Do we have examples of I2S input instead of output? could this be supported on one of modules?

thanks

CYW20719 support A2DP source as well as HFP.

You can refer to the watch example which implements A2DP source. The data path will be as follow:

Audio Source(Mic, stored file) -> Codec -> (over I2S) -> CYW20719 -> BT

Similarly, this is possible when using HFP as well.
