Hi,

I have a microphone connected to my CYW920819 board via i2s.

Unfortunately I am unable to get it to stream to my bt headphones via a2dp (is it even possible?)

I am using the watch example for this board and followed the blog below to route i2s.

https://community.cypress.com/t5/Resource-Library/PCM-I2S-Clock-setting-in-CYW20706/ta-p/246335?emcs...

Could it be a codec issue/sampling rate issue?

Any help would be greatly appreciated.

Thanks in advance!

Hi @MaCh_4826131 ,

Apparently I2S input feature on watch CE is supported only on CYW20721 platform. It is not possible to receive input using a microphone via a codec on CYW20819 over I2S.
