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.
Any help would be greatly appreciated.
Thanks in advance!

Hi,
CYW20819 is configured as i2s master in the watch app (in wiced_audio_start()). So the i2s mic giving the input should be a slave inroder to work the interface. And in master mode the clock rate for 20819 can be 16 kHz × 16 bits per frame = 256 kHz as per the spec (https://www.cypress.com/file/462851/download). Please ensure that these conditions are satisfied.
Also, May I know which I2S microphone are you using?
I will check whether there is any other restrictions to use i2s interface in 20819 chip or not.
Thanks,

Hi,
Could you please provide us more information on how you connected microphone to CYW920819 board?
Are you using any audio/codec board?
Thanks,

Hi,
I've connected it to J4.1 (Di), J12.6(WS) and J12.5 (CLK).
I'm not using another audio/codec board, just an I2S microphone.
