    A2DP source with I2S microphone

      Hi,

       

      I'm developing an audio application with the CYW920719Q40EVB_01 and Wiced Studio 6.2.

       

      I tried to use the demo/watch example and I modified it as an A2DP source routing with I2S instead UART ( "wiced_audio_start( WICED_TRUE, AUDIO_ROUTE_I2S, lcid, &av_app_cb.sbc_caps_configured );" ). And I use the default configuration of pins , ( platforms/CYW920719Q40EVB_01/wiced_platforme_pin_config.c ) where clock = P16, WS = P17, DO= P02 ans DI=P04. But Clock (pin 16) stay at high level.

       

      I tried to use others pins or configure I2S in slave mode. But they both did not work. The example works well when I'm using uart or sin routing. According to this post, my solution should work https://community.cypress.com/thread/36044?q=I2S

       

      Do you have any clue about that it's working wrong?

       

      Thank you,

       

      Thibaut.
