Hi DaZh_2976111 ,

Depending upon your application and codec requirements , you can put the 20706 in I2S master or slave mode in the application.

For example, refer to example in WICED SDK - /20706-A2_Bluetooth/apps/snip/bt/a2dp_sink

Refer event WICED_BT_A2DP_SINK_CODEC_CONFIG_EVT .

{

                route_config.route = AUDIO_ROUTE_I2S;

                route_config.is_master = WICED_TRUE; // will set as I2S master

            }
