Hello Support,
I have problem with control of Cypress module. When I am trying to run A2DP profile by play YT music on paired phone it periodical change state player play-pause-play-pause-... on my phone.
I tried to debug where is the case and i found this #define function
#define GKI_send_msg(a,b,p_msg) wiced_bt_a2dp_sink_hdl_event((BT_HDR *)p_msg)
It is in library storage, and i dont think so that i should modify anything in here.
debug1 - screen from terminal to check where is the problem. When module going to play<>pause state UART debug stuck.
debug2 - code fragment with last used function.
When module start wiced_bt_a2dp_sink_send_start_response function everyting stuck.
Have you case like that with this module?
Best Regards
Piotr

Hello SheetalJ,
We found problem. CYBT-353027-EVAL schematic attached.
As you can see I2S_DO/PCM_OUT/GPIO6/P9 is the same pin. When A2DP is active, I2S_DO transmit data, in the same time button make a lot of impuls.
Solution is: comment button states, or change defined pin.

Hi @Piotr ,
I have tested A2DP with CYBT-353027_eval module before and it worked fine for me.
Would you please let me know demo application, MTB/WICED Studio version you are using? Also, mention any changes if you have made in code.
