Hello,

I tested the A2DP sink function using "snip.bt.a2dp_sink" in WICED-Studio-6.4.  Program to CYBT-343026-02 , connect the I2S output according to the A2DP Sink Example on CYW20706 - Cypress Developer Community.

I use the phone  to connect CYBT-343026-02 by bluetooth ,and then play music.  It seemed that The CYBT-343026-02 can't receive audio stream. I also get the log, could you help to check it?

Hi,

I don't see any evident issue with the logs.  When, i tested the A2DP sink app from the latest Modustoolbox with CYW920706WCDEVAL board, I can see the streaming data when I connected a logic analyzer on the I2S DO pin. Have you tested it? 

The raw data is routed to I2S interface.

Thanks,

Thank you for your reply.  I have test the A2DP Sink Example by oscilloscope. It really has the streaming data on screen.  I check the  CYBT-343026-02 setting , it is the SW5 issue. It now works  well .

I also have another question , the hardware environment is the same as the upper A2DP Sink Example. But when I test snip.bt.hci_handsfree example ,  I  connect the  CYBT-343026-02 with the phone and make a call . There is no voice from the microphone, could you help to check the issue
