CC256XQFNEM: A2DP play music sounds intermittently....

beyondeva

Part Number: CC256XQFNEM

Hi all

We found that there is only one DUT that is connected to a Bluetooth headset to play music, and the sound of Bluetooth music will be intermittent....

The connection status is Ok, and the distance is close, and the antennas are also good.

Other samples(DUT) using the same software version will not have this phenomenon,

so how to confirm the hardware problem. could you tell me...

thanks

Hejun,

What is the host MCU on your system? Are you using the A2DP demo from our SDKs?

Thank you for your reply.

The host Soc is H3(Renesas).

I think we should not have used your SDKs...

I found that this phenomenon seems to be related to the software.

Once the new Bluetooth device is searched (pair the new BT device)in user UI button,

the sound will be intermittent.

Once it stops searching, it will play fluently....

so I don't know how to check the possibility of hardware problem...

Hejun,

If you'd like to debug this further we would need to see if it Audio Buffers are under flowing or overflowing, and identify where the source of the intermittent data is.

If not i will close this thread.
