Part Number: CC2564C

Tool/software: Linux

Hello,

1. Connected with a headset device via HF profile.

2. BLE function is enabled.

3. Receive a incoming call and accept it. At the same time SCO(WBS) channel will be initiated.

4. Before establish SCO the BLE function will be firstly disabled.

5. Then the process of establishing SCO is blocked with a about 30% reproduce rate also based on this special Sennheiser headset device more easily.

I attach air sniff & FW log, help check the cause please.

Thanks.

Hi Peijie,

Do you see this issue only with these special headset or multiple headsets? Does the same issue happen when BLE is always disabled (in other words, only AVPR add-on downloaded to the CC2564C)?

These details may help us better understand the issue.

Best regards,
Vihang

Issue just happened on these special headset currently.
Issue will not happen when BLE is always disabled.

Also issue will not happen when accept the incoming call manually, the above operation are set that call is accepted automatically.
