Use example code BLE_Audio_HAP_Central to audio function. The Central may start the stream fail, though the BLE connect and GAP link returns are OK. and Once the stream start failed, the stream cannot be start forever, with the result "CAP Unicast Start Procedure is Complete with status 0x91". Compared with the normal process the GAP link lack of CAP event 0x06, 0x12.
I have to use aci_gap_clear_security_db() then I can connect and start the stream successfully. And what's more, use aci_gap_remove_bonded_device() to remove the certain device and repairing cannot start the stream. It seems that there's some memory issues.

Hello Huang,
Could you explain your setup and the sequence used on the central from the first stream, including reset and/or disconnection ? Additionally could you share full logs from the beginning ?
Best regards,

compare the log, it seems that in CAP link process are abnormal, the CAP Event 0x06 is missing and CAP Event 0x12 is incompleted, the ASE ID 1 was missing. What's more, the CAP Event 0x06/0x12 are reported before Event 0x02.

Hello,
Thank you for your reply.
I see from the log you are based on STM32CubeWBA version 1.5.0 (and probably STM32WBA5).
Please, retry with the last release (currently 1.8.0 available on st.com) and tell us if you still see the issue.
Additionally, the scenario is important for us to understand the issue.
Best regards,

Hi,
Thank you for the logs. It seems ASEs states are not aligned between Central and Peripheral.
-Which peripheral are you testing against ?
-Does the peripheral supports GATT Caching ?
-Could you confirm you did not reset the central during the entire scenario ?
-Are you able to do an air trace ? we would like to check the behavior of the peripheral regarding the ASCS specification
"If the characteristic value for a bonded client changes when not in a connection and the value of the
Client Characteristic Configuration descriptor is configured for notifications, the server shall notify the new
characteristic value when reconnecting to the bonded client."
Here is few workaround proposal to be tested :
-force aci_gap_clear_security_db() (as you did with the joystick)
-use CAP_Linkup() with CompleteLinkMode set to 1

Hi,
The peripheral I'm testing is a TWS headset, vivo tws 3 pro, BLE5.3.
I'm not sure if it supports GATT Caching. what's the impact?
In the entire test scenario, I may reset the central with the reset button unconsciously and not clear the chip. I'm sure that after the first connection and start the stream successfully, I can reset the central or Peripheral then connection and start the stream successfully. After a disconnection for a while, 1~5 minutes perhaps, the stream may start fail. In this moment, the only way is to use ClearDB which will clear all bonded data. It's a rude operation and cannot be accepted.
Even I used to mention that I use aci_gap_get_bonded_devices()/ aci_gap_remove_bonded_device() to remove the Peripheral separately cannot solve this issue. why?
I will try to do the air trace and update the trace, but I'm not sure if the capture tools support this.
Also I will try to use CAP_Linkup() with CompleteLinkMode set to 1 and update the result.
