BLE_ERROR_INVALID_CONN_HANDLE of ATVV service when master not support ATVV.

SDKv14.2  SR3v.12

Hi , My smartphone not support this service ,  error occurs when RCU trying to activate ATVV audio function,and causes system reboot because there is an error check. 

It occurs in static void m_coms_process_data(void) -> err_code = stream_processors[rr](&status)  which is static ret_code_t m_coms_process_audio_atvv_ctl(m_coms_data_process_status_t * p_status) -> m_coms_ble_atvv_ctl_pkt_queue_process() -> ret_code_t ble_atvv_ctl_send(ble_atvv_t const * p_atvv, uint16_t conn_handle, ble_atvv_ctl_type_t type,  void * p_param)   

Last function returns BLE_ERROR_INVALID_CONN_HANDLE, can I just ignore this error?   If this error comes from ATVV , then ignore the error,something like this?  

Because I dont want the RCU keeps rebooting just because the master doesn't support ATVV service.

Thanks.

Hi, 

ble_atvv_ctl_send is the function for sending control and error messages to the peer. BLE_ERROR_INVALID_CONN_HANDLE means Invalid connection handle in the SDK General error codes. It should be find to handle this error as you want if there is no ATVV service.

Best regards,

Amanda

Hi,

Don't see any way to handle theses errors from General error codes.

Most important is that error doesn't get handled in that moment , so this error is a unknown error in the log. 

If other locations have the the way to handle it , maybe I can just copy the way?

No.

For your requirement, please set CONFIG_AUDIO_ATVV_ENABLED to 0 in the sr3_config_nrf52832_pcaXXXXX.h file to disable ATVV Service. Then it will not check the connection.
