Due to the flag `BT_HFP_HF_FLAG_CLCC_PENDING` is set when receiving the +CIEV or +CIND notification, the command `AT+CLCC` will be pending due to the flag is not cleared. Add a flag `BT_HFP_HF_FLAG_INITIATING` to indicate the HF initialization is ongoing. Add a flag `BT_HFP_HF_FLAG_QUERY_CALLS` to indicate the current calls list needs to be queried. Set the flag `BT_HFP_HF_FLAG_INITIATING` at the beginning of the HF initialization. Set the flag `BT_HFP_HF_FLAG_QUERY_CALLS` instead of setting the flag `BT_HFP_HF_FLAG_CLCC_PENDING` if the current calls list needs to be queried and the flag `BT_HFP_HF_FLAG_INITIATING` is set. After the HF initialization is done, query list of the current calls by calling the function `hf_query_current_calls()` if the flag `BT_HFP_HF_FLAG_QUERY_CALLS` is set. Set the flag `BT_HFP_HF_FLAG_CLCC_PENDING` if it is not set in the function `hf_query_current_calls()`. Signed-off-by: Lyle Zhu <[email protected]>
Add the function `bt_hfp_hf_query_list_of_current_calls()` to support users to query current call list. Add the callback `bt_hfp_hf_cb::query_call` to notify the received current calls. Signed-off-by: Lyle Zhu <[email protected]>
Add the command `query_calls` to query the current calls list. The received current calls list will be printed in callback `hf_query_call()`. Signed-off-by: Lyle Zhu <[email protected]>
The current calls list should not be queried if the SLC is not connected. Or the error `-ENOTCONN` will be returned by function `hf_query_current_calls()`. Check the connection status of HF before submitting a delay-able worker. Only the SLC is established, submit the delay-able worker. Signed-off-by: Lyle Zhu <[email protected]>
