HFP AG connection.

Postby allex1978 » Mon Apr 15, 2019 9:58 pm

Hi, i`m trying to rebuild a2dp_sink example to HFP and can`t open AG. I enabled Voice Over HCI via menuconfig. Then added

Code: Select all

        
esp_hf_client_init();
esp_hf_client_register_callback(esp_hf_client_cb);
esp_hf_client_register_data_callback(esp_hf_client_incoming_data_cb,esp_hf_client_outgoing_data_cb);
esp_bd_addr_t remote_bda = {0x24,0xda,0x9b,0x76,0xf4,0x5a};
esp_hf_client_connect(remote_bda);
to main.c
added callbacks to bt_app_av.c

i`m trying to use esp_hf_client_connect_audio after Service Layer is connected. esp_hf_client_connect_audio function sends AT+BCC then AT+BCS=1 then got OK responce and stops. HPF Audio connection state changed to "Connecting" but never get the "Connected" state. ESP32 disconnects from phone when i`m trying to make a call. hf_client_data callbacks are never fire.

i added some ESP_LOGI("hf_mydebug",....) to bt functions to trace the events and got this:
