BT(A2DP) restart crash (AUD-1959)

[iloop2020]

If the BT service is start->destroy->start, it crash.

1. bluetooth_service_start()
2. bluetooth_service_destroy()
3. bluetooth_service_start()

Snap of code at esp-adf/components/bluetooth_service/bluetooth_service.c:437 ESP_ERROR_CHECK(esp_bt_controller_mem_release(ESP_BT_MODE_BLE));

Why it is ESP_BT_MODE_BLE ?

Thank you

Hi Any update ?

Hi

If ESP32 is connected with SmartPhone by A2DP sink, can esp32 terminate the connection ?

Thank you.

Hi, I have the same problem on esp-idf v4.1 and esp-adf v2.3, is there a solution? The following is the error log information.

Hi @jyh-cmd @iloop2020

I suggest you to use pipeline stream way to control bluetooth. Use pipeline run/stop, pause/resume.

The reference routine is this, https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_a2dp_sink_stream
