There still existed an issue when switching pipelines between BT and WiFi. Due to periph_bt_pause() returning before the queue was emptied, and the audio pipeline pausing immediately which in-turn stops the queue from getting emptied. So inserting a small delay after periph_bt_pause() and before pau...

Fixed the issue without freeing and re-initialising the pipeline. Just had to set the event listener interface again, made it global so I could use it in the callback. Here is the code if anyone needs it in the future: ... } else if (cx_handle->work_mode == BT_MODE) { ESP_LOGI(TAG, "[ * ] Enter WIFI...

I solved the crash issue by using audio_pipeline_relink() instead of audio_pipelink_link(). Here is exact APIs call sequence I am using: ... else if (cx_handle->work_mode == BT_MODE) { ESP_LOGI(TAG, "[ * ] Enter WIFI mode"); cx_handle->work_mode = WIFI_MODE; ... periph_bt_pause(cx_handle->bt_periph)...

In the code have you included the required bt/ble header files?

I am developing a project based on the wifi_bt_ble_coex example using the LyraTD-MSC-v2.2 audio board. Our application requires the ESP32 device to switch between WiFi streaming and BT streaming. We removed the hfp stream part since we don't need it, and we replaced esp_audio APIs with audio_pipelin...

Try adding these function calls before your audio_pipeline_run()
