A2DP panic problem
Posted: Mon Nov 02, 2020 9:06 am
Hey everyone!
I am working on creating my own voice assistant using IDF and ADF libraries. The application also uses such libraries as sh2lib (from protocols/http2 example), ESP-DSP and Tensorflow Lite. Moreover, the assistant can play music via A2DP stream (code taken from advanced_examples/wifi_bt_ble_coex example). And here a problem arises, because the application ran smoothly for about 48h and then the program broke down with the following Panic Handler:
At the time of the bug, on a device worked a thread from:
Does anyone know what the problem may be or experienced similar behavior, or can they advise me how to fix it?

CPU halted.
- The A2DP music stream
- Websocket requests handling
- HTTP2 requests handling (which waited for a new request using xTaskNotifyWait)
- Wake-word recognition thread which only performed vTaskDelay, due to muted microphones (which resulted in suspension of calculations)
- Recorder Engine Task to collect new audio data from I2S (Recorder Engine in only VAD mode)
Does anyone know what the problem may be or experienced similar behavior, or can they advise me how to fix it?
