Watchdog issue

[tutoduino]

Hi,

I face a watchdog issue in the example bt_music_sender with an ESP32-WROOM streaming to JBL GO 2 Bluetooth speaker. I can solve it adding a 10ms delay in the callback before returning, but I am not sure it is a good idea... I see another error, which I do not think is related to: Invalid AVRC event: 6 Here are the debug traces :

My project is to build a web radio, with stream collected by ESP32 via Wifi and sent to JBL GO 2 speaker via Bluetooth. Thanks for your help.

Adding a delay is the only reliable way to resolve watchdog errors.

The actual updated version is issuing warnings instead of errors for unhandled events, so don't be worried about this. I also extended the BluetoothA2DPSource logic quite a bit.

Thanks. I discover that new ESP32C3 does not support anymore A2DP, that's a pity! It is not possible anymore to stream music to Bluetooth speakers on such microcontroller?

Hi, sorry to reopen this issue but I'm using the same sketch, bt_music_sender with an ESP32-WROOM, and I keep having some stuttering because of the mandatory delay( 1 ) call. If I remove it, the sound is crystal clear but then the watchdog event occurs after 5 seconds and my device reboots...

Is there any solution to that problem? Maybe requesting less samples would avoid starving the other threads, is this configurable?

Thank you for your time and for your amazing work!

Did you try to increase the delay to give the a2dp task more time ?

Hi, I was talking of the delay( 1 ) call inside the sampling loop callback, where we feed samples to the A2DP. if I increase the delay there then the stuttering gets worse. If I increase/decrease the delay() in the main loop() function, nothing changes... :/
