Hi all,
I need your help about my FW code in esp-idf (Compiler version: 5.2.0).
My Board is LuaNode: https://github.com/Nicholas3388/LuaNode

I have one task with priority 12 (worker task) which I created in my main entry point (with xTaskCreate API) which every 20 sec gets from cloud (using http calls), some setting parameters and then enable/disable the web_radio streaming using an i2s device (both HW and FW I used for the radio streaming are from Mr. BuddyCasino project on :https://github.com/MrBuddyCasino/ESP32_MP3_Decode).

As shown in the web_radio.c the streaming task is created with the xTaskCreatePinnedToCore API and has a priority of 20 running on core 0.
I'm getting some error related (I think) to task synchronization like in the following lines :

I (39271) audio_player: Buffer fill 95%, 30708 bytes

How can I solve this problem?
Could it be some problem related to the shared resource (for example the WIFI) between the two task which causes a sort of dead lock or something like that?

Hope you can drive me on the right direction.
Thanks in advance

Your mp3 task is not yielding and causing the WD timeout. That's OK if you want it designed that way. Sounds like you are checking for something and looping versus waiting for a semaphore or sleeping, which would allow the idle task to process.

Dear John ,
you are right .
I had some semaphore blocking my code.
I solved by removing it: now the streaming is good
Thanks a lot.
