Hello there!
I'm working on an ESP32 in the Arduino framework with a FreeRTOS architecture.
I use a task to control an MCP GPIO expander with 4 encoders working on it. The code also uses wifi, mqtt, displays, and a stepper motor.
Occasionally, my encoder task is not responding, but the motor task keeps running the motor.
This is killing me because the encoder uses a stop button to stop the motor for safety, and not being able to stop the motor is pretty concerning.
I would like to ask if someone has seen a similar issue with wifi / mqtt tasks. I think that the wifi task is hanging when the wifi or mqtt drops.
The wifi / mqtt task is running in a different core than the encoder task. The encoder task has a priority of 23.
I would appreciate any help on how to start tracking this issue because I haven't been able to replicate it.
Thanks a lot in advance
