Hi,

Have anyone used Continuous Integration of C/C++ with ESP32 either with GNU make or CMake?

Thanks,

Re: Starting wifi trips brownout

I need to detect brownout early. I manage to check my GPIO pin if goes down which is working for me.

I will stop any writing to SD card. but I also need to stop Wifi as well. how can I do Wifi stop. Is there any method.

Re: strange behavior with use of cpu=0 for application Tasks

ok, no worries. I will follow recommendations. use cpu=1 for all my applications tasks. set cpu=0 for wifi and LWIP in menuconfig. seem works for me so far.

It's under Component config -> ESP32-specific -> Panic handler behaviour.

Re: strange behavior with use of cpu=0 for application Tasks

I've seen similar behavior on a device I'm developing on a custom board that has a piezo for beeps and an RGB led. When wifi is connecting for, the piezo/led will stutter, even though they are being driven by FreeRTOS timer callbacks. I believe this may be caused by wifi blocking both cpu 0 and cpu...
