Hi, I already tried a few libraries that I found on the internet about asyn functions. I know that the esp32 has 3 cores, but only 2 can be used. The setup() and the loop() functions uses the core #1 and in should be the core #0 free to use. The problem is that i'm not able start a function (that…

Check FreeRTOS if you would like to use multicore on the ESP32...

You can run multi-task code on a single core (usually Core 1) with FreeRTOS. You can also run tasks on Core 0, if you do it correctly.

The most useful reason to run the WiFi on core 0 is to avoid messing it up because of problems with user code. As others have said, its best to use core 1 for user code and FreeRTOS. Each core runs very fast, and FreeRTOS running on core 1 still allows the user to give different priorities to diffe…

The ESP32 has 2 processors with one processor having 2 cores. if using freeRTOS loop() should NOT have any code to run. #include "esp_system.h" //This inclusion configures the peripherals in the ESP system. #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include <driver/adc.h> #include …

Wait that means that the esp32 will not be able to connect to wifi? Because my esp32 is connected to wifi, and what I understand is that the wifi "runs" on core #0

I will check
