Greetings. Mr. Gustavo. Thanks for posting the update. Please note that the compilation gone again with error/warning: In file included from C:\Users\woodl\AppData\Local\Temp\.arduinoIDE-unsaved2024622-16084-1nys5hn.k2sy\sketch_jul22a\sketch_jul22a.ino:3: C:\Users\woodl\AppData\Local\Arduino15\packa...

Hi Araquel, The code created by the topic is for Arduino. Please inform which IDF code you are using. It's this one? Arduino Release v3.0.0 based on ESP-IDF v5.1.4 (latest)? Please report the error message. If you want to test compiling with the ESP32 IDF, try this: https://github.com/Gustavomurta/...

I tried to compile the sketch, but it is not compatible with latest IDF core 5.1 in Arduino IDE. Please, review the code.

The threat in my case has been solved accidentally. The board was Ai-Thinker ESP32-CAM, The GPIO3 has been grounded (flash mode set) and the power GND has been disconnected. The flashing gone successful. Magic!
