[SOLVED] ESP32 Serial monitor not working



I can build and upload the programs on my ESP32.
But when I run the Monitor Serial nothing happens and the LED stops blinking (the port and the baudrate are good)
I tried VS Code with PlatformIO and Sublime Text with Deviot same problems. While on the Arduino IDE everything is ok.

If anyone has a solution ? :slight_smile:


Could you reproduce this issue with a simple main.cpp?

#include <Arduino.h>

void setup() {

void loop () {


I just tried nothing, I try on another pc even worries, the problem could come from the ESP32



Does it work with Arduino IDE?


Yes, I have just found the trouble, just put Off DTR & RTS in the settings of the serial monitor.


Zh0nd, how can I do it?
