ESP32 Forum

Hello,
I'm having a problem with the serial monitor, when I send the program (https://pastebin.com/YtrS1DyG) on the esp32 everything works, but when I want to read the serial monitor, nothing is displayed and the LED stops flashing and restart when I stop the serial monitor (The monitor is set to 115200).
I tried with platformIO on Atom, VSC, Sublime Text 3 and on another PC, the same problems. On the Arduino IDE it works very well.

Maybe the trouble comes from my ESP? If anyone has a solution ?

Have you tried adding a delay after Serial.begin, or while (!Serial)?

Hello, I think it's not a code problem because it works very well with the Arduino IDE, Photo:

I have just found the trouble, just put Off DTR & RTS in the settings of the Serial Monitor (PlatformIO in Atom).
