Lora 32 V4 Serial outputs nothing

#1

I am totally new to ESP32 and Arduino in general, so sorry for my simple question. I expected to see text in the Serial Monitor, but there is nothing. What am I doing wrong?

void setup() {
  Serial.begin(115200);

  delay(1000);

  Serial.println("Your message");
}

void loop() { 
  Serial.println("I am here");
  delay(1000);
}

Other examples displaying text on the OLED screen work perfectly. But, this super simple one doesn’t work as expected.

Maybe…

It was related to a lost licence after installing Meshtastic, see License problem on WiFi LoRa 32(V3) for the solution.
