No serial output XIAO ESP32-S3

#1

I can’t get my XIAO ESP32-S3 to output to the Arduino Serial Monitor. This seems to be a common problem and I have tried almost all solutions for it, on this forum and elsewhere. Unfortunately without result. Can someone help me?

This is the sketch:

void setup() {
  Serial.begin(115200);
  while(!Serial);
}

void loop() {
  Serial.println("HELLO!");
  delay(1000);
}

In the Arduino settings, it makes no difference whether I set USB CDC On Boot as disabled or enabled.

Oops, solved… Directly after uploading there is no Serial Output, only when I disconnect the USB plug and reconnect it everything works properly.

Hi there,
or press the reset button. the C3 doesn’t always reset after programming upload.
