Arduino serial monitor not showing any output when ESP32-S3 connected to USB Port

[karunt]

Using Arduino IDE 2.3.2 on Windows 11 to upload the following sketch to an Adafruit Qualia ESP32-S3 board:

Code: Select all

#include <Arduino_GFX_Library.h>

void setup() {
  Serial.begin(9600);
}

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

USB CDC On Boot settings in Arduino set to

Enabled

.
After successful upload, the Arduino serial monitor doesn't show any output at all besides something like

15:04:15.106 -> ESP-ROM:esp32s3-20210327

I was told to manually press the Reset button on the board after uploading the sketch. But if I do that, the serial monitor shows the following error:

Port monitor error: command 'open' failed: Serial port not found. Could not connect to COM3 serial port.

Posted this question on Arduino forum also, but nobody has been able to help me find a solution to the problem. Without a functioning serial monitor, it's nearly impossible to see if my board and code perform the way they're supposed to. Is there anything else I need to do in Arduino to make ESP32-S3 based boards work? Thank you.

You can try to use a different USB Port.

My laptop has 2 USB ports. Used both. Same result.
