Serial Monitoring does not work

[peteh]

I'm using the sample project but I cannot get serial monitoring in vscode to work. Any ideas?

I set monitor_speed in the platform.ini to match serial.begin(speed).

not sure if you ever found the solution:

if you are on framework = arduino you can add this to your platformio.ini

monitor_speed = 115200
build_flags =
    -DARDUINO_USB_MODE=1
    -DARDUINO_USB_CDC_ON_BOOT=1

Hi thanks for the reply, I'm still struggling and monitoring in platform io does not return anything: platform ini

Code:

  Serial.begin(115200);
  Serial.setDebugOutput(true);
  delay(500);

  Serial.println("\n=========\nTesting...\n=========\n");
  log_e("TESTING...");
}

void loop() {
  log_e("TESTING LOOP...");
  Serial.println("Loop...");
  delay(1000);
}

Can anyone tell me how to get the Serial Monitor to work with Arduino?
