You need to output to Serial1 or do mapping - please check this one.

- Sat Feb 20, 2016 8:59 am #41502 I now understand why. Using the Platformio/Arduino frameworks, you have tu use `Serial1` instead of Serial, both in setup and println.

Code: Select allvoid setup() {
  Serial1.begin(115200);
  Serial1.setDebugOutput(true);
}

void loop() {
 Serial1.println("Will go to UART1");
}


What you print to Serial1 won't show on Serial and vice versa. Hope this helps someone.
