Suddenly debug info from Serial

Hi!

I've got a project where I use Serial.read() to send simple commands to the Arduino (e.g.: pressing 's' skips an mp3). However, suddenly I'm reading something like debug info from the Serial. For example:

time="2018-12-11T11:04:32-04:00" level=info msg="[]"

Because of this my Serial.read() is triggered and he's executing the function that only needs to be executed when I manually send a character to the Serial port.

I have no idea how this information is suddenly printed to the Serial port. Is this a debug setting in my code? Is it an option in the Arduino Create editor? Is my Arduino board doing some weird things? :wink:

Thanks if someone can help me with this!

It is rather difficult to help when you have not posted your program or even told us what Arduino board you are using.
