UNO+WiFi R3 ATmega328P+ESP8266 is not printing on Serial Monitor

Show a pic of your serial monitor, especially the lower right hand corner.

@felixbm

Serial.begin(9600);

That setting must be the same as the setting in your lower right hand corner.

Also, what is your debug setting, None? Try changing the setting to Debug.
