I connect Arduino Yun to my Computer with WiFi. I was able to get the IP address of my Arduino Yun. However, when I try to print something. It seems to not work at all. The following code is the one that I try:

void setup() {

void loop() {  
 // print labels 
 Serial.print("NO FORMAT");  

I did not get any kind of error. However, when I open the Serial Monitor, it shows nothing at all. I try to use the same code with Arduino Uno. It works fine.

  • double check the port, also check in Device Manager if there is the Yun in Ports. It might be the missing driver

When using the Yun over wifi, you cannot user Serial, you need to use Bridge Console object. Serial is bound to the usb cable.

Give a spin to ConsoleRead example.
