Hello guys. I am stuck at getting my 2 Xbees to communicate to each other. I am doing exactly same excersise as this guy on youtube:
. I have connected my Xbees accordingly and I have run the program but my serial monitor is empty and im not getting any data. I have written some additional code to turn on Arduino LED 13 to confirm that the loop is working and the LED turned ON. Somehow my router does not send the data to coordinator. I have added some pictures . Can someone give me any advice how to troubleshoot and test it properly? Thank you very much!

Okay i realised another thing.

if (Serial.available() >21){
digitalWrite(led,HIGH); //turn on Uno LED

for (int i=0; i<22; i++) {
Serial.print(Serial.read(),HEX);
Serial.print(", ");
}
Serial.println();
}

If i write a code digitalwrite after the first if stetement, the LED will not turn OFF meaning that it never satisfies the condition.
