void setup()
{
// Set up both ports at 9600 baud. This value is most important
// for the XBee. Make sure the baud rate matches the config
// setting of your XBee.
Serial1.begin(9600); //XBee/UART1/pins 0 and 1
Serial.begin(9600); //USB
}
void loop()
{
if (Serial.available()) //USB
{ // If data comes in from serial monitor, send it out to XBee
Serial1.write(Serial.read()); //XBee/UART1/pins 0 and 1
}
if (Serial1.available()) //XBee/UART1/pins 0 and 1
{ // If data comes in from XBee, send it out to serial monitor
Serial.write(Serial1.read()); //Serial port
}
}
Note: If you are using an Arduino Leonardo (or any ATmega32U4-based Arduino) and not a
Arduino Uno, make sure to change the switch to the hardware "UART" position. In this case, do
not need to add a jumper wire between the RST and GND pin.
