Xbee Tutorial

DFRobot Leonardo with Xbee R3 has a Xbee socket.It uses Serial1 to communicate with Leonardo.

Sample Code
// # Description // It is just used to test Leonardo module // Write by Grey // Input "p" once time the led will be turn on;twice to turn off. // It is controled by Serial1 Xbee side only. but you can check the status fr om serial port.
int ledPin=13;
int val;
int count=0;
void setup
pinMode ledPin,OUTPUT ;

Serial.begin 9600 ;

Serial1.begin 115200 // Xbee Serial1 port baud rate should be set the sa me to the xbee baud rate
void loop
val=Serial1.read // read xbee Serial1 data
if -1!=val
// "-1" means no data
if count==0 count=1 else if count==1 count=0;
digitalWrite ledPin,HIGH // Turn on Serial.println "LED ON" // you can check the status from serial port Serial1.println "LED ON" //you can check the status from serial1 port xbee . else if count==1 digitalWrite ledPin,LOW // Turn off Serial.println "LED OFF" //you can check the status from serial port Serial1.println "LED OFF" //you can check the status from serial1 por t xbee .
