Hello all,
I've used XCTU to configure the two XBee's (The mega one as a router, and the uno one as the coordinator). They can communicate successfully in XCTU, however, when I try to use an arduino sketch, I don't see anything on serial communication.
On the uno: I'm using the pins RX and TX on the uno like this: DOUT -> TX & DIN -> RX.
On the mega: Same thing, using the TX and RX, DOUT -> TX & DIN -> RX
On the router side (mega), I am trying to send H & L, using this code:
#include <SoftwareSerial.h>
#define rxPin 6
#define txPin 7
//Xbee serial connection.
SoftwareSerial XBSerial(rxPin, txPin);
void setup()
{
Serial.begin(9600);
//Start xBee Serial Bus
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
XBSerial.begin(9600);
}
void loop()
{
XBSerial.write('H');
delay(1000);
XBSerial.write('L');
delay(1000);
}
And on the receiver side (uno):
#include <SoftwareSerial.h>
#define rxPin 6
#define txPin 7
//Xbee serial connection.
SoftwareSerial XBSerial(rxPin, txPin);
int incomingByte; // a variable to read incoming serial data into
void setup() {
// initialize serial communication:
Serial.begin(9600)
//Start xBee Serial Bus
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
XBSerial.begin(9600);
void loop() {
// see if there's incoming serial data:
while (!XBSerial.available())
// read the oldest byte in the serial buffer:
incomingByte = Serial.read();
Serial.println(incomingByte);
// if it's a capital H (ASCII 72), turn on the LED:
if (incomingByte == 'H') {
digitalWrite(ledPin, HIGH);
}
// if it's an L (ASCII 76) turn off the LED:
if (incomingByte == 'L') {
digitalWrite(ledPin, LOW);
}
}
Any help would be great!
