XBee with sparkfun shield

Hi,

I am using following setup and trying to communicate two Xbee modules:

I am having some problems with serial.read and serial.available

I made the setup through the guide given on http://blog.kevinhoyt.org/wp-content/xbee-setup.pdf

and uploaded the code

#define ledPin 13
byte pinState = 0;
void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}
void loop() {
Serial.println("testing...");
// toggle an LED just so you see the thing's alive.
toggle(13);
delay(1000);
}
void toggle(int pinNum) {
// set the LED pin using the pinState variable:
digitalWrite(pinNum, pinState);
// if pinState = 0, set it to 1, and vice versa:
pinState = !pinState;
}

I managed to see “testing…” on X-CTU terminal.

However I tried to use this following code given on the tutorial of serial.read.

int incomingByte = 0;	// for incoming serial data

void setup() {
	Serial.begin(9600);	// opens serial port, sets data rate to 9600 bps
}

void loop() {

	// send data only when you receive data:
	if (Serial.available() > 0) {
		// read the incoming byte:
		incomingByte = Serial.read();

		// say what you got:
		Serial.print("I received: ");
		Serial.println(incomingByte, DEC);
	}
}

But I dont get any response from X-CTU terminal. I did write number even words but no response. I am an Arduino newbie so I will be glad if you help me on what to do.

In general I was able to get data from my Arduino board through Xbee but I couldnt make Arduino work according to my commands put in X-CTU terminal.

I setupped it again and solved it. As I heard it might take a few restores to make it work properly
