== Set Xbee and Point to Point Network ==
* Connect your Xbee via arduino
* In the PC setting tab, set the baud rate at 9600, 8N1 for arduino serial port, click test/query
[[File:Arduino xbee manual settings.png|400px]]
* If the xbee can correctly read, you will see:
[[File:Arduino xbee manual test.png|400px]]
* turn to tabe "Modem Configuration" and click "read", in "Networking & Security" section, set channel to C and Pan ID to 1234
[[File:Arduino xbee manual configuration.png|400px]]
* repeat the process for another Xbee, then the point to point network is built
=== Test ===
* Turn to Terminal tab, any words typed will display on other xbee terminal

=== Arduino Demo Testing code===
Using two xbee on arduino together, change the B to A, and A to B in the following code, vice verse to another one. Then in one arduino you will receive AAA... and another you will receive BBB..

<syntaxhighlight lang="Arduino">
int ledPin = 13;
int val;

void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}

void loop() {
// send data to another XBee module
Serial.print('B');
delay(1000);

// receive data from another XBee module
val = Serial.read();
if (-1 != val) {
if ('A' == val) {
digitalWrite(ledPin, HIGH);
delay(500);
digitalWrite(ledPin, LOW);
delay(500);
}
}
}

== RSSI ==

XbeeRSSI.pde

This is a sketch for RSSI-Measurements. The sketch reads the incoming RSSI Value and turns on a LED if the Signal is strong enough.
Please note that the used Value (40) depends on your project environement.

ATTENTION!!!
---------------------------------------------
YOU HAVE TO USE AN ARDUINO WITH AT LEAST TWO SERIAL PORTS!
I am using an Arduino MEGA!
Connect your Xbee RX to Arduino RX!
Connect your Xbee TX to Arduino TX!
And don't forget the power supply!
RSSI Pin on Xbee -> 6
---------------------------------------------
