So how would we go about setting up our series one Xbee's.
Set PAN ID, MY, and DL. Leave EVERYTHING else alone. MY on one matches DL on the other, and neither is 0x000 or 0xFFFF.
For instance, set one up with PAN ID = 3333, MY = 8001, and DL = 8000. Set the other with PAN ID = 3333, MY = 8001, and DL = 8001.
Then how would we go about editing our current code to get the wireless to work?
Create an instance of SoftwareSerial, using pins 2 and 3, called xbee. Then, use xbee.begin(), xbee.print(), xbee.write(), xbee.println(), xbee.available(), and xbee.read(), just like Serial.XXX.
