How Do I Transfer Data from one XBee Arduino to another XBee Arduino?
Series 1 or 2 xbee's? Already configured with X-CTU? Receiving random numbers -> baud-rates correct? If you receive random numbers, how do you know they are send properly?
IF the xbee's are properly configured what about just ignoring that they are xbee's and pretend it is a serial cable. Than it is a matter of Serial.available, Serial.read and Serial.print.
I recommend to focus on one single problem first before doing the complete project.
