What model / series Xbee's do you have?
As to returning data to the PC. Check the DL & DH parameters on the remote unit. They need to match the SL & SH parameters of the unit on the PC.
I don't think any one has had success with XBee Explorer Regulated (starter kit) and Axon2-
I use a Sparkfun Xbee Explorer Regulated and Axon1 with no problems at all. Is the starter kit one different?
It was only a couple of days ago and I remember that you could update the sparkfun one to work if you could solder SMD devices... Kurt
No, its the same (correct me guys if i am wrong). The only thing different her is that i use Axon II. Can you please tell me how did you set up your Xbee's (PC and microcontroller side). Did you use the XCTU software ?
As I mentioned in a few other threads I had problems with the sparkfun regulated explorer with my Axon2, which is why I went to the Selmaware one and have had no problems.It was only a couple of days ago and I remember that you could update the sparkfun one to work if you could solder SMD devices...

Try swaping radios and have your AXON print something out continuously, I bet you will see it on your computer, but not be able to control the robot.
Well, swamping them and same result rules out configuration issues, so it must be electrical. check your wires, try new wires, etc. Any chance you have an oscilloscope?
Try this, (and it's random, i know). Add a 1k resistor in series of the Axon's TX line on that Uart, in-between the Axon and the Xbee board.
