I am trying to set up two Xbee Pro 900HPs.
Device A is the transmitter and takes a digital input.
Device B is the receiver and outputs the same signal.
I am using the Grove Development board kit and trying to use the User Button for input on Device A and the User LED for output on Device B.
DH SH from B
DL SL from B
D4 Digital Input 
D4 Digital Out, High 
I am expecting the user light on the Grove Development board to turn on when D4 is forced low. Nothing happens to the LED on the Grove board for Device B when I hit the user button on the board for Device A. It looks like B is getting data from A because the Mac Statistics and Timeout show changes after I hit the button for A.
Am I going the right direction with this or way off?
