I'm having trouble with getting the Simple Example (arduino.cc/en/Guide/ArduinoXbeeShield) for communication between two Arduino's with XBee shields.
The trouble I'm having is that the sender seems to be sending out the 'H' and 'L' in the code properly (they show up in the Serial Monitor and they seem to show up on the voltage meter when hooked to pin 3 (DIN) of the XBee module). However, while the receiver is receiving the same (it shows up on the voltage meter when hooked to pin 2 (DOUT) of the XBee module), the Physical LED code sample fails to turn the LED on and off. I assume this is because it doesn't recognize the received bytes as 'H' and 'L'.
I tried sending the byte taken from the Serial buffer again, so they show up on the serial monitor and I get the following sequence:
152, 224152, 128152, 224152, 128152, ad infinitum
Clearly, the bytes in the buffer don't match up with what I think I was sending. Any ideas on where this is going wrong?
