I've hooked up two XBee Adapter Kits, One with the USB -> FTDI cable and the other to my Arduino. Following Ladyada's excellent instructions I've programmed the computer one to transmit and the arduino-side XBee to receive. Both modules and my Arduino 328 are running at 57600bps. Both XBees have the same PAN ID.
However, I do not need to program the Arduino wirelessly, I only need to send messages to it. So I did not wire the receiver to the Arduino's reset button. But I did solder the jumper between RTS and D3 on the transmitter.
My wiring from XBee Adapter Kit -> Arduino is:
- +5 -> +5
- Ground -> Ground
- TX -> TX
- RX -> RX
I've written a simple patch in Processing to turn an LED on and off on the Arduino. It works great when the Arduino is connected directly to the computer via USB, however when I try to send over the FTDI serial port, it does not work. I know I'm selecting the correct serial port in Processing thanks to its Serial.list() command.
Any ideas for debugging? I'm at a loss for where to proceed from here...
Thanks!
