Wireless Arduino programming using XBee’s

If you have an Arduino project where the dev board is stuck inside a machine, or attached to the rafters or is inaccessible in some other way, a wireless programming/debugging link will save you tons of time. This tutorial is an extension on Rob’s version. In this version, no extra firmware or hardware (other than a capacitor) is necessary. Just use the default bootloader. I demonstrate it with a ‘classic’ Arduino but of course this can be easily adapted to any version or clone.

You will need 2 XBee adapter kits, 2 matching-protocol XBee modules, an FTDI cable (or other FTDI breakout board, if you can wire it up correctly) and a 0.1uF capacitor (although sometimes a 1.0uF capacitor worked better)

The big trick is turning on “Digital I/O passing” where the reset pin is wirelessly mirrored from one XBee to the other. I spent a few hours reading the datasheet to figure it out!


Check out this diagram, can you tell I spent 5 minutes on it?

  1. Hi,

    Thank you very much for suggesting a smart way to reset remote XBee modems wirelessly!

    Best,
