One of these days I will go back and make the XBees my be-atch. They're going to work whether they want to or not.
What kind of XBees are they? Series 1 models are trivial simple to make talk to each other. Fire up X-CTU, change 3 parameters and write the changes, and they work. Series 2 are not that much more difficult.
Specifically, they are XBee-PRO ZB S2B.
I can get them to work in X-CTU, I can talk to them and all. Even burned a new firmware. However, getting them to talk to one another still eludes me. They've been sitting on a shelf for the better part of the last 12 months now ... The project for which they were originally intended went on with Nordic modules instead, so these guys took a backseat. But, I would love to revive them and get them to work.
