Offroad: Programmable XBees
If you were wondering if there is a way to put some logic into the XBees have a look at the digi.com Website. Under "Learning Center -> Video and Recordings" you find a lot of XBee related video stuff. One of the recent additions to the XBee product line (see XBee/ RF Family Features Comparison) are the programmable XBees. They are called "XBee-Pro ZB (S2B)" (XBee-PRO Programmable Extended Range Embedded RF Modules) and have a 32 KB Flash/ 2KB RAM Freescale MC9S08QE application processor. You get full insight of the new Bees if you search for "Programmable XBee" in the video section.
