Re: Part IV: Fundamentals of Digital Debugging

Q:  Since the questions seemed to have slowed down i will use some of your xbee knowledge. When xbees are set up to run encrypted, is this done once at assmebly time or with each power up of the board? I was hoping to remove xbees from a device and turn off encryption then reinstall them so i can watch and emulate what each pic is saying to each other remotely.

 

A: In an XBee module you would set the EE (AES Encryption Enable) bit to a logic 1.  They you would load the KY register with the 16-BYTE value for the 128-bit AES key.  You can use the free X-CTU software to configure an XBee module (via adapter and a USB cable), or you can send it an AT-type command or an API packet via the X-CTU software, or from a serial port on an MCU connected to the XBee module.  You cannot read the KY register.  Parallax and Sparkfun have USB-to-XBee adapters.  Look for my book, "The Hands-On XBee Lan Manual," which should come out in the sprint 2012.  It doesn't cover AES encryption, but now you know how to do it.
