I'm currently doing a project involving creating a network protocol based on the 802.15.4 (not using ZigBee). My antenna is a Xbee 802.15.4 (part No.: XB24-AWI-001) and I'm working on a HCS12 (MC9S12DP256) and the IDE CodeWarrior.
I was wandering how we could change the configuration of the Xbee (like the destination address, the AES Encryption Enable and other settings that we can see with X-CTU) without a computer, so without the help of X-CTU (changing the settings of the XBee with the HCS12)?
Research on the Internet told me that we would have to send "+++" first to get in the AT mode and afterward, send the commands (ie: "ATDL 01" and "ATWR"), but it is not working for a reason that I ignore.
Thank you very much for answering.
