is it possible to lock somehow settings of coordinator module? For example by some HW pin, when it is in specific logic state, it won't be possible to change settings. Or is there any way how to disable possibility of changing the settings remotely, so it will be possible to change it only by wired UART?
My problem is that I am using ZigBee network to communicate with some devices and to collect data, but I found it is really easy with another Xbee module (as router) to hack this network (connect and change settings of some module).
Thanks for reply
