I am very new to ZigBee networks and was just asked to help a customer build one that consists of two Xbee Pro modules that move around the facility, one coordinator on the upper floor and one router/repeater on the floor just below it.
I'm not so worried about signal/coverage but I am worried about the routers that are moving around being reliably able to quickly reconnect to the network.
Assuming that no new nodes will be added to the network in the future, what settings would impact stability when the existing radios are moving around or powering on/off often?
Also I have been having trouble understanding how to enable the minimum for encrypted payloads and was not sure if I must also configure "Trust Center" (KY) on top of "Network Encryption Key" (NK)? It just seems redundant to have two keys???
Is it as simple as adding the same "Network Encryption Key" (NK) to all routers and coordinators (and just ignore KY command)?
