But in stack profile 0x02, also called ZigBee Pro, it is possible to set the network short address explicitly. In this case, the commissioning tools would know the short address to assign to each node, perhaps based on some formula involving hotel room number. Then, when the node is reset, it can either use the rejoin as above, or even silent join (with StartupControl set to mode 0x00) so that it can be done a little faster (no waiting for negotiation with the trust center). It’s assumed in this case that the tool has all the necessary keys and has communicated them to the nodes. |
