Persistent Data
Once a router has joined a network, it retains the following information through power cycle or
reset events:
•PAN ID
•Operating channel
• Security policy and frame counter values
• Child table (end device children that are joined to the coordinator)
• A new 16 bit addr will be assigned upon rejoining the network.
The router will retain this information indefinitely until it leaves the network. When the router
leaves a network, the previous PAN ID, operating channel, and child table data are lost.
XBee Smart Energy Router Joining
When the router is powered on, if it is not already joined to a valid ZigBee network, it immediately
attempts to find and join a valid ZigBee network.
