Persistent data

The end device can retain its PAN ID, operating channel, and security policy information through a power cycle. However, since end devices rely heavily on a parent, the end device does an orphan scan to try and contact its parent. If the end device does not receive an orphan scan response (coordinator realignment command), it leaves the network and tries to discover and join a new network. When the end device leaves a network, it loses the previous PAN ID and operating channel settings.
