Leaving a network
There are a couple of mechanisms that will cause the router to leave its current PAN and attempt to discover and
join a new network based on its network joining parameter values.
These include the following:
 Change the ID command such that the current 64-bit PAN ID is invalid.
 Change the SC command such that the current channel (CH) is not included in the channel mask.
 Change the ZS or any of the security command values.
 Issue the NR0 command to cause the router to leave.
 Issue the NR1 command to send a broadcast transmission, causing all devices in the network to leave and
migrate to a different channel.
 Press the commissioning button four times or issue the CB command with a parameter of 4.
 Issue a network leave command.
Note that changes to ID, SC, ZS, and security command values only take effect when changes are applied (AC or
CN commands).
