state 2x per second after the end device has joined. At this point, the operating channel and PAN
ID can be read using the CH (Operating Channel) and ID (PAN ID) commands. The 16-bit network
address of the end device can be read using the MY (16-bit Source Address) command. If API is
enabled (AP parameter > 0), the API modem status "Joined" is sent out the UART. If the JN
command is enabled, the router will send a node identification packet to the coordinator. The AI
(Association Indication) command can be used at any point during the router join routine to know
the status of the startup operation.
Once a coordinator has started, or a router or end device has joined the network, the device will
continue operating on that channel and PAN ID unless one of the following occurs:
1. The ID parameter changes.
2. The SC parameter changes, such that the current operating channel is not included in the
new SC parameter
3. The NR command is issued with either 0 or 1 as a parameter
If any of the above occurs on a coordinator, the coordinator will attempt to restart on a channel
and PAN ID based on the new saved ID and SC commands. On a router or end device, the above
conditions will cause the device to leave the network (if previously joined) and attempt to join a
new PAN using the saved ID and SC parameters.
