Group Table
The coordinator retains this information indefinitely until it leaves the network. When the coordinator
leaves a network and starts a new network, the previous PAN ID, operating channel, and child table
data are lost.
Coordinator startup
The following table provides the network formation commands that the coordinator uses to form a
network.
Command Description
ID
Used to determine the 64-bit PAN ID. If set to 0 (default), a random 64-bit PAN ID will
be selected.
SC
Determines the scan channels bitmask (up to 16 channels) used by the coordinator
when forming a network. The coordinator will perform an energy scan on all enabled SC
channels. It will then perform a PAN ID scan.
SD
Set the scan duration, or time that the router will listen for beacons on each channel.
ZS
Set the ZigBee stack profile for the network.
EE
Enable or disable security in the network.
NK
Set the network security key for the network. If set to 0 (default), the coordinator uses
a random network security key.
KY
Set the trust center link key for the network. If set to 0 (default), the coordinator uses
a random link key.
EO
Set the security policy for the network.
Configuration changes delay the start of network formation for five seconds after the last change.
Once the coordinator starts a network, the network configuration settings and child table data
persist through power cycles as mentioned in
.
When the coordinator has successfully started a network, it:
