Permit Joining - Digi XBee S2C Zigbee User Manual

Zigbee networks
Command Description
setting SC to 0x281 enables scanning on channels 0x0B, 0x12, and 0x14, in that order.
SD
Set the scan duration, or time that the router listens for beacons on each channel.
ZS
Set the stack profile on the device.
EE Enable or disable security in the network. This must be set to match the EE value
(security policy) of the coordinator.
KY
Set the trust center link key. If set to 0 (default), the link key is expected to be
obtained (unencrypted) during joining.
Configuration changes delay the start of joining for five seconds after the last change.
Once the router joins a network, the network configuration settings and child table data persist
through power cycles as mentioned in
attempt in the AI command register.
If any of the above command values change, when command register changes are applied (AC or CN
commands), the router leaves its current network and attempts to discover and join a new valid
network. When a Zigbee router has successfully joined a network, it:
Allows other devices to join the network for a time
n
Sets AI = 0
n
Starts blinking the Associate LED
n
Sends an API modem status frame (associated) out the serial port when using API mode
n
You can configure these behaviors using the following commands:
Command Description
NJ Sets the permit-join time on the router, or the time that it allows new devices to join
the network, measured in seconds. Set NJ = 0xFF to always enable permit joining.
D5
Enables the Associate LED functionality.
LT
Sets the Associate LED blink time when joined. The default is 2 blinks per second
(router).

Permit joining

You can use NJ (Node Join Time)
configure NJ to always allow joining, or to allow joining for a short time.
Joining temporarily enabled
Set NJ < 0xFF, to enable joining for only a number of seconds, based on the NJ parameter. Once the
XBee/XBee-PRO Zigbee RF Module joins a network, the timer starts. The coordinator does not re-
enable joining if the device is power cycled or reset. The following actions restart the permit-joining
timer:
