NJ (Node Join Time)

This command applies to the XBee/XBee-PRO Zigbee RF Module.

Set or read the time that a Coordinator/Router allows nodes to join. You can changes this value at run time without requiring a Coordinator or Router to restart. The time starts once the Coordinator or Router starts, and the timer resets on power-cycle or when NJ changes.

For an end device to enable rejoining, set NJ less than 0xFF on the device that joins. If NJ < 0xFF, the device assumes the network is not allowing joining and first tries to join a network using rejoining. If multiple rejoining attempts fail, or if NJ = 0xFF, the device attempts to join using association.

Parameter range

0 - 0xFF (x1 sec)

Default

0xFF (always allows joining)
