NW (Network Watchdog Timeout)
This command applies to the XBee 3 Zigbee RF Module.
Set the network watchdog timeout used to ensure that a coordinator is active on the network (for example, a keep alive message).
If NW is set > 0, the router monitors communication from the coordinator (or data collector) and leaves the network if it cannot communicate with the coordinator for 3 NW periods. Alternatively, If DC bit 5 is set, the router will not leave the network but will instead attempt to rejoin the coordinator. The device resets the timer each time it receives or sends data to a coordinator, or if it receives a many-to-one broadcast.
