desired network.
In the XBee firmware:
1. Set NJ (Node Join Time) to a value less than 0xFF on all routers and coordinator devices to
disable joining.
2. Use the Commissioning pushbutton or CB (Commissioning Pushbutton) to enable joining for a
short time; for more information, see Network commissioning and diagnostics .
Application messaging framework
If none of the previous mechanisms are feasible, you can build a messaging framework between the
coordinator and devices that join its network into the application. For example, the application code in
joining devices could send a transmission to the coordinator after joining a network, and wait to
receive a defined reply message. If the application does not receive the expected response message
after joining, it could force the device to leave and continue scanning; see NR (Network Reset).
