» ZB 01b: Coordinator reset

This program shows how to set reset a network from the coordinator. After reseting the network a new PAN ID is set.

Required Materials

1 x Waspmote
1 x Battery
1 x MiniUSB wire
1 x XBee-ZigBee module

Notes

- To store parameter changes after power cycles, it is needed to execute the "writeValues" function. If not, when the XBee is powered off, values do not remain in the module's memory.
- The battery has to be connected.
- This example can be executed in Waspmote v12

    from the coordinator. After reseting the network a new PAN ID
    is set.
