» 802 01: Configure XBee

This program shows how to configure basic XBee parameters in order to communicate between different XBee devices using the same network.

Required Materials

1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire

Notes

* The XBee module must be configured to the default baud rate (BD=7) and AP parameter (AP=2).
* 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.
