» 868 02: Send packets

This program shows how to send packets to a gateway indicating the MAC address of the receiving XBee module

Required Materials

1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x XBee-868

Notes

* This example belongs to a two-code example. This is the sending part.
* Both XBee modules must be configured with the same network parameters (PANID and encryption mode)
