» 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
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)
- This example can be executed in Waspmote v12 and Waspmote v15
