Communication / 802.15.4:

» 802 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
2 x XBee-802.15.4 modules (emitter & receiver)

Notes

- Both XBee-802.15.4 modules must be configured with the same network parameters (PANID, channel and encryption mode)
- Attention to the destination MAC address which MUST be modified by the user
- The battery has to be connected.
- This example can be executed in Waspmote v12 and Waspmote v15
