DM 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-Digimesh

Notes

- There must be a XBee module listen to receive packets - Both XBee 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
