900HP 02: Send packet

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 MicroUSB wire 1 x XBee-PRO 900HP

Notes

- The battery has to be connected. - This example can be executed in Waspmote v15
