» 900 04a: Send broadcast

This program shows how to send packets with XBee-900 modules. Broadcast address (0x000000000000FFFF) is specified as destination address

Required Materials

1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x XBee-900

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, channel, encryption mode)
