This program shows how to send packets with XBee-802.15.4 modules. The destination address is set as a 16-bit network address.
Required Materials
1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x XBee-802.15.4 module
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)
- The battery has to be connected.
- This example can be executed in Waspmote v12 and Waspmote v15
