This example shows how to receive packets with XBee modules
Required Materials
1 x Waspmote
1 x Battery
1 x MiniUSB wire
1 x XBee-Digimesh
Notes
- There must be a XBee module sending packets
- Both XBee modules must be configured with the same network parameters (PANID, channel and encryption mode)
- The battery has to be connected.
- This example can be executed in Waspmote v12
