Explanation: This program shows how to set the node identifier. Once the node has been configured is ready to receive.
Required Materials
1 x Waspmote
1 x Battery
1 x MiniUSB wire
1 x XBee-Digimesh module
Notes
- This example belongs to a two-code example. This is the receiving part.
- All XBee modules must be configured with the same network parameters (PANID and encryption mode)
- The battery has to be connected.
- This example can be executed in Waspmote v12
