» DM 11: Node search

This program shows how to search for a specific node inside the XBee's network. Once the node has been found a packet is sent to this node.

Required Materials

1 x Waspmote
1 x Battery
1 x MiniUSB wire
1 x XBee-Digimesh module

Notes

- It is recommended to turn on another XBee module in order to have some module to be scanned. This module must be set to the node identifier defined in this code.
- The battery has to be connected.
- This example can be executed in Waspmote v12
