XBee/XBee PRO DigiMesh 2.4 Getting Started Guide

The XBee/XBee PRO DigiMesh 2.4 modules support low-cost, low-power, peer-to-peer or wireless
mesh networks. The XBee modules provide reliable delivery of data between remote devices.
This guide shows you how to set up an XBee mesh network using the DigiMesh protocol, send data
between your XBee modules, and adjust your XBee module settings.

DigiMesh networks

DigiMesh is a proprietary networking topology for use in wireless end-point connectivity solutions. It
supports advanced networking features including sleeping routers and dense mesh networks.
DigiMesh supports multiple network topologies such as point-to-point, point-to-multipoint, and mesh
networks. With support for sleeping routers, DigiMesh is ideal for power-sensitive applications that
rely upon batteries or power-harvesting technology.
DigiMesh contains the following features:
Self-healing: Any node may enter or leave the network at any time without causing the
n
network as a whole to fail.
Peer-to-peer architecture: No hierarchy and no parent-child relationships are needed.
n
Easy to use: Mesh networking is simplified because it does not require hierarchy or parent-child
n
relationships.
Quiet: Routing overhead is reduced by using a reactive protocol similar to Ad-hoc On Demand
n
Distance Vector routing (AODV).
Route discovery: Routes are discovered and created only when needed, eliminating the need to
n
maintain a network map.
Selective acknowledgments: Only the destination node will reply to route requests.
n
Reliable: Acknowledgments confirm successful delivery of data.
n
Sleep modes: Supports low-power sleep modes with synchronized wake up as well as variable
n
sleep and wake times.

Synchronous sleeping network

One advantage of DigiMesh is that it allows all nodes in the network to both route data and enter low-
power states. The synchronous sleep feature makes it possible for all nodes in the network to
