1. Module introduction
1.1 Introduction to ZigBee
ZigBee technology is a short-range, low-complexity, low-power, low-speed, low-cost two-way wireless
communication technology.
There are three logical device types in the ZigBee network: Coordinator (coordinator), Router (router) and
End-Device (terminal device). A ZigBee network consists of a Coordinator, multiple Routers and multiple
End_Devices.
The functions of each type of equipment are as follows:
(1) Coordinator (coordinator)
The coordinator is responsible for starting the entire network. It is also the first device of the network. The
coordinator selects a channel and a network ID (also called PAN ID, Personal Area Network ID), and then starts
the entire network.
The coordinator can also be used to assist in establishing bindings between the security layer and the
application layer in the network.
Note that the role of the coordinator primarily involves the startup and configuration of the network. Once
this is all done, the coordinator works like a router (or goes away). Due to the distributed characteristics of the
ZigBee network itself, the subsequent operation of the entire network does not depend on the existence of the
coordinator.
(2) Router (router)
The main functions of the router are: to allow other devices to join the network, multi-hop routing and to
assist in communication with its own battery-powered son terminal device.
Usually, a router is expected to be active all the time, so it must be powered by mains power. But when using
the network mode of the tree group, the routing is allowed to operate once at a certain period of time, so that it can
be powered by the battery.
(3) End-Device (terminal equipment)
The end device has no specific responsibility for maintaining the network structure, it can sleep or wake up,
so it can be a battery powered device.
