1.4 Device Type Introduction

There are three logical device types in the ZigBee network: Coordinator (coordinator), Router (router), and End-Device (terminal).
ZigBee network consists of a Coordinator, multiple Routers and multiple Terminals.

1.4.1 Coordinator

It has the function of establishing and managing the network, controls whether other nodes are allowed to join the network, stores
network information, and has all the functions of routing equipment. Its main task is to manage the network, record child node
information, and forward messages. At the same time, the coordinator needs to identify the authority of the terminal requesting
network access. After the coordinator is powered off, the network will not crash
current network.

1.4.2 Router

It allows other nodes to connect with routing devices to expand the coverage of the network. Its main task is to forward messages,
play the role of relay routing, and have all the functions of terminal devices. If there are multiple paths from one node to another node,
when one of the paths fails, the network will automatically adjust to other optimal paths for transmission to ensure data arrival. A
router can set up its own network, or join someone else's, and the router is always active, so it must be powered by mains power.

1.4.3 Terminal

The main task of the terminal device is to send and receive messages, and other terminal nodes are not allowed to connect to the
terminal device. The terminal is always in working condition and can receive and send data at any time.
