1.3 Device Type Introduction

There are three logical device types in ZigBee network: Coordinator (coordinator), Router (router), End-Device (non-sleep

terminal) and Sleep-End-Device (sleep terminal). The ZigBee network consists of a Coordinator, multiple Routers and multiple

End_Devices (its terminal nodes can be divided into sleeping terminals and non-sleeping terminals).

1.3.1 non-sleep terminal

The main task of the terminal device is to send and receive messages, and other nodes are not allowed to connect to the terminal

device. The non-sleep terminal is always in working state and can receive and send data at any time. The standby current of this device

type is about 4mA, which is used for scenarios with low power consumption requirements.

1.3.2 dormant terminal

The dormant terminal, when there is no data to send and receive, enters the dormant state, and the dormant current is as low as

about 2.5uA.

When you need to send wireless data or perform command operations, you need to send a wake-up frame through the serial port

first. There are three ways to send the wake-up frame (for details, see Section 4.2 Sleep Node Serial Wake-up).

1.3.3 router

It allows other nodes to connect with the routing device to expand the coverage of the network. Its main task is to forward packets,

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 build its own network or join someone else's network, the router is always active, so it must be powered from the mains.

1.3.4 Coordinator

It has the function of establishing and managing the network, controlling whether other nodes are allowed to join the network,

storing network information, and having all the functions of the routing device. Its main tasks are to manage the network, record the

information of sub-nodes, and forward messages. It is necessary to authenticate the terminal authority requesting access to the

network.
