and prevent monitoring. Users can change the network key by themselves. Only devices with the same network key
can start normal networking communication.
 Support UART configuration: Module has built-in UART commands, the user can configure (view) the parameters
and functions of module via UART command .
 Communication for various types of data: Support broadcasting, multicasting and unicasting in the entire network.
In the broadcast and unicast mode, it also supports several transmission methods
 Multi-mode selection: support through mode, semi-through mode, protocol mode, three working modes, user can
switch freely
 Change channel: It supports change of 16 channels ranging from 11 to 26
（
2405~2480MHZ
）
, different channels
have different frequency.
 Change network PAN_ID: Free switch of network PAN_ID. Users can define PAN_ID to join the corresponding
network by themselves or automatically select PAN-ID to join the network.
 Change UART baud rate: Users can set baud rate by themselves which can be as high as 1M, it is 8 bits by default
without parity bit.
 Search short address: Users can find out corresponding short address according to the (unique and fixed) MAC
address of module that already joined network.
 GPIO control:Local/remote gpio control function，there are 10 gpio for users to select.
 Pwm control :Local/remote pwm control function，there are 5 pwm channels for users to select.
 ADC control:Read local/remote adc
，
there are 7 adc channels for users to select.
 Command format switch: The module supports AT command and HEX command for users’ easy configuration and
switch.
 Module restore:Users can restore the module via UART commands.
 Onekey recovery of baud rate: The module supports onekey recovery of baud rate when users forget the baud rate.
The baud rate is 115200(default).

Recover factory setting:Users recover the factory setting via UART commands.
1.3 ZigBee introduction
ZigBee technology is a two-way wireless communication technology that features short range, low complexity,low
power, low speed and low cost.
There are three types of logical devices in the ZigBee network: Coordinator, Router, and End-Device. The ZigBee
network consists of a Coordinator and multiple routers and End-Devices.
These devices own the following functions:
（1）Coordinator
As the first device in the network, the coordinator is responsible for starting the entire network. . The
coordinator selects a channel and a network ID (also known as the PAN ID, the Personal Area Network ID), and
then starts the entire network.
Coordinators can also be used to help establish bindings between security layer and application layer in the network.
Note that the role of the coordinator mainly involves the network startup and configuration. Once these are done,
the coordinator works like a router (or disappears /go away). Due to the distribution characteristics of the
ZigBee network itself, the operation of the entire network is not dependent on the existence of the coordinator.
（2）Router
