1.3 Device type introduction
There are three types of logical devices in ZigBee Network: Coordinator, Router, End-Device, and Sleep-End-Device.
AZigBee network consists of one Coordinator and multiple Routers and multiple End-Devices (the end nodes can be
divided into Sleep-End-Device and End-Device.
1.3.1 End-Device
The main task of the device is to send and receive messages, and other nodes are not allowed to connect with the
devices. The End-device is always in working state, and can receive and transmit data at any time. The standby current of
this device type is about 4 mA.
1.3.2 Sleep-End-Device
The Sleep-End-Device enters the sleep state when there is no data receiving and sending, and the sleep current is as
low as about 2.5uA.
When wireless data transmission or instruction operation is needed, wake-up frame shall be sent through serial port
first, and the length shall be more than or equal to 25 bytes (it is recommended to wake up with " FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF " 25 bytes of "FF"). The wake-up time lasts for the Uart_holdtime
time, during which the serial port data (configuration command, payload) can be processed. When a frame of serial port
data is successfully received, the wake-up timeout counter will be refreshed, and the wake-up duration will go further by
Uart_holdtime, otherwise the device will go to sleep again. Uart_holdtime defaults to 1000ms and supports HEX
command to change its value.
Sleep terminal wakeup can also be awakened through the function pin WAKE. WAKE defaults to high level. Pull
down the WAKE pin to wake up the module continuously, and release the WAKE pin to restore the default high level and
the module resumes sleep.
When it is necessary to receive data, it is received through periodic wake-up. The longer the wake-up cycle is set,
the later the reception will be. The wake-up cycle must be set less than 30 seconds. If you only need to upload data, you
can set the wake-up cycle to be greater than 30 seconds or longer to reduce power consumption (default is 5 minutes),
such as battery powered sensors.

1.3.3 Router
The other nodes are allowed to connect with the routing device to extend the coverage of the network. The main task
is to forward packets, play the role of relay routing, and have all the functions of the end-device. If one node has multiple
paths to another node, when one of the paths fails, the network automatically adjusts to other optimal paths for
transmission to ensure data arrives. A router can establish its own network or join someone else's network. The router is
always active, so it must be powered by the main power.
1.3.4 Coordinator
The coordinator 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 routing equipment. It’s main
task is to manage the network, record the information of sub nodes, forward messages, and at the same time, the
coordinator needs to identify the authority of the end device requesting access to the network.
1.4 Application
Smart home and industrial sensors；
Security system and positioning system;
Wireless remote control, UAV;
Wireless game remote control;
Health care products；
Wireless voice, wireless headphones；
Meter reading architecture (AMI);

6.Application function and instruction configuration
6.1 Function pin
6.1.1 LINK
LINK pin indicates the current network status, after the device is successfully connected to the network, the current pin is
pulled high. When the device has no network or the parent node is lost, this pin is pulled low. The external device can
query the device network status through the pin level. In coordinator mode,this pin indicates whether the module is
establishing a network normally;
6.1.2 WAKE
The WAKE pin is mainly used to wake up the dormant terminal. It defaults to a high level when it is powered on.
When the pin is externally pulled down, the dormant terminal device will continue to be awakened. When the pin is
released externally, it will return to high level and enter sleep; Sleep time is determined by the duration of the external
pull down of this pin; for non-sleeping devices, this pin is meaningless;

request. ZLL's touch link protocol includes an initiator and a target. The initiator is End-device and Sleep-End-device.
The target is generally a router. When the touch link pin is continuously pulled down for more than 3000ms, the initiator
will send a network establishment or joining request to the target.
6.1.6 UART_BAUD_RESET
UART_BAUD_RESET pin is used to reset the baud rate, The default level is high when the device is powered on.
In any mode, the pin of the module is pulled down for more than 1000ms. The serial port parameters will be restored
to the default 115200 and 8N1.

6.2 Wireless remote configuration function
The module supports remote configuration function. The 2-byte wireless configuration ID is identified by A8 8A by
default. The user can modify the remote configuration ID. When the first two bytes of wireless air data received by the module
are wireless configuration ID, the module judges that the data packet is a remote configuration command and executes the
corresponding command operation. The data packet will not be output through the serial port.
6.3 Touch link Functional application
6.3.1 Touch link Introduction
Touch link belongs to the standard networking mechanism in ZigBee Light Link (ZLL) protocol. Touch link is a
contact connection. When two modules are close to each other within a certain range, touch link is activated by button or
command. A ZigBee communication network is established between the two modules.
The touch link of the ZLL protocol defines an initiator and a target. The primary responsibility of the initiator is to
initiate the touch link process, which is usually defined as the initiator. The target's role is to wait for a nearby touch link
request. If the initiator does not have a network, the target needs to establish a new network. If the initiator has a network,
the target joins the initiator's network. The lower router will be defined as the target. In a typical light control application,
the remote is the end-device initiator and the light is the router target.
6.3.2 Steps of creating a touch link network
(1) First, before the initiator (end-device) initiates a touch link network, if the initiator (end-device) has joined other
networks before,the information of the previous network must be removed to make the network state in the state of no network.
(2)Secondly, the initiator (end-device) initiates a touch link scan request to discover the target person (router)
existing around, and the scanned person is as close as possible to the initiator in scanning process, and the other devices
are far away from the scanning area as much as possible (the threshold of the scanning signal is -40 dBm) , that is,

devices with signal strength greater than -40dBm will be scanned), if scanning more than two target devices will affect
the success rate of touch link
(3) Secondly, after the initiator scans the target device, if it initiates the touch link for the first time, it initiates a
request to create a new network to the target; if the touch link has succeeded before, it initiates the touch link to the target.
Network request.
(4) Finally, the target responds to the initiator's request to create a new network or join the touch link network.
After the above steps, a new ZLL touch link network has been completed. There may only be one initiator in
network, and other nodes are all targets. Before the touch link, the initiator must first clear the previously added network.
During the touch link process, only one device is close to one device at a time. The touch link network can be used
without coordinator and only requires end-device and router, so that the network is simpler and more convenient, and is
widely used in the field of lighting control.
