Feature
Description
1
Role switch
Users can switch freely between the coordinator, router and end device via UART command.
2
Automatic
Support power-on automatic networking. The coordinator automatically sets up the network, the
3
networking
end device and the router automatically searches and joins the network.
3
Network
self-healing
Automatically reconnect when losing network. When intermediate node in network is lost, other
networks automatically join or maintain the original network. (Isolated nodes automatically join the
original network, non-isolated nodes maintain the original network.)
When the coordinator is lost and non-isolated nodes exist in the original network, the coordinator
can join the network again or coordinator of the original network PAN_ID set by the same user join
the original network.
4
Ultra low power
consumption
The device can be set as low power mode in the end state. Sleep time of the device can be
changed according to the user's using time. The standby power consumption in the low power
mode is less than 2uA. In the father node data storage time, all messages can be received within the
time set by users.
5
Configuration for
data storage
time
When device is in the coordinator and router state, the user can set their own data storage time, and
work with end device in sleep mode to save data for the end device, and sent data to the end device
when it wakes up.
Data saved is up to 3 data packets, if exceeded, it will automatically clear the first data! After the data
is saved, the data heap is automatically cleared.
6
Automatic
retransmission
In unicast mode, the device will automatically retransmit when failed to send to next node, and the
number of retransmission per message is three.
7
Automatic
routing
The module supports network routing. Router and coordinator have network data routing function,
users can conduct multi-hopping networking.
8
Support
encryption
protocol
The module uses AES 128 bit encryption function, can change the network encryption and prevent
monitoring. Users can change the network key by themselves. Only devices with the same network
key can start normal networking communication.
9
Support UART
configuration
Module has built-in UART commands, the user can configure (view) the parameters and functions of
module via UART command .
10
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, please refer to <E18 v1.2
communication protocol> for the details.
11
Change channel
It supports change of 16 channels ranging from 11 to 26（2405~2480MHZ）, different channels have
different frequency.
12
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.
13
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.
14
Search short
address
Users can find out corresponding short address according to the (unique and fixed) MAC address of
module that already joined network.
15
Command
format switch
The module supports AT command and HEX command for users’ easy configuration and switch.
The physical location is P1.6.
16
Module restore
Users can restore the module via UART commands.
17
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), physical location is P1.7.
18
Recover factory
setting
Users recover the factory setting via UART commands.

②.Open host computer software “Zigbee_Setting_V1.1”, select Com port and set baud rate as 115200(default), then
open port;
③.Click read parameter to read corresponding module parameter.
9
④.Select node type as coordinator, write in parameter. Wait the coordinator to start constructing network and users can
check module parameter.
Set network parameter：（when PAN ID is FFFF, it is automatic PAN ID）
Read parameter when network is constructed：
