Chengdu Ebyte Electronic Technology Co., Ltd.
Automatic resend: In the on-demand (unicast) mode, the device will automatically resend when it fails to send to the

next node, and the number of re-sends for each message is 2 times.
Automatic routing: the module supports the network routing function; the router and the coordinator carry the network

data routing function, and the user can carry out multi-hop networking .
Open and close network networking: The coordinator controls the opening or closing of the network. During the period

of time when the network is open, devices that comply with the ZigBee3.0 standard can join the network. After the
network is closed, no device can join. After the coordinator opens the network, if there is no operation to close it, it will
automatically close after 180 seconds.
One-click network addition: nodes do not need to set PANID and channel, but only need to trigger network addition

within the window time when the coordinator opens the network.
Automatic channel and PANID: The coordinator automatically creates a network on the optimal channel, and

automatically assigns a PANID to avoid duplication with other coordinators.
Automatically obtain the MAC address: the coordinator can obtain the MAC address and short address of the node when

the node is connected to the network, without further processing on the device side.
Multi-type data communication: support network-wide broadcast, multicast and on-demand (unicast) functions; also

support several transmission modes in broadcast and on-demand (unicast) modes.
Address search: users can find the corresponding short address according to the MAC address (unique, fixed) of the node

that has joined the network, and can also find the corresponding long address of each node in the network according to
the short address of the node;
Data security: Integrating ZIGBEE 3.0 security communication standard, the network contains multi-level security keys;

Channel change: support 16 channels such as 11~26 (2405~2480MHZ), different channels correspond to different

frequency bands.
Network PAN_ID change: Any switching of network PAN_ID, user can customize PAN_ID to join the corresponding

network or automatically select PAN_ID to join the network.
Serial port configuration: The module has built-in serial port commands, and users can configure (view) the parameters

and functions of the module through serial port commands;
One-key recovery of baud rate: When the current baud rate of the radio is forgotten, the baud rate of the radio can be

restored to 115200bps through the SMART key.
Serial port baud rate change: users can set the baud rate by themselves, up to 115200 bps , the default number of bits is 8

bits, stop bit is 1 bit, and there is no parity bit.
Module reset: The user can reset the module through the serial port command.

restore the factory settings of the module through serial port commands or the "SMART" key.

Over-the-Air Configuration: Users can remotely configure other devices in the network using air configuration

commands.
Multiple command formats: users can use hexadecimal format commands and AT commands to configure and control the

module, realize networking, set transparent transmission, control lights and other operations.
Possess a national invention patent certificate, invention name: a ZigBee3.0-based wireless transparent transmission

module interconnection method, patent number: ZL 2019 1 1122430.X
