Characteristics
Description
1
Role switching
The user can use the serial port command to let the device switch between the three types of coordinator,
router and terminal.
2
Automatic networking
Supports power-on automatic networking. The coordinator automatically builds up the network by power,
and the terminals and routers automatically search and join the network.
3
Network self-healing
Lost network automatic reconnection function. The network intermediate node is lost, and other networks
automatically join or maintain the original network. (The isolated node automatically joins the original
network, and the non-isolated node maintains the original network.)
The coordinator is lost and there are non-isolated nodes in the original network. The coordinator can join
the network again or the coordinator of the original PAN_ID set by the same user can join the original
network.
5
Data retention time
setting
In the state of the coordinator and router, the user can set the data storage time and use it in conjunction
with the terminal in the sleep mode to save the data of the terminal device and send the data to the terminal
after the terminal wakes up.
Save up to 3 pieces of data, if it is exceeded, automatically clear the first data! After the data is saved, the
data heap is automatically cleared.
6
Automatic resend
In single broadcast(point transmission) mode, when the device fails to send to the next node, it
automatically retransmits every message three times.
7
Automatic routing
The module supports network routing function. Routers and coordinators carry network data routing
functions, and users can form multi-hop networks.
8
Support encryption
protocol
The module uses AES 128-bit encryption to change network encryption and anti-listening. Users can
change the network key by themselves, and the devices with the same network key can communicate
normally.
9
Support Serial Port
Configuration
Module built-in serial instructions, users can configure (view) the parameters and functions of the module
through the serial instructions.
10
Multi-type data
communication
Supports all-network broadcast, multicast and on-demand (single broadcast) functions. Several
transmission methods are also supported in broadcast and single broadcast modes, please refer to the
details.
11
Multiple working mode
selection
It supports three working modes: transparent transmission mode, semi-through mode, protocol mode, and
user can switch freely.
12
Channel change
Supports 16 channel changes from 11 to 26 (2405~2480MHZ), and different channels correspond to
different frequency bands.
13
Network PAN_ID change
Any switch of the network PAN_ID, the user can customize the PAN_ID to join the corresponding
network or automatically select the PAN_ID to join the network.
14
Serial Port Baud Rate
Change
The user can set the baud rate up to 1M, default digit is 8 bits, stop bit is 1 bit, no parity bit.
15
Short address collection
The user can find the corresponding short address according to the module MAC address (unique, fixed)
that has joined the network.
16
Instruction format
switching
This module supports AT command and HEX command, which are easy to configure.
17
Module reset
The user can reset the module through the serial port command.
18
One-click Recovery Baud
Rate
This module supports one-button recovery of baud rate. This function can be used when the user forgets
the baud rate. The default baud rate is 115200.
19
Restore factory settings
Users can restore the factory settings of the module through serial port commands.
