Example
：
AT+IOCFG=0
16
AT+DFCFG Restore the default parameter
AT+DFCFG
Description
：
Null
Restore the default parameter
Example
：
AT+DFCFG
17
AT+RSTART Device Restart
AT+RSTART
Description
：
Null
Device Restart
Example
：
AT+RSTART
18
AT+ECHO Sets up the AT instruction to turn off the back display
AT+ECHO=Value
Description:
Value:0 or 1
1
：
Close the echo
0
：
Open the echo
Example
：
AT+ECHO=1
Note
：
This setting only applies when the power is turned on. After the restart, the default settings are restored and the echo is
enabled by default.
19
AT+VER Reding the version number
AT+VER
Description:
Example
：
AT+VER
20
AT+CLINFO Clearing network information
AT+CLINFO
Description:
Example
：
AT+CLINFO
Note: The network cannot be re-established after the module is cleared (this command can clear all the information when the
number of coordinator node devices reaches 50).
21
AT+TLCFG Setting/Querying the concurrency performance parameter (reboot valid)
AT+TLCFG=
？
Description:
Gets the concurrency performance parameter
Response
：
TLCFG:0
AT+TLCFG=value
Description:
Value:0~3
0
：
Low concurrency
1
：
Medium concurrency
2
：
High concurrency
3
：
Highest concurrency
Example: AT+ TLCFG =0 (Note: This parameter is mainly used to configure the concurrency performance of the modem. That is,
when various nodes concurrently transmit data, the maximum number of nodes is supported. The higher the performance, the greater
the number of concurrent systems, but the delay in sending data. The average power consumption of the nodes will increase; the lower
the performance, the higher the real-time performance of the data sent by the nodes, but the data may be lost when the environment
has large interference or multiple nodes transmit simultaneously.
8.
Note
In sleep mode, The serial port parameters are 115200, 8N1( fixed). If the user forget the current baud rate, t hey can
use this At command to reconfigure.
After the node is associated with the coordinator, the node information will be saved, and the information will still
exist after the node is disconnected from the network, this mechanism has two advantages:
When the same node joins the network established by the coordinator, the network access speed will be increased.
After a node enters the network, the short address will never change as long as the current network exists.
