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.

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).

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 module. 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 simul taneously.)
10. Hardware design
It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible, and
the module needs to be reliably grounded.
；
Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse
connection may cause permanent damage to the module
；
Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the
maximum value the module will be permanently damaged
；
Please check the stability of the power supply, the voltage can not be fluctuated frequently
