In the virtual serial port software, select "synchronous baud rate (class
RFC2217)", and use the at command "AT+AABR=on" to open the module's adaptive
baud rate function and restart. As shown below:
In the picture, the virtual serial port synchronizes the baud rate. The baud rate of
the module changes with the baud rate of the virtual serial port at any time, and the
module does not need to be restarted. If the module is restarted, the baud rate will
return to the previous baud rate.
2.7.4 KeepAlive Function
When the TCP connected, the keep-alive mechanism is added. Therefore,
when the network of the module is abnormal, the network abnormality can be judged
and disconnected in time. When the network is restored, the network can also be
connected to the server in time.
2.7.5 Multi-STA Function
Added multiple SAT network setting function. In STA mode, if the connected
network has a low signal, it will automatically switch to other AP networks (it will
automatically restart when switching networks).
This function provides a signal threshold that automatically switches to the
network and restarts when the current network signal is below the signal threshold. If
the signal value is set to 100, the module will not switch to networks. Even if the
current network signal is not available, it will always search the current network and
will not reconnect to other networks.
The specific settings page of this function,Please refer to section 2.5.3 chapter.
This function can also be set by the AT command, refer to section
3.2.2.2.49-3.2.2.2.55 chapters.
2.7.6 Domain name backup and smart STA
After the domain name backup function is enabled, the IP address of the
domain name will be automatically saved when the module is connected to the
server of the domain name. If the server can’t be connected over five minutes
(Including the IP address cannot be resolved or the resolved IP address cannot be
connected.) it will automatically enable the alternate IP to connect.
This function can be turned on/off in the web page or AT command (AT+IPBUP).
Smart STA function. If the module is in STA mode and has not been connected
to the router for five minutes, the module will automatically start its own AP function
and connect the router every 80 seconds at a later time. This function allows the
user to continue to control the module or set the parameters of the module wireless.
This feature is always off.
