Self-Adaption Baudrate; Web Io; Keepalive; Multiple Sta Parameters - Jinan USR IOT Technology WIFI232-A User Manual

web, build joint function of ID/MAC for the first time, and each data with the function of ID/MAC
are disabled by default.
Note: the function of the upload MAC supported in V5.01.14 and above version.

4.8.3 Self-adaption Baudrate

This feature, please cooperate with our company's virtual serial port software use.
Use a serial port connected module, and use the at command "at + AABR = on" open this
function and restart.In the USR - VOCM software "synchronous baud rate (RFC2217 similar)" is
selected, the following figure.
Specific setup process, please refer to the AT command section(5.2.2.2.39).
In this way, the module of baud rate will be as the USR-VCOM to change at any time, and don't
have to restart the module.If restart the module, baud rate and will come back to before.

4.8.4 WEB IO

This function only work for "GPIO mode".
When the module is in the "GPIO mode", enter the Webpage in "WEB IO", you can click on the
corresponding button to control module pin level. Without the need to download and install app,
any platform, any equipment, as long as you can into the built-in Webpage of module through the
browser built-you can control module pin of IO.

4.8.5 Keepalive

V4.02.10. USR13 and above version of the firmware added keepalive when the TCP connection
mechanism, so when the module of network anomalies, timely diagnose abnormal to the network
and disconnect, when the network has resumed after, and just in time to connect to the server.

4.8.6 Multiple STA parameters

This function based on V4.02.10 D.U SR18 and above version of the firmware, in the sta mode, if
can network signal is too low, it will automatically switch to the other AP network (switching
network automatically restart).
This feature provides a signal threshold, when the current network signals is lower than the
critical value, the module of automatic switching network and restart.If the signal value is set to
100, the module will not switch network.Even if the current network signal is not the current
network will always search, not heavy to other networks.
The function of the specific Settings page refer to section 5.1.4.
