4. AT+INSTRUCTION INTRODUCTION
4.1. Configuration Mode
When USR-WIFI232-T power up, it will default works as transparent
transmission mode, then user can switch to configuration mode by serial
port command. USR-WIFI232-T UART default parameters setting as below figure,
Figure 30. USR-WIFI232-T Default UART Port Parameters
In configuration mode, user can setting the module through AT+ instruction
set, which cover all web page setting function.
4.1.1. Switch to Configuration Mode
Two steps to finish switching from transparent transmission mode to
configuration mode.

UART input “+++”, after module receive “+++”, and feedback “a” as
confirmation.

UART input “a”, after module receive “a” and feedback “+ok” to go
into AT+ instruction set configuration mode.
Figure 31. Switch to Configuration Mode
Notes:
1. When user input “+++” (No “Enter” key required), the UART port will
display feedback information “a”, and not display input infor++”
as above UART display.
2. Any other input or wrong step to UART port will cause the module still
works as original mode (transparent transmission).
