3.2.1.1 Switch transparent mode to command mode
There are 2 steps from transparent mode to command mode :
Enter "+++" on the UART port, and the module will return a confirmation code
"a" after receiving "+++";
Enter the confirmation code "a" on the UART port. After receiving the
confirmation code, the module returns to "+ok" to confirm and enter the command
mode.
Pic 45 from transparent mode to command mode
<Description>:
When you enter "+++" and the confirmation code "a", the serial port is not echoed,
as above picture.
Entering "+++" and "a" needs to be completed within a certain period of time to
reduce the probability of entering the command mode by mistake during normal
operation. Specific requirements are as follows:
Enter
“+”
Enter
“+” Enter“+”
Enter
“a”
echoed
“a”
In the command mode, the module can be set,queried and restarted by the AT+
command under the UART port.. It can also return to the transparent transmission
mode through the AT+ command. The AT+ instruction details pls refer to next section.
3.2.2 AT+ Command instruction
The AT+ command can be input directly through a serial port debugger like
HyperTerminal, or be programmed. As shown in the figure below, through the
SecureCRT tool, AT+H is a help command that lists all the commands and
instructions.
