4.1. Configuration Mode
When HF-LPB power up, it will default works as transparent transmission mode, then user can switch
to configuration mode by serial port command. HF-LPB UART default parameters setting as below
figure,
Figure 34. HF-LPB 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.
¾
UART input “+++”, after module receive “+++”, and feedback “a” as confirmation.
¾
UART input “a”, after module receive “a” and feedback “+ok” to go into AT+
instruction set configuration mode.
Figure 35. 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).
