Switch to Configuration Mode
The steps to switch to configuration mode from transparent transmission mode:
➢
U
ART input “+++”, after module receives “+++”, it will feedback “a” as
confirmation.
➢
U
ART input “a” for confirming, after module receives “a”, it will feedback “+ok”
to go into AT+ instruction set configuration mode.
Figure 40 Switch to Configuration Mode
Notes:
When user input “+++” and confirmation “a”, the UART port will not echo
as above
figure. User need to input “+++” and “a” as fast as possible to reduce the probability
that module error to enter configuration mode when it in working mode.
In configuration mode, user can use AT+ instruction on UART port to setting,
inquiry or restart the module. User can also use AT+ instruction to back to transparent
transmission mode.
