5.9.6 Wake up I56/I56i from SLEEP mode
A wake-up event is any event that causes the module to draw current.
Depending on the selected mode the wake-up event either switches SLEEP
mode off and takes I56/I56i back to
AT+CFUN=1
, or activates I56/I56i
temporarily without leaving the current SLEEP mode.
Definitions of the state transitions described in table 18 below:
Quit =
I56/I56i exits SLEEP mode and returns to
AT+CFUN=1
.
Temporary =
I56/I56i becomes active temporarily for the duration of the
event and the mode-specific follow-up time after the last
character was sent or received on the serial interface.
No effect =
Event is not relevant in the selected SLEEP mode. I56/I56i
does not wake up.
