2.8.1Wake up the ME from SLEEP mode

A wake-up event is any event that causes the ME to draw current. Depending on the selected mode, the wake- up event either switches the SLEEP mode off and takes the ME back to full functionality AT+CFUN=1, or activates the ME temporarily without terminating the selected SLEEP mode.

Definitions of the state transitions described in Table 2.3:

•Quit: ME exits SLEEP mode.

•Temporary: ME 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. The ME does not wake up.
