MC55 AT Command Set
2.8 AT+CFUN
2.8.1
Wake 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
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.
