3.3.2.5 Wake up MC45 from SLEEP mode

A wake-up event is any event that switches off the SLEEP mode and causes MC45 to return
to full functionality. In short, it takes MC45 back to AT+CFUN=1.
Definitions of the state transitions described in Table 10:
Yes = MC45 exits SLEEP mode.
No = MC45 does not exit SLEEP mode.

Event
Ignition line
/RTS0 or /RTS1 (falling edge) Yes
Unsolicited Result Code
(URC)
Incoming voice or data call
Any AT command
(incl. outgoing voice or data
call, outgoing SMS)
Incoming SMS depending on
mode selected by AT+CNMI:
AT+CNMI=0,0 (= default, no
indication of received SMS)
AT+CNMI=1,1 (= displays
URC upon receipt of SMS)
GPRS data transfer
RTC alarm
AT+CFUN=1
Recommendation:
·
In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up MC45 and return
to full functionality. This is a useful approach because, in this mode, the AT interface is
not accessible.
