4.11.1 Wake up the ME from SLEEP modeA wake-up event is any event that switches off the SLEEP mode and causes the ME to return to fullfunctionality. In short, it takes the ME back to <strong>AT</strong>+CFUN=1.Definitions of the state transitions described in Table 6:Yes = ME exits SLEEP mode.No = ME does not exit SLEEP mode.Table 6: Wake-up events in NON-CYCLIC and CYCLIC SLEEP modeEventFrom SLEEP mode<strong>AT</strong>+CFUN=0 to<strong>AT</strong>+CFUN=1From SLEEP mode<strong>AT</strong>+CFUN=5 or 6 to<strong>AT</strong>+CFUN=1Ignition line No No/RTS0 (falling edge) Yes NoUnsolicited Result Code (URC) Yes YesIncoming voice or data call Yes YesAny <strong>AT</strong> command(incl. outgoing voice or data call, outgoingSMS)Incoming SMS depending on modeselected by <strong>AT</strong>+CNMI:<strong>AT</strong>+CNMI=0,0 (= default, no indicationupon receipt of SMS)<strong>AT</strong>+CNMI=1,1 (= displays URC uponreceipt of SMS)GPRS data transferNot possible(UART disabled)NoYesNot possible(UART disabled)NoNoYesNoRTC alarm Yes Yes<strong>AT</strong>+CFUN=1Not possible(UART disabled)YesRecommendation:• In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up the ME and return to fullfunctionality. This is a useful approach because, in this mode, the <strong>AT</strong> interface is not accessible.Page 79 of 207
