Wake Up The Me From Sleep Mode; Table 7: Wake-Up Events In Non-Cyclic And Cyclic Sleep Mode - Siemens MC35 Command Set

AT Command Set

4.11.1 Wake up the ME from SLEEP mode

A wake-up event is any event that switches off the SLEEP mode and causes the ME to return to full
functionality. In short, it takes the ME back to AT+CFUN=1.
Definitions of the state transitions described in Table 7:
Yes = ME exits SLEEP mode.
No = ME does not exit SLEEP mode.

Recommendation:
· In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up the ME and return to full
functionality. This is a useful approach because, in this mode, the AT interface is not accessible.
