Wake Up The Me From Sleep Mode; Table 2.3: Wake-Up Events In Non-Cyclic And Cyclic Sleep Modes - Siemens Brodersen MC55 AT Command Manual

When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME
wakes up to full operation.
+CMTI: "SM",5
After this, you may want to verify the operating status:
AT+CFUN?
+CFUN: 1
EXAMPLE 3
To stop CYCLIC SLEEP mode and return to full functionality:
AT+CFUN?
+CFUN: 5
OK
AT+CFUN=1
OK
Remember that this approach is not applicable to the NON-CYCLIC SLEEP mode (since the serial interface
is disabled). The NON-CYCLIC SLEEP mode ends with the first wake-up event.
EXAMPLE 4
To reset and restart the ME:
AT+CFUN=1,1
OK
^SYSSTART
2.8.1

Wake up the ME from SLEEP mode

A wake-up event is any event that causes the ME to draw more 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.

that ^SYSSTART appears only if
