When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME
wakes up to full operation.
After this, you may want to verify the operating status:
EXAMPLE 3
To stop CYCLIC SLEEP mode and return to full functionality:
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:
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.
Table 2.3: Wake-up events in NON-CYCLIC and CYCLIC SLEEP modes
+CMTI: "SM",5
Note that the URC used in this example will appear only, if
AT+CNMI
=1,1 was configured before.
AT+CFUN?
+CFUN: 1
Indicates that ME has entered full functionality mode.
AT+CFUN?
+CFUN: 5
OK
AT+CFUN=1
OK
AT+CFUN=1,1
or alternatively, AT+CFUN=0,1 or 5,1 or 6,1 or 7,1 or 8,1 or 9,1
OK
^SYSSTART
The ^SYSSTART URC confirms that the ME has been rebooted. Note
that ^SYSSTART appears only if
AT+IPR
≠ 0. If the ME is in autobaud
mode, it is recommended to wait 3 to 5 seconds before entering the first
AT command. Remember to enter the SIM PIN after restart.
