Power saving begins 10 minutes after the last character was sent or received
over the serial interface.
Example 4 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 5 To reset and restart the ME:
AT+CFUN=1,1
or alternatively, AT+CFUN=0,1 or 5,1 or 6,1
OK
^SSYSTART
The ^SSYSTART URC confirms that the ME has been
rebooted.
Note that ^SSYSTART 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.
After the GSM engine was reset and restarted you are required to enter PIN 1:
AT+CPIN
+CPIN: SIM PIN
OK
