to full functionality. This is a useful approach because, in this mode, the AT interface is not accessible.
Examples
EXAMPLE 1
To check the level of functionality use the read command:
Remember that the AT interface is not accessible in NON-CYCLIC SLEEP mode. Consequently, the read
command is only useful when the ME is set to full functionality or, when
is set to 5, 6, 7, 8 or 9.
EXAMPLE 2
To set the ME to NON-CYCLIC SLEEP mode enter
When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME
wakes up to full operation.
Note that the URC used in this example will appear only, if
=1,1 was configured before.
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:
AT+CFUN?
+CFUN: 1
Default mode after ME was restarted
AT+CFUN?
+CFUN: 5
CYCLIC SLEEP mode
AT+CFUN=0
OK
+CMTI: "SM",5
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
¹ 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.
