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:

AT+CFUN?
+CFUN: 1	Default mode after ME was restarted

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 <fun> is set to 5, 6, 7, 8 or 9.

AT+CFUN?
+CFUN: 5	CYCLIC SLEEP mode

EXAMPLE 2

To set the ME to NON-CYCLIC SLEEP mode enter

AT+CFUN=0

OK

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

Note that the URC used in this example will appear only, if AT+CNMI=1,1 was configured before. After this, you may want to verify the operating status:

AT+CFUN?
+CFUN: 1	Indicates that ME has entered full functionality mode.

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	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.
