C55/C55I AT COMMAND SET VERSION 1.00
Examples
is a useful approach because, in this mode, the AT interface is not
accessible.
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 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.
