AT Command Set
<rst>
Reference Note
GSM 07.07
· If SLEEP mode (<fun>=0, 5, or 6) is activated while a circuit-switched call is
· Please keep in mind that power saving works only while the ME is registered
· To check that power saving is on, you can query the status with AT+CFUN?,
· In Multiplex mode, the CFUN profile is shared by all multiplexer channels.
Example 1 To check the level of functionality use the read command:
AT+CFUN?
+CFUN: 1
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 5or 6.
AT+CFUN?
+CFUN: 5
MC35_ATC_01_V05.00
1 Full functionality.
If the ME is in one of the two CYCLIC SLEEP modes you
can issue AT+CFUN=1 to stop power saving and return to
full functionality. Keep in mind that, unlike the reset
command described below, this action does not restart the
ME but only changes the level of functionality. See
parameter <rst> for details on the reset.
5 CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled during
paging. If characters are recognized on the serial interface,
the ME stays active for 2 seconds after the last character
was sent or received.
6 CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled during
paging. If characters are recognized on the serial interface,
the ME stays active for 10 minutes after the last character
was sent or received.
0 The <rst> parameter can only be used if the serial interface
is enabled. Due to the command syntax, you need to enter
<fun>, followed by <rst>, where <fun> is only a placeholder
and has no effect. See examples below.
1 ME resets and restarts to full functionality.
After reset and restart, PIN 1 authentication is necessary
(AT+CPIN). If autobauding is enabled it is recommended to
wait 3 to 5 seconds before entering the first AT command.
For details on autobauding refer to Chapter 2.45.1.
in progress, this call will immediately be terminated.
to the GSM network. If you attempt to activate one of the SLEEP modes
while the ME is deregistered, the selected <fun> level will be set, but power
saving does not take effect. Furthermore, in order to accept incoming calls,
SMS or network related URCs in SLEEP mode the ME must be registered
when it enters the SLEEP mode.
if you have chosen CYCLIC SLEEP mode. If available, you can take advan-

[1]. The LED stops flashing once the module starts power saving.
