The parameter can only be used if the serial interface is enabled.
Due to the command syntax, you need to enter parameter
<fun>, followed by <rst>, where <fun> is only a
placeholder and has no effect. See examples below.
[0] Placeholder for
<fun> as stated above.
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 recom-
mended to wait 3 to 5 seconds before entering the first AT command. For
details on autobauding refer to chapter "4.10.1".
Notes
• In Multiplex mode, the CFUN profile is shared by all multiplexer channels.
• If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode with
AT+CFUN=<fun>. The
best approach to properly control SLEEP mode in this case is to issue the PSC messages described in [4],
chapter "Power saving control".
• When a circuit-switched call is in progress,
<fun>=7 or 8 can be activated without terminating the call. How-
ever, setting
<fun>=0, 5 or 6 during a circuit-switched call immediately disconnects this call.
• Please keep in mind that power saving works properly only when PIN authentication has been done. If you
attempt to activate power saving while the SIM card is not inserted or the PIN is not correctly entered, the
selected
<fun> level will be set, though power saving does not take effect. For the same reason, power sav-
ing cannot be used if TC35i operates in Alarm mode. 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.
• To check whether power saving is on, you can query the status with the read command AT+CFUN? only if
the module is in full functionality mode or in CYCLIC SLEEP mode. If available, you can also take advantage
of the status LED controlled by the SYNC pin (see
AT^SSYNC and [2]). With AT^SSYNC you can select differ-
ent modes of LED signalization during SLEEP modes (see 16.6.1 for details). However, the module can wake
up temporarily from power saving without leaving its CYCLIC SLEEP mode (without changing +CFUN
"
<fun>"), e.g. for a network scan after a loss of radio coverage, or after receipt of serial data during CYCLIC
SLEEP mode. During this "temporary wakeup state" the LED will operate as if the ME was in full functionality
mode.
• Recommendation: In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up the ME and return
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
<fun> is set to 5, 6, 7 or 8.
