At+Cfun Set Phone Functionality - Siemens TC37 Module At Command Reference

AT Command Set

4.9 AT+CFUN Set phone functionality

The AT+CFUN command serves to query or select the level of functionality <fun> of the ME. Level
"full functionality" is where high current is drawn, depending on the operating mode, e.g. IDLE, TALK
or DATA mode. "Minimum functionality" is where minimum power is drawn, referred to as SLEEP
mode.
For detailed information on the various operating modes and the current consumption please see the
"Hardware Interface Description" supplied with your GSM engine.

0 Minimum functionality (SLEEP mode)
AT+CFUN=0 disconnects any call in progress. The SLEEP
mode starts after remaining network activities are
terminated. While SLEEP mode is in effect, the AT interface
is not accessible. Consequently, once you have issued
AT+CFUN=0, do not send further characters. Otherwise
these characters remain in the input buffer and may delay
the output of an URC (see pg. 185, e.g. "RING").
1 Full functionality (IDLE, TALK, DATA, mode)
0 The <rst> parameter can only be used if +CFUN=1. 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.
Therefore, you are required to use AT+CPIN again. 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 2.46.1
