+CFUN - Set Phone Functionality
4 - disable both TX and RX
5 - mobile full functionality with power saving enabled
<rst> - reset flag
0 - do not reset the ME before setting it to <fun> functionality level
Note: issuing AT+CFUN=4[,0] actually causes the module to perform either
a network deregistration and a SIM deactivation.
Note: if power saving enabled, it reduces the power consumption during the
idle time, thus allowing a longer standby time with a given battery capacity.
Note: to place the module in power saving mode, set the <fun> parameter
at value = 5 and the line DTR (RS232) must be set to OFF. Once in power
saving, the CTS line switch to the OFF status to signal that the module is
really in power saving condition.
During the power saving condition, before sending any AT command on the
serial line, the DTR must be enabled and it must be waited for the CTS
(RS232) line to go in ON status.
Until the DTR line is ON, the module will not return back in the power saving
condition.
Note: the power saving function does not affect the network behavior of the
MODULE, even during the power save condition the module remains
registered on the network and reachable for incoming calls or SMS. If a call
incomes during the power save, then the module will wake up and proceed
normally with the unsolicited incoming call code
AT+CFUN? Read command reports the current setting of <fun>.
AT+CFUN=? Test command returns the list of supported values for <fun> and <rst>.
Reference 3GPP TS 27.007
3.5.4.4.3 Enter PIN - +CPIN
+CPIN - Enter PIN
AT+CPIN=<pin>
[,<newpin>]
Set command sends to the device a password which is necessary before it
can be operated (SIM PIN, SIM PUK, PH-SIM PIN, etc.).
If the PIN required is SIM PUK or SIM PUK2, the <newpin> is required.
This second pin, <newpin> will replace the old pin in the SIM.
The command may be used to change the SIM PIN by sending it with both
parameters <pin> and <newpin> when PIN request is pending; if no PIN
request is pending the command will return an error code and to change the
PIN the command +CPWD must be used instead.
Parameters:
<pin> - string type value
<newpin> - string type value.
