Execute command
Read command
AT+CFUN? reports the power saving status in the form:
+CFUN: <fun>
where
<fun> - power saving status
1 - power saving disabled
5 - power saving enabled
Note: The phone functionality remains always FULL.
Write command
AT+CFUN=<fun>
Enables/disables the power saving function.
If enabled it reduces the power consumption during the idle time, thus
allowing a longer standby time with a given battery capacity.
Parameters:
<fun>: is the power saving function mode
1 - Mobile full functionality with power saving disabled (default)
5 - Mobile full functionality with power saving enabled
Note: To place the telephone 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 telephone 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 telephone will not return back in the
power saving condition.
Note2: The power saving function does not affect the network behavior
of the GM862-GPRS, 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
