MC55 AT Command Set
2.8 AT+CFUN

AT+CFUN Set phone functionality
This command serves to control the functionality level of the ME. It can be used to reset the ME, to choose one
of the SLEEP modes or to return to full functionality.
Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizes
the current consumption. SLEEP mode falls in two categories:
•
NON-CYCLIC SLEEP mode
•
and CYCLIC SLEEP modes, selectable as
NON-CYCLIC SLEEP mode permanently blocks the serial interface. The CYCLIC SLEEP mode, however, is a
dynamic process which alternatingly enables and disables the serial interface. The major benefit of all CYCLIC
SLEEP modes is that the serial interface remains accessible and that, in intermittent wake-up periods, characters
can be sent or received without terminating the selected mode. The best choice is using
since in these modes MC55 automatically resumes power saving, after you have sent or received a short mes-
sage or made a call.

patibility with earlier releases. In all CYCLIC SLEEP modes, you can enter
MC55 and take it back to full functionality. Please refer to section
the different ways of waking up the module.

hardware flow control. This is necessary since the CTS signal is set/reset every time when the ME listens to a
paging message from the base station. This is the way how the module indicates to the application when the
UART is active. For detailed information on the timing of the CTS signal refer to [2]. The default setting of hard-
ware flow control is

If both interfaces ASC0 and ASC1 are connected, hardware flow control must be set in either application.
