2.9AT+CFUN Set phone functionality

The AT+CFUN 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 <fun>=0

•and CYCLIC SLEEP modes, selectable as <fun>= 7 or 9.

NON-CYCLIC SLEEP mode permanently blocks the serial interface. The benefit of the CYCLIC SLEEP mode 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. This allows the ME to wake up for the duration of an event and, afterwards, to resume power saving. Please refer to Section 2.9.1, Wake up the ME from SLEEP mode for a summary of all SLEEP modes and the different ways of waking up the module.

For CYCLIC SLEEP mode both the ME and the application must be configured to use hardware flow control. This is necessary since the CTS signal is set/reset every 0.9-2.7 seconds in order to indicate to the application when the UART is active. The default setting of hardware flow control is AT\Q0 which must be altered to AT\Q3. For use after restart you are advised to add it to the user profile saved with AT&W.

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

The AT+CFUN test command returns the values of the supported parameters. The AT+CFUN read command returns the current functionality value.

The AT+CFUN write command can be used to reset the ME, to choose one of the SLEEP modes or to return to full functionality.
