2.10AT^SMSO Switch off mobile station

AT^SMSO initiates the power-off procedure. High level of the module's PWR_IND pin and the URC "^SHUTDOWN" notify that the procedure has completed and the module has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until PWR_IND is high or until the URC "^SHUTDOWN" is displayed. Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2].

Notes

•Do not send any other AT command after AT^SMSO.

•If AT^SMSO is entered on one of the Multiplexer channels the ME closes the Multiplexer channels, terminates the Multiplexer and deactivates all other functions. Then, the URC "^SHUTDOWN" will be issued on the phys- ical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with the Multiplex driver.

•If both interfaces ASC0 and ASC1 are connected the URC appears on both of them.

•If the module is in NORMAL mode and the charger is connected to the VCHARGE line, the AT^SMSO com- mand causes the module to shut down shortly and then start into the CHARGE ONLY mode. If the module is in CHARGE ONLY mode the AT^SMSO command is not supported at all. In both cases, the module can only be switched off by disconnecting the charger. See also [2].
