^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off in less than 1 second.
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] .
