Unsolicited Result Code
^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off within 1 second
Command Description
The exec command initiates the power-off procedure. Low level of the module's VDD pin and display of URC
"
^SHUTDOWN" verifies that the procedure has completed and the module has entered the POWER DOWN mode.
Therefore, be sure not to disconnect the operating voltage until VDD is low or until URC "
^SHUTDOWN" is dis-
played . 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 command after this command.
• 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.
