2.9 AT^SMSO Switch Off EHS6
AT^SMSO initiates EHS6's power-off procedure. Do not send any other AT command after this.
Low level of the ME's V180 signal and the URC "^SHUTDOWN" notify that the procedure has completed and the
ME has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until the
V180 signal has gone low and until the URC "^SHUTDOWN" is displayed. Otherwise, you run the risk of losing
data. For further details on how to turn off the ME refer to [2]. If a fast switch off (see parameter <fso> in
AT^SCFG) is enabled, there is no reply like OK, ERROR or any "^SHUTDOWN" URC.
Syntax
Unsolicited Result Code
^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off in less than 1 second.
If <fso> is used to enable a fast ME switch off, there will be no "^SHUTDOWN" URC.
Note
• If <fso> is used to enable a fast ME switch off, flash access cycles (writing/deleting) will be finalized, but there
will no longer be any network deregistration, the current settings will not be saved and there will be no further
output on the interfaces. All other jobs will be deleted and logical data consistance cannot be guaranteed.
