32 6. Function Description
When entering the service center number and the telephone number you have to place
them in “”.
The service center number must be written in international format, i.e. for a German
provider with a leading „+49“.
After entering the target number (finalize with <CR> ), the prompt for the SMS text >
appears. The text entry has to be completed with <CTRL Z> (not with <CR>!).
Save the settings so far with
AT&W
Now, the actual alarm function is configured:
AT^SCFG=“AutoExec“,1,0,0,0,”AT+CMSS=1”
When activating the DTR control line from the application, the SMS at the storage
location 1 (AT+CMSS=1) is sent to the stored target (0170123456789).
This is indicated at the serial interface:
^SCFG: "AutoExec",1,0,0,0,"AT+CMSS=1"
OK
+CMSS: 23
The message “+CMSS: 23“ returns the number of SMS messages already sent with this
SIM card.
In this case already existing data connections are ignored, i.e. sending SMS messages
would fail in this situation.
If you want to wait until an already existing data connection ends, you have to enter
AT^SCFG=“AutoExec“,1,0,0,1,“ AT+CMSS=1”
If you want to terminate an existing data connection for the case of an alarm, the
following must be entered
AT^SCFG=“AutoExec“,1,0,00.2,“ AT+CMSS=1”
.
The setting can be deactivated by entering the following:
AT^SCFG=“AutoExec“,0,0,0
The settings of this command are only stored with the command AT^SMSO.
