· Alarm settings on different Multiplexer channels (see Chapter 4.28):
- On each channel an individual <text> message can be stored, but only
one time setting applies. This means an alarm <time> set on one of the
channels overwrites the time setting on all remaining channels. There-
fore, the total number of alarm events returned by the read command
AT+CALA? will always be <n>=0, no matter whether different text mes-
sages are stored.
- When the alarm is timed out and executed the ME sends the URC only
on the channel where the most recent alarm setting was made. The
alarm time will be reset to “00/01/01,00:00:00” on all channels.
Example 1:
You may want to configure a reminder message for May 31, 2003, at 9.30h, in-
cluding the message "Good Morning".
Write command:
AT+CALA="03/05/31,09:30:00",0,0,"Good Morning"
OK
Do not switch off the GSM engine. When the alarm is executed the ME returns
the following URC:
+CALA: Good Morning
Example 2:
To set a fresh alarm using the same message as in Example 1, simply enter
date and time. <n>, <type>, <text>, <tlength> can be omitted:
AT+CALA="03/05/31,08:50:00"
OK
When the alarm is executed the URC comes with the same message:
+CALA: Good Morning
Examples
Example 3:
To configure the alarm mode, e.g. for May 20, 2003, at 8.30h, enter
AT+CALA="03/05/20,08:30:00"
OK
Next, power down the ME:
AT^SMSO
^SMSO: MS OFF
When the alarm is executed the ME wakes up to Alarm mode and displays a
URC. If available, this line is followed by the individual <text> most recently
saved. If no individual message was saved only the first line appears.
^SYSSTART ALARM MODE
+CALA: Good Morning
