Confidential / Released
Integer type value indicating the type of the alarm.
0 Alarm indication: text message via serial interface
String type value indicating the text to be displayed when alarm time is reached; maximum length is
<tlength>.
By factory default,
<text> is undefined.
Note:
<text> will be stored to the non-volatile flash memory when the device enters the Power Down mode via
AT^SMSO. Once saved, it will be available upon next power-up, until you overwrite it by typing another text. This
eliminates the need to enter the full string when setting a fresh alarm.
<text> should not contain characters which are coded differently in ASCII and GSM (e.g. umlauts), see also
"Supported character sets" and "GSM alphabet tables".
Integer type value indicating the maximum length of <text>. The maximum length is 16.
Notes
• After the alarm was executed the parameter <time> of AT+CALA will be reset to "00/01/01,00:00:00", but
<text> will be preserved as described above.
• If TC35i is totally disconnected from power supply the most recently saved configuration of +CALA:
<time>[,<n>[,<type>[,<text>]]] will be presented when TC35i is powered up.
• Each time TC35i is restarted it takes 2s to re-initialize the RTC and to update the current time. Therefore, it
is recommended to wait 2s before using the commands
AT+CCLK and AT+CALA (for example 2s after
^SYSSTART has been output).
• Alarm settings on different Multiplexer channels (see
AT+CMUX):
- On each interface an individual
<text> message can be stored, but only one time setting applies. This
means an alarm
<time> set on one of the interfaces overwrites the time setting on all remaining inter-
faces. Therefore, the total number of alarm events returned by the read command
AT+CALA? will always
be
<n>=0, no matter whether different text messages are stored.
- When the alarm is timed out and executed, the ME sends the URC only on the interface where the most
recent alarm setting was made. The alarm time will be reset to "00/01/01,00:00:00" on all interfaces.
Examples
EXAMPLE 1
You may want to configure a reminder call for May 31, 2004, at 9.30h, including the message "Good Morning".
Do not switch off the GSM engine. When the alarm is executed the ME returns the following URC:
<type>
(num)
<text>
(str)
<tlength>
(num)
AT+CALA="04/05/31,09:30:00",0,0,"Good Morning"
OK
+CALA: Good Morning
