Parameter
<time> string type value; format is "yy/MM/dd,hh:mm:ss", where characters
indicate year (two last digits), month, day, hour, minutes. E.g. 6
th
of
May 2003, 22:10:00 hours equals to “03/05/06,22:10:00" (see also
AT+CCLK in Chapter 4.7). Note: if <time> equals current date and
time or is set to an earlier date, TA returns +CME ERROR: <21>.
<n> Integer type value indicating the array index of the alarm.
The ME allows to set only one alarm at a time. Therefore, the list of
supported alarm events indicated by the test command AT+CALA=?
is <n>=0. If a second alarm time is set, the previous alarm will be de-
leted. Therefore, the read command AT+CALA will always return
<n>=0. This is also true if individual settings are made on the various
Multiplexer channels, for details see notes below.
<type> Integer type value indicating the type of the alarm
0 Alarm indication: text message via serial interface
<text> 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 (pg. 208). 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.
For text coding see Chapters 1.5 and 8.5.
<tlength> integer type value indicating the maximum length of <text>. The
maximum length is 16.
Unsolicited result code
Indicates reminder message:
+CALA: <text>
Indicates ME wake-up into Alarm mode:
^SYSSTART ALARM MODE
+CALA: <text>
If autobauding is active (AT+IPR=0) the URCs ^SYSSTART ALARM MODE
and +CALA: <text> do not appear. Therefore, avoid using Alarm mode in con-
junction with autobauding.

Note
· After the alarm was executed the parameter <time> of AT+CALA will be re-
set to "00/01/01,00:00:00", but <text> will be preserved as described above.
· If the ME is totally disconnected from power supply the most recently saved
configuration of +CALA: <time>[,<n>[,<type>[,<text>]]] will be retained
when the ME is powered up.Yet take into account that the RTC will be reset
to its default <time> = “02/01/01,00:00:00” (see Chapter 4.7).
· Each time TC35i is restarted it takes 1s to re-initialize the RTC and to up-
date the current time. Therefore, it is recommended to wait 1s before using
the commands AT+CCLK and AT+CALA (for example 1s after ^SYSSTART
has been output).
