Unsolicited Result Codes
URC 1
+CALA: [<text>]
Indicates reminder message.
URC 2
^SYSSTART ALARM MODE
+CALA: <text>
Indicates ME wake-up into Alarm mode.
URC 3
+CALA: Unexpected Error
Indicates Unexpected CALA functionality error. When such an error occurs all alarm timers will be stopped
and reset to default values.
Parameter Description
Format is "yy/MM/dd,hh:mm:ss". For example, 6th of July 2005, 22:10:00 equals to "05/07/06,22:10:00". See
also AT+CCLK.
If you attempt to set <time> to a date and time which is older than the ME's current time, one "+CALA" URC will
be returned, and no alarm timer will be set.
To clear a given alarm before its scheduled time simply enter an empty string for parameter <time>.
Integer type value indicating the array index of the alarm.
0 .. 4
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 ME is totally disconnected from power supply the most recently saved configuration of +CALA: <time>,<n>
[,<type>[,<text>]] will be presented when ME is powered up.
• When an alarm is set on a given ASC interface only this interface will be allowed for further AT+CALA read/
write operations. Using the read/write AT+CALA command on another interface will result an ERROR until the
last alarm timer was executed or deleted.
