ported <tlength>) OK

Read command
AT+CALA?
Read command returns the list of current active alarm settings in the ME.
Response
+CALA: <time>[,<n>[,<type>[,<text>]]]
If error is related to ME functionality:
+CME ERROR: <err>
Parameter
See write command
Write command
AT+CALA=<time>
[,<n>[,<type>
[,<text>]]]
The write command sets an alarm time in the ME. When the alarm is timed out
and executed the ME returns an Unsolicited Result Code (URC) and the alarm
time is reset to “00/01/01,00:00:00”.
The alarm can adopt two functions, depending on whether or not you switch the
GSM engine off after setting the alarm:
Reminder message:
You can use the alarm function to generate reminder mes-
sages. For this purpose, set the alarm as described below and
do not switch off or power down the ME. When executed the
message comes as an Unsolicited Result Code.
Alarm mode: Applies to TC35i module only. Alarm mode is not permitted for
use with TC35i Terminal. For details see [2].
You can use the alarm function to restart the ME when pow-
ered down. For this purpose, set the alarm as described below.
Then power down the ME by entering the AT^SMSO command
(pg. 208). When the alarm time is reached, the ME will wake up
to Alarm mode. To prevent the ME from unintentionally logging
into the GSM network, Alarm mode provides restricted opera-
tion. Upon wake-up, the ME indicates an Unsolicited Result
Code which reads: ^SYSSTART ALARM MODE. A limited
number of AT commands is available during Alarm mode:
AT+CCLK, AT+CALA, AT^SBC, AT^SCTM, AT^SMSO. The
ME remains deregistered from the GSM network.
If you want the ME to return to full operation (normal operating
mode) it is necessary to drive the ignition line (IGT pin of appli-
cation interface) to ground. If your application is battery pow-
ered note that charging cannot be started while the ME is in
Alarm mode. For details please refer to [1].
Response
OK
If setting fails:
+CME ERROR: <err> Refer to Chapter 8.1.1, pg. 251, for <err> values.
