Write command
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). The alarm call
AT+CALA=<time>
can adopt two functions, depending on whether or not you switch the GSM
[,<n>[,<type>[,<te
engine off after setting the alarm:
xt>]]]
Reminder call: You can use the alarm function as a wake-up or reminder call.
Alarm mode:
Response
OK
If setting fails:
+CME ERROR: <err> Refer Chapter 7.1.1, pg. 181, for <err> values.
TC3X_ATC_01_V04.00
For this purpose, set the alarm as described below and do not
switch off or power down the ME. When executed the call
comes as an Unsolicited Result Code.
Applies to TC35, TC37 and TC35 Terminal.
You can use the alarm call to restart the ME when powered
down. For this purpose, set the alarm as described below. Then
power down the ME by entering the AT^SMSO command (pg.
159). 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
operation. 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 ZIF interface)
to ground. If your application is battery powered note that
charging cannot be started while ME is in Alarm mode. For
details please refer to the "Hardware Interface Description"
supplied with your GSM engine.
Applies to TC35 / TC37 modules. TC35 Terminal does not
support the Alarm mode.
