19.2AT+CALA Set alarm time

The AT+CALA write command can be used to set an alarm time in the ME or to clear a programmed alarm. When the alarm time is reached and the alarm is 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 messages. 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 which reads "+CALA".

•Airplane mode: The alarm function can be used to wake up the ME at a scheduled time. For this purpose, set the alarm as described below. Then power down the ME by entering the AT^SMSO command. When the alarm time is reached the ME enters the Airplane mode, notified to the user by the URC "^SYSSTART AIRPLANE MODE" and, if available, by a user defined text message (specified with <text>). In Airplane mode, the RF interface of the ME is shut down to prevent it from unintentionally logging into the GSM network. All AT com- mands whose execution requires a radio connection are disabled. A list of AT commands supported during Airplane mode can be found in Section 21.4, Availability of AT Commands Depending on Oper- ating Mode of ME. To return from Airplane mode to Normal mode use the AT^SCFG command and set the parameter <map> to "off". This immediately activates the RF interface and restores access to all AT com- mands. The URC "^SYSSTART" notifies the user that the ME has returned to Normal mode. Please note that setting an alarm with AT+CALA is one method to wake up into Airplane mode. The second approach is using the AT^SCFG command, parameter <mapos>. For further detail on Airplane mode refer to Section 2.14,

AT^SCFG.

The AT+CALA test command returns the supported array index values <n>, the supported alarm types <type> and the maximum length of the text <tlength> to be output.

The AT+CALA read command returns the current alarm settings in the ME.
