+CALA – Alarm Management
Execute command
Read command
AT+CALA?
Reports the current alarm time stored in the internal Real Time Clock,
if present, in the format:
+CALA: <time>,<n>,<type>[,<text>]
Write command
AT+CALA = [<time>
[,<n>[,<type>[,<text>]]]]
Stores in the internal Real Time Clock the current alarm time and
settings defined by the parameters <time>, <n>,<type>,<text>.
When the RTC time reaches the alarm time then the alarm starts, the
behaviour of the GM862-GPRS depends upon the setting <type> and if
the device was already ON at the moment when the alarm time had
come.
Parameter:
<time> - current alarm time in the format : "yy/MM/dd,hh:mm:ss±zz"
as defined for +CCLK command.
<type> - alarm behaviour type
0 - reserved for other equipment use.
1 - the GM862-GPRS simply wakes up fully operative as if the
ON/OFF pin had been pressed. If the device is already ON at the
alarm time, then it does nothing.
2 - the GM862-GPRS wakes up in "alarm mode" if at the alarm time
it was off, otherwise it remains fully operative. In both cases the
GM862-GPRS issues an unsolicited code every 3s:
+ALARM: <text>
Where <text> is the other +CALA parameter previously set.
The device keeps on sending the unsolicited code every 3s until a
#WAKE or #SHDN command is received or a 90s timeout
occurs. If the device is in "alarm mode" and it does not receive
the #WAKE command within 90s then it shuts down. (default)
3 - the GM862-GPRS wakes up in "alarm mode" if at the alarm time
it was off, otherwise it remains fully operative. In both cases the
GM862-GPRS starts playing the alarm tone on the selected path
for the ringer (see command #SRP)
The device keeps on playing the alarm tone until a #WAKE or
#SHDN command is received or a 90s timeout occurs. If the
device is in "alarm mode" and it does not receive the #WAKE
command within 90s then it shuts down.
