3.7.2 Alarm function

Once the current time has been set, the alarm function can be setup.

3.7.2.1 Regulate the Alarm time & behavior

• Send command

AT+CALA="<time>",0,<type>,"<text>"<cr>

where:

<time> is the Alarm time string in the same format of the clock setting command:

yy/MM/dd,hh:mm:ss±zz

where:

yy : two digits year (00-99)

MM : two digits month (01-12)

dd : two digits day (01-31)

hh : two digits hour (00-24)

mm : two digits minute (00-60)

ss : two digits seconds (00-60)

±zz: signed two digits timezone (-11 - +11)

<type> is the Alarm behavior:

0 - reserved for other equipment use.

1 - the MODULE simply wakes up fully operative as if the ON/OFF button had been pressed. If the

device is already ON at the alarm time, then it does nothing.

2 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully

operative. In both cases the MODULE issues an unsolicited code every 3s:

+ALARM: <text>

where <text> is the +CALA optional 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 MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully

operative. In both cases the MODULE 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.

4 - the MODULE wakes up in "alarm mode" if at the alarm time it was off, otherwise it remains fully

operative. In both cases the MODULE brings the pin GPIO6 high, provided its <direction> has

been set to alarm output, and keeps it in this state 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.
