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 90 seconds
timer expires. If the device is in "alarm mode" and it does not receive the
#WAKE
command within 90s then it shuts down.
5 - the MODULE will make both the actions as for type=2 and
<type>=3
.
6 - the MODULE will make both the actions as for type=2 and
<type>=4
.
7 - the MODULE will make both the actions as for type=3 and
<type>=4
.
8 - 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 sets
High
the
RI
output pin. The
RI
output pin remains
High
until next
#WAKE
issue or
until a 90s timer expires. If the device is in "alarm mode" and it does not receive
the
#WAKE
command within 90s. After that it shuts down.
<text>
- unsolicited alarm code text string. It has meaning only if
<type>
is equal
to 2 or 5 or 6.
<recurr>
- string type value indicating day of week for the alarm in one of the
following formats:
“<1..7>[,<1..7>[, … ]]” - it sets a recurrent alarm for one or more days in the
week; the digits 1 to 7 corresponds to the days in the week (Monday is 1).
“0” - it sets a recurrent alarm for all days in the week.
<silent>
- integer type indicating if the alarm is silent or not.
0 - the alarm will not be silent;
1 - the alarm will be silent.
Note: a special form of the Set command, +CALA=””, deletes an alarm in the ME
Note: The "alarm mode" is indicated by hardware pin
CTS
to the
ON
status and
DSR
to the
OFF
status, while the "power saving" status is indicated by a
CTS
-
OFF
,
DSR
-
OFF
and
USB_VBUS
–
OFF
status. The normal operating status is
indicated by
DSR
–
ON or USB_VBUS – ON status
.
During the "alarm mode" the device will not make any network scan and will not
register to any network and therefore is not able to dial or receive any call or SMS,
the only commands that can be issued to the MODULE in this state are the #WAKE
and #SHDN, every other command must not be issued during this state.
AT+CALA?
Read command returns the list of current active alarm settings in the ME, in the
format:
[+CALA: <time>,<n>,<type>,[<text>],<recurr>,<silent>]
AT+CALA=?
Test command returns the list of supported index values (currently just 0), alarm
types, maximum length of the text to be displayed, maximum length of
<recurr>
and supported
<silent>
s, in the format:
+CALA: (list of supported <n>s),(list of supported <type>s),<tlength>,
<rlength>,(list of supported <silent>s)
Example AT+CALA="02/09/07,23:30:00+00"
