3.2 AT+CIND Indicator control
The
AT+CIND
command controls the presentation of Indicator Event Reports related to various functions such
as battery charge level, signal quality, service availability, sound generation, indication of unread short mes-
sages, full SMS storage, call in progress or roaming activities.
Use of
AT+CIND
has become outdated. Rather we recommend the more powerful
AT^SIND
command which is
easier to use and provides additional indicators. All indicators provided by
AT+CIND
can be handled with
AT^SIND
as well.
AT+CIND
supports two ways to get the values related to indicators:
• One approach is to query the current status of each indicator by using the read command
AT+CIND
?. It
returns the status no matter whether the indicator has been registered with the write command
AT+CIND
=[ [, [,...]]].
• The other way is an event-driven notification based on the "
+CIEV
" URCs. In this case, the ME will automat-
ically send a message to the application, whenever the value of an indicator changes. The application should
be designed to react adequately when receiving a URC.
The presentation of these URCs depends on two settings:
- The indicators must be registered with the write command
AT+CIND
=[ [, [,...]]]. When the
ME is switched on all of them are in registered mode. Any indicator can be excluded if deregistered with
=0. To register or deregister an indicator the
AT+CIND
write command requires to type the value
=1 or 0 exactly at the position where the indicator is located in the list. This is not necessary with
AT^SIND
which allows to specify indicators by name. See examples below.
- The presentation of the registered indicators must be enabled with
AT+CMER
.
