3.2 AT+CIND Indicator control
This command controls information about status changes via URC presentation of the MC55 or connected items,
e.g. 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Use of this command is outdated since additional indications and functionality are available with
AT^SIND
.
AT+CIND
supports two ways to get the values related to indicators:
• 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
=[
<state>
[,
<state>
[,...]]].
• Evaluate one of the "
+CIEV
" URCs which the ME automatically sends to the application, whenever the value
of the associated indicator changes.
The presentation of these URCs depends on two settings:
- The indicators must be registered with the write command
AT+CIND
=[
<state>
[,
<state>
[,...]]]. By
default, all of them are registered when the ME is switched on. Any URC can be excluded if deregistered
with
<state>
=0.
- URC presentation must be enabled with
AT+CMER
.
