At+Cind Indicator Control - Siemens MC35 Command Set

AT Command Set

4.19 AT+CIND Indicator control

MC35 supports indicator event reporting for the following items: battery capacity, signal quality, ser-
vice availability, generation of sound in the ME, indication of unread short messages, full SMS stor-
age, call in progress and roaming activities.
There are two ways to display the status and event reports by indicators:
1. You can directly query the current status of each indicator, simply by using the Read command
AT+CIND. The Read command returns the status no matter whether the indicator has been reg-
istered with the Write command AT+CIND=[<stat>[,<stat>[,...]]].
2. You can take advantage of Unsolicited Result Codes. These are 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:
a) The indicators must be registered with the Write command AT+CIND=[<stat>[,<stat>[,...]]].
By default, all of them are registered. Any URCs you do not need can easily be excluded if
deregistered with <stat>=0.
b) The URC presentation mode must be enabled with AT+CMER (see Chapter 4.26).

In the list above, all parameters are presented by the sequence used in the Test,
Read and Write commands.
MC35_ATC_01_V05.00
values and their <ind> ranges.
"battchg" Battery charge level (0-5),
where (0-5) means 0, 20, 40, 60, 80 or 100 per
cent of the the remaining battery capacity. If no
battery is connected to the ME, then the value will
be always equal to 5. See also Chapter 8.5.
"signal" Signal quality (0-7 or 99 if not measurable). The
indicated value is the bit error rate of the signal
received. See also Chapter 4.46.
"service" Service availability (0-1).
"sounder" Sounder activity (0-1). The indicator provides in-
formation about tones generated in the ME. The
value 1 means for example:
Incoming call - ME is ringing.
Waiting call – ME generates waiting call tone (if
call waiting is enabled).
Outgoing call – ME generates Call Progress tone.
Outgoing call – ME generates BUSY tone.
The value changes to 0, when the tone stops.
"message" Unread short message(s) (0-1).
"call" Call in progress (0-1). Voice und data calls only.
The indicator changes its value as soon as a call
has been established, for example when both in-
terlocutors are connected or when the call ends.
"roam" Roaming indicator (0-1).
"smsfull" A short message memory storage in the MT has
become full (1) or memory locations are available
(0); i.e. the range is (0-1).
integer type value, in the range stated above for the corresponding
