String values and their <indValue> ranges.
More indications are available via AT^SIND. Therefore use of AT^SIND for control of all indications is recom-
mended.
The following indications are accessible via AT+CIND:
"battchg" Battery charge level 0..4 or 5 if no measuring is performed, e.g because no bat-
tery is connected. Also refer to AT^SBC.
"signal" Signal quality (0..7) or (99) if not measurable
The indicated value is the bit error rate of the signal received. Bit errors are esti-
mated values. See also AT+CSQ.
"service" Service availability (0-1)
0: Not registered to any network
1: Registered to home network or, if "roam"=1 then registered to another net-
work
"sounder" Sounder activity (0-1)
Reports every event that causes the ME to generate a tone.
Value 1 means for example:
Incoming call - ME is ringing. Note that the URC "+CIEV: sounder" will be out-
put only if ringing tones are activated with AT^SRTC.
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 at memory location <mem1> (0-1); refer to AT+CPMS
"call" Call in progress (0-1). Indicator value is "1" if at least one call is in state "active"
or "held".
Depending on the parameter <succ> selected with AT^SCFG the indicator
"call" will be issued
• when a state transition ends in state "active" or state "unknown", if
<succ>="restricted",
• when any state transition (including transitions beginning or ending in state
"unknown") occurs in the list of active calls or when a traffic channel is
established, if <succ>="verbose".
Also refer to Section 7.1, Call Status Information.
"roam" Roaming indicator (0-1)
0: Registered to home network or not registered
1: Registered to other network
"smsfull" A short message memory storage in the MT has become full (1) or memory
locations are available (0), i.e. range is (0-1)
"rssi" Received signal (field) strength (0..5) or (99) if not measurable
0: signal strength <= -112 dbm
1-4: signal strength in 15 dbm steps
5: signal strength >= -51 dbm
Received signal (field) strength can also be obtained with AT+CSQ. However,
the signal strength is scaled to value range 0..31 by this command.
0 Indicator is deregistered. The indicator will not be presented as "+CIEV" URC,
but can be queried with AT+CIND?.
