SELINT 2
AT+CSQ Execution command reports received signal quality indicators in the form:
+CSQ: ,
where
- received signal strength indication
0 - (-113) dBm or less
1 - (-111) dBm
2..30 - (-109)dBm..(-53)dBm / 2 dBm per step
31 - (-51)dBm or greater
99 - not known or not detectable
- bit error rate (in percent)
0 - less than 0.2%
1 - 0.2% to 0.4%
2 - 0.4% to 0.8%
3 - 0.8% to 1.6%
4 - 1.6% to 3.2%
5 - 3.2% to 6.4%
6 - 6.4% to 12.8%
7 - more than 12.8%
99 - not known or not detectable
Note: this command should be used instead of the %Q and %L commands,
since GSM relevant parameters are the radio link ones and no line is
present, hence %Q and %L have no meaning.
AT+CSQ=? Test command returns the supported range of values of the parameters
and .
Note: although +CSQ is an execution command without parameters, ETSI
07.07 requires the Test command to be defined.

3.5.4.4.5 Indicator Control - +CIND
+CIND - Indicator Control SELINT 2
AT+CIND=
[
[,[,…]]] Set command is used to control the registration state of ME indicators, in
order to automatically send the +CIEV URC, whenever the value of the
associated indicator changes. The supported indicators () and their
order appear from test command AT+CIND=?
Parameter:
- registration state
0 - the indicator is deregistered; there’s no unsolicited result code (+CIEV
