Extended signal quality +CESQ

The +CESQ command returns received signal quality parameters. This command issues a valid response only when the modem is activated. v2.0.x

For reference, see 3GPP 27.007 Ch. 8.69.

Note: When Narrowband Internet of Things (NB-IoT) system mode is used and the device is in RRC CONNECTED state, old signal quality parameter values are reported. The values are recorded and reported from the previous RRC IDLE state.
