3.1. Turn on/off the GNSS

Default parameters are used in this example to turn on GNSS. After turning on GNSS, NMEA sentences
will be outputted from "usbnmea" port by default; and GNSS can be turned off via AT+QGPSEND.
AT+QGPS=1
OK
//After turning on GNSS, NMEA sentences will be outputted from "usbnmea" port by default.

OK
3.2. Application of GNSS <nmeasrc>
When GNSS is turned on and <nmeasrc> is set to 1, NMEA sentences can be acquired directly via
AT+QGPSGNMEA.
AT+QGPSCFG="nmeasrc",1
OK
AT+QGPSGNMEA="GGA"

LTE_Standard_GNSS_Application_Note
//Turn on GNSS.
//Obtain positioning information.
//Turn off GNSS.
//Set <nmeasrc> to 1 to enable acquisition of NMEA
sentences via AT+QGPSGNMEA.
//Obtain GGA sentence.
//Set <nmeasrc> to 0 to disable acquisition of NMEA
sentences via AT+QGPSGNMEA.
//Acquisition of NMEA sentences via AT+QGPSGNMEA
was disabled, and thus GGA sentences cannot be obtained.
