2.2.6. AT+QGPSGNMEA Acquire NMEA Sentences
The command acquires NMEA sentences. Before using this command, GNSS must be turned on via
AT+QGPS
, and set
<NMEA
_
src>
into 1
to enable acquisition of NMEA sentences via
AT+QGPSGNMEA
.
The sentence output can be disabled via
AT+QGPSCFG="gpsnmeatype",0
,
AT+QGPSCFG="glon
assnmeatype",0
,
AT+QGPSCFG="galileonmeatype",0
and
AT+QGPSCFG="beidounmeatype",0
.
If sentence output is disabled,
AT+QGPSGNMEA
can still be used to acquire NMEA sentences on
condition that the GNSS has already acquired sentences via this command after its activation. And the
sentences acquired via the command will be the last ones that have ever been acquired.
