[explicit] NmeaLocationDataSource::NmeaLocationDataSource(QObject *parent = nullptr)
Creates an NMEA data source object.
Locations created from an NMEA data source object instantiated with this constructor will have a SpatialReference of WGS84.
[explicit] NmeaLocationDataSource::NmeaLocationDataSource(const Esri::ArcGISRuntime::SpatialReference &receiverSpatialReference, QObject *parent = nullptr)
Creates an NMEA data source object.
Locations created from an NMEA data source object instantiated with this constructor will have a SpatialReference defined by the receiverSpatialReference parameter. This constructor can be used when a receiver is outputting locations in a SpatialReference other than WGS84, such as when using a reference base station.
NmeaLocationDataSource::NmeaLocationDataSource(const Esri::ArcGISRuntime::SpatialReference &receiverSpatialReference, const Esri::ArcGISRuntime::SpatialReference &outputSpatialReference, QObject *parent = nullptr)Creates an NMEA data source object.
Locations created from an NMEA data source object instantiated with this constructor will be projected from the SpatialReference defined by the receiverSpatialReference parameter to the SpatialReference defined by the outputSpatialReference parameter. If the outputSpatialReference parameter is empty, the locations will not be projected and the locations will be in the receiverSpatialReference. This constructor can be used when a receiver is outputting locations in a SpatialReference other than WGS84, such as when using a reference base station, and/or the application requires the output locations to be projected to a different SpatialReference.
NmeaLocationDataSource::NmeaLocationDataSource(const Esri::ArcGISRuntime::SpatialReference &receiverSpatialReference, const Esri::ArcGISRuntime::SpatialReference &outputSpatialReference, Esri::ArcGISRuntime::DatumTransformation *outputDatumTransformation, QObject *parent = nullptr)Creates an NMEA data source object.
Locations created from an NMEA data source object instantiated with this constructor will be projected from the SpatialReference defined by the receiverSpatialReference parameter to the SpatialReference defined by the outputSpatialReference parameter using the outputDatumTransformation. If the outputSpatialReference parameter is nullptr , the locations will not be projected and the locations will be in the receiverSpatialReference; if the outputDatumTransformation parameter is set it will be ignored. This constructor can be used when a receiver is outputting locations in a SpatialReference other than WGS84, such as when using a reference base station, and/or the application requires the output locations to be projected to a different SpatialReference using a DatumTransformation.
[override virtual noexcept] NmeaLocationDataSource::~NmeaLocationDataSource()
Destructor.
[override virtual protected slot] void NmeaLocationDataSource::onStart()
Reimplements: AbstractLocationDataSource::onStart().
Reacts to start requests by starting the location data source.
Note: You should not call this method directly - use start instead.
[override virtual protected slot] void NmeaLocationDataSource::onStop()
Reimplements: AbstractLocationDataSource::onStop().
Reacts to stop requests by stopping the location data source.
Note: You should not call this method directly - use stop instead.
Esri::ArcGISRuntime::DatumTransformation *NmeaLocationDataSource::outputDatumTransformation() constReturns the DatumTransformation to be used in the project operation.
If set, this property will be used as the DatumTransformation in the call to GeometryEngine::project(const Esri::ArcGISRuntime::Geometry&, const Esri::ArcGISRuntime::SpatialReference&, Esri::ArcGISRuntime::DatumTransformation*). For this property to be used the outputSpatialReference also has to be set.
Esri::ArcGISRuntime::SpatialReference NmeaLocationDataSource::outputSpatialReference() constReturns if set calls the GeometryEngine::project(const Esri::ArcGISRuntime::Geometry&, const Esri::ArcGISRuntime::SpatialReference&) method to generate the output spatial reference.
The projected point will be stored in NmeaLocation::position. If this property is empty , the NmeaLocation::position will be contain the original incoming x,y,z values from the NMEA data sentence and the receiverSpatialReference.
void NmeaLocationDataSource::pushData(const QByteArray &data)Reads the input NMEA data, with which it creates a NmeaLocation.
When pushing data
Example: $GPGGA, 092750.000, 5321.6802,N, 00630.3372,W, 1, 8, 1.03, 61.7,M, 55.2,M,,*76 $GPGSA,A, 3, 10, 07, 05, 02, 29, 04, 08, 13,,,,, 1.72, 1.03,1.38*0A $GPGSV, 3, 1, 11, 10, 63, 137, 17, 07, 61, 098, 15, 05, 59, 290, 20, 08, 54, 157,30*70 see https://www.nmea.org/ for more information on the NMEA standard. The QByteArray can be obtained by, for example, converting from a QString; or by connecting to a GPS device, (either via QBluetoothSocket or QSerialPort) using QIODevice::read(qint64 maxSize).
Returns the SpatialReference to be assigned to the output NmeaLocation, the default is WGS84
By default this will be WGS84 for its horizontal (WKID=4326) and vertical reference systems (WKID=115700), this can be set to a different SpatialReference if a receiver returns locations in a different reference system.
[signal] void NmeaLocationDataSource::satellitesChanged(const QList<Esri::ArcGISRuntime::NmeaSatelliteInfo> &satellites)
Signal emitted when the satellites change.
[signal] void NmeaLocationDataSource::sentenceReceived(const QString &sentence)
Signal emitted when a sentence is received.
