How to get NMEA sentences out of GPS device?
how can I get the raw NMEA data out of a GPS device?
QGeoPositionInfo doesn't provide it...
You could subclass "QNmeaPositionInfoSource":http://doc.qt.io/qt-5/qnmeapositioninfosource.html and reimplement parsePosInfoFromNmeaData() to capture the raw NMEA sentence:
bool MySource::parsePosInfoFromNmeaData(const char * data, int size, QGeoPositionInfo * posInfo, bool * hasFix) override
// Store the raw sentence for later retrieval
this->sentence += QString(data, size);
// Call the base implementation to process the sentence return QNmeaPositionInfoSource::parsePosInfoFromNmeaData(data, size, posInfo, hasFix);
that sounds very interesting.
But as QNmeaPositionInfoSource requires a QIODevice now the goal was to find out what device file is emitting the GPS' data...
Sorry, I'm absolutely rookie to android development.
Hmm... reading through the documentation again, I might have misunderstood how QNmeaPositionInfoSource works.
I have to admit I don't have experience with the Qt Positiioning classes; try asking at the "Interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest where you can find Qt engineers (you'll need to subscribe first)
