Ok, I understand, but I'm still wondering : - QtSensors and compas will provide the azimuth of the device, so acting it like a compas, for instance, top of the device is pointing to the north. - QGeoPosition is providing GPS info with latitude and longitude, and I was thinking that the direction attribute was in fact the first derivative of the position, which is different from the compas return value, for instance I'm moving west while pointing top of device to the north.
So how to get the first derivative of GPS position, deriving it by hand ? Like calling the azimuth method on the two last GPS fix ? Have a nice week, Damien. _______________________________________________ SailfishOS.org Devel mailing list
