Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish
Hi Aaron
Adding that information proved easier than I had expected: it just
took a few minutes during breakfast!
void SatInfoSource::onSatsInViewUpdated(const QListQGeoSatelliteInfo
list) {
int newInView = list.count();
if (newInView != _satsInView) {
qDebug() satInfoSource.cpp: onSatsinViewUpdated:
QString::number(newInView, 'g', 2);
for (int i = 0; i newInView; i++ ) {
qDebug() satsInView: id:
list[i].satelliteIdentifier() , system:
list[i].satelliteSystem() , strength: + list[i].signalStrength();
}
_satsInView = newInView;
emit satellitesInViewChanged(newInView);
}
}
The for loop is new, and gives the following output.
[D] SatInfoSource::onSatsInViewUpdated:59 - satInfoSource.cpp:

I will have to write some more code to spit out the sat ids to the
debug console. At the moment my SatInfoSource declarative plugin is
ultra-simple, it just exposes the numbers of Sats InView and InUse,
nothing more.
At the moment my hypothesis is based on the circumstantial evidence
that new newer devices (Jolla and Galaxy) show roughly double the
number of older GPS only devices (N9, Garmin).
Cheers

Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish
Hi all A slight correction to my previous post I think that the high number of Sats in View shown on the Jolla means that it is showing both GPS and Glonass Satellites, and thus gives a figure almost double of that I was used to from the Nokia N9 and classic GPS devices. Comparing various devices I get the following readings: Sats in use / Sats in View / Device / Technology 6 / 9 / Nokia N9 / GPS only 5 / 20 / Jolla / GPS and Glonass 15 / 21 / Samusung Galaxy Note 3 / GPS and Glonass 9 / Garmin GPSmap 60CSx / GPS only So the Sats in View figure of the Jolla is plausible.

I show 15 for the Galaxy above, but have seen readings of 18 and 19. Chris Zitat von christopher.l...@thurweb.ch: But SatsInView jumps straight to 17 and stays at 17.

Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish
Hi, just a small note if everyone else is waiting for this: QGeoSatelliteInfoSource is working since Sailfish 1.0.3.8 The only problem here is what the system (GPS/GLONASS) is not set, it is QGeoSatelliteInfo::Undefined.

Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish
Hi Marcel I can confirm that I am getting QGeoSatelliteInfoSource info too. SatsInUse is changing, before levelling out at 4, which is plausible as I am sitting inside. But SatsInView jumps straight to 17 and stays at 17. This figure seems less plausible to me. It maybe down to a bug in my code, but if so I have yet to find it. (Tomorrow I will test outside, to see if that makes a difference). mfg Chris Zitat von Marcel mar...@aliquis.de: Hi, just a small note if everyone else is waiting for this: QGeoSatelliteInfoSource is working since Sailfish 1.0.3.8 The only problem here is what the system (GPS/GLONASS) is not set, it is QGeoSatelliteInfo::Undefined.

Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish
Hi Chris, Thanks for the quick response on a sunday... I've already seen that there is no GPS in the Emulator, but since Friday I have my own Jolla device :) As first project I'm trying to create a simple app showing the GPS infos similiar to GPS Info Qt on Symbian. QML PositionSource (and in C++ QGeoPositionInfoSource) is working without problems on my real device (besides the accuracies are the same as stated in my first mail), so I can access the hardware, but there seems to be something missing for the SatelliteInfoSource. Greetings, Marcel Am Sonntag, 12. Januar 2014 schrieb christopher.l...@thurweb.ch: Hoi Marcel Good to see a fellow Sailfish GPS hacker at work. I am fighting with PositionSource (in QML), but have not got as far as SatelliteInfoSource on a real device - but I hope to soon, as the app I am porting has a C++ plugin to expose SatelliteInfoSource to QML. You don't state what target you are using. If your target is the Emulator, then I don't think you will be able to get SatelliteInfoSource working. Evidently the Emulator has no real GPS hardware, and as far as I know there is not (yet) a working simulator plugin that would provide SatelliteInfoSource. You should find a thread on this topic in this mailing-list from around Christmas time.
