Hi Aaron Thanks, I will give that a whorl and report back. I guess something like if the timestamp is older than say 10 minutes they should not be trusted (either not shown, or marked in some way). Chris Zitat von "Aaron McCarthy" : Hi, On Fri, 17 Jan 2014 17:09:37 christopher.l...@thurw

Hi Chris, you can get the timestamp in QML using: positionSource.position.timestamp But as said in my last mail, this will not help in this case, as the timestamp while waiting for a fix will be 'now'. also the valid-Properties are true while receiving the old position.I haven't found any way

Hi Juha and Marcel Thanks for your valuable hints. I should have said that I am using PositionSource from QMl. So unless I have missed something (always possible) I don't get the timestamp. The longitudeValid and lattitudeValid are the next things I will test. In the future it might be poss

Hi, I can see the same behaviour, too. The timestamp is not really helpfull, as this is the timestamp when you get the position, not when this position was seen. And while waiting for a fix you get an updated position every 30 seconds with a new, current timestamp. Another observation I made is

Chris, I see the same behaviour. But won't the timestamp method in QGeoPositionInfo help you? If the stamp differs a lot from current time, then it is likely to be invalid in your case. At least that is what I see in my application, the first update has the timestamp set to the time when GPS was l

Hi all Is it possible that the Jolla GPS / GPS Software stack initially shows the last location acquired? This is the behaviour I am observing. At the moment I am sitting in an office building, which has poor GPS reception, yet my app immediately shows GPS Coordinates. By peaking I can s
