Are you certain that the two non-working devices have a valid position fix? It is quite possible for a fix to take up to 2 mins and if GPS only is permitted and you are inside a building... Another test might be to check whether other apps (e.g. the maps app) can retrieve the position .
If you are certain that the above points are not the issue then I think it is time to put this into a bug report on https://bugreports.qt.io. The report should contain all the info already provided. In addition there should be information like any output you see on the command line. I am fairly certain it should mention something about provider. When you press "Locate & Update", what does the display say? What is mentioned in the UI as source? LBNL I'd like you to apply https://codereview.qt-project.org/#/c/124254/ before you run the example. This adds a bit more details on the output and improves error handling. -- Alex ________________________________ From: interest-bounces+alexander.blasche=theqtcompany....@qt-project.org <interest-bounces+alexander.blasche=theqtcompany....@qt-project.org> on behalf of Federico Buti <bacaro...@gmail.com> Sent: Wednesday, August 26, 2015 09:37 To: Jason H Cc: interest@qt-project.org Subject: Re: [Interest] Qt positioning Hi all. Sorry for the delay in answering my own thread. Being busy doing other stuff I had no time to further test my issue. As suggested by Alex I've started studying the problem with the built-in examples. I've deployed the "Geoglickr" to my three devices. In accordance to the results I've obtained with my initial toy example the application correctly fetched coordinates on just one device out of three. More in details: - Lenovo A806 [rooted with AOSP 4.4.2] nan values, hitting "Locate & update" does not change a thing - Archos 50 Titanium [stock Android 4.2.2] Correct value dispayed at startup - Galaxy Tab2 (GT-P7500) [stock Android 4.0.4] nan values, hitting "Locate & update" does not change a thing Is there some trace/output I can attach or some other specific test I can execute? Should I add other relevant info (e.g. kernel version, build number)? Thanks in advance, F. On 19 August 2015 at 22:24, Jason H <jh...@gmx.com<mailto:jh...@gmx.com>> wrote: Nope, did not know.
