[Bug 1468020] Re: Two GPS compatible apps conflict and loose GPS
Position does not only freeze as I described in previous message, but if there is other GPS apps running, then uNav app, for example, does not only looses position, but it works very strangely, it is very choppy, and does not know the direction (map swings in many directions constantly), and finally freezes untill the the apps are switched again. But If no other gps apps are running, all working very well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1468020 Title: Two GPS compatible apps conflict and loose GPS To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1468020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm I experience exactly the same problem as described in #6 comment, and filled a duplicate bug lately #1573140. But I cannot confirm information in other comments #1, #2, because GPS always starts working again if I switch apps, but GPS stops again after a minute and apps have to be switched again and so on.

[Bug 1468020] Re: Two GPS compatible apps conflict and loose GPS
@thomas-voss As I can see I didn't explain it well. With I mean that when you are travelling in that 'dark zone' the GPS doesn't receive positions. If that 'dark zone' is short, when you exit the phone finds the satellites position easily; but if that zone is long when you exit it tries to connect to AGPS to determine the satellites positions and is then when it fails. I.e. if you cross a short tunnel the phone doesn't need AGPS when exit but if you cross a long one it needs it and the location services fails. There are only my thoughts after analyse what I have observed. It happens either if you have wifi enabled or only phone network. Apart of that: - I haven't tried if the phone gets positions with only GPS. I tried it one year ago and it didn't work but I haven't tried it again. - I tried today to put the phone in plain mode, clear .cache, reboot and open SensorsStatus. It has received positions in about 2 minutes (without wifi nor phone network, i.e. without AGPS). - I'll try to travel in plane mode (with 2 GPS apps opened) when I have a chance. I hope this to be useful. :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1468020 Title: Two GPS compatible apps conflict and loose GPS To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1468020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 1468020] Re: Two GPS compatible apps conflict and loose GPS
Let's clarify on the terminology here first: AGPS refers to assistance technology that enables a GPS chipset to query relevant information (ephemeris/almanac) over a data link (mobile data/wifi) that offers more bandwidth than the satellite down link (~1Hz). With that, *if* you are travelling in situations with little satellite visibility, AGPS will be of no help, as the GPS chipset just has no beacons from satellites to determine which ones are visible and subsequently triangulate a position. I think you are referring to the network-based positioning which estimates positions based on visible wifis and the radio cell the phone is currently connected to. For the scenario you are mentioning: What kind of "dark zones" did you drive through? Did you have wifi enabled?

Try running uNav for a bit, switch to the camera and take some photos, and a quick video. Return to uNav, and see if uNav updates your GPS position.

[Bug 1468020] Re: Two GPS compatible apps conflict and loose GPS
In my bq Aquaris E4.5 Ubuntu Edition with Ubuntu 15.04 (r296) I have done these tests: A. uNav running alone: - A few times it has arrived to a state of not receiving new positions. I think this is due to not having access to AGPS because the network is down or the phone has not access to a network. B. uNav and SensorsStatus running at the same time: - With uNav on the foreground and SensorsStatus on the background, after a while uNav arrives to a state of not receiving new positions. - Changing to SensorsStatus it initially doesn't show any position and immediately it receives new positions. - Changing to uNav it starts again to receive new positions and after a while it stops receiving new positions. - If you change again to SensorsStatus and after that to uNav, it starts again to receive new positions. - If you kill SensorsStatus uNav receives new positions and it works well. C. uNav and HERE Maps running at the same time: - You can reproduce the same described in B with these two apps. D. uNav and Google maps (in the browser) running at the same time: - If you permit to Google maps to access to your location you can reproduce the same described in B with these two apps. - If you do not permit access to your location uNav gets positions as expected.

[Bug 1468020] Re: Two GPS compatible apps conflict and loose GPS
Some background first: Applications do not compete or have control over the GPS at all. Location service is handling all of the access. With that, an app is not able to block or exclusively own the GPS. There are multiple other reasons why the apps could appear to not receive any updates, though. That being said: We have problems reproducing the bug on latest rc-proposed images. If someone is able to reproduce, it would be really helpful if we could get gdb backtraces of both apps and the location service. Please see: http://dirac.org/linux/gdb/06-Debugging_A_Running_Process.php for a good overview of how to attach to a running process. Once attached, you should enter "t a a bt full" in gdb, and pastebin the trace(s).

This actually now seems like it's the first GPS app run will keep the GPS and not release it when closed. Try this: 1 Reboot the MX4 2 Open (for example) HERE maps 3 Check it's got your location right 4 Keep HERE open, but choose a different GPS app (eg: OSMTouch) 5 The second GPS app will have your location 6 Move to a new location 7 HERE maps (in this case) will update fine 8 Second app will not update to the new location Even closing the first app before opening the second makes no difference. The GPS is locked to that first app until a reboot is done.
