uNav GPS not working
-
@flohack Thanks for you kind answer, but how should I know what valid/invalid data looks like?
Whats the difference between
*** location callbackand***nmea info?
The*** location callbackprovides a latitude, magnitude and an accuracy of 10.000.
Its prints some coordinates. Sometimes thenmea (nr):rows have some empty fields,,but not always. -
@jimmypesto
with my 2 N5 it is exactly the same... if I install LineageOS ( https://sourceforge.net/projects/hammerhead-lineageos/files/17.1/ ) both work fine ( only with GPS ) ...( with Ubuntu ) if it has found the location it goes faster afterwards. But when you restart the device, the whole procedure starts again...
Best regards

@manjushri thanks for your feedback.
May I ask how long it takes to initially get your location on these devices and where/how you place them to find it?
-
Are there devices that are known to have a quicker GPS localization?
I love this OS so much and it would be awesome to find a solution I could rely on. Thanks for your help.
Edit:
I was able to run
test_gpsand see changes in my position while walking outside in less then 5 min.I start to feel like I have a different problem with my OP1. I do not know if they are related but to sum up:
- rotation does not spin the display (even though lock is disabled) which worked before
- SensorStatus App is not able to access any of the sensors available on my device, some worked before
-
@jimmypesto Yes Oneplus 1 has a bug that the Android sensor API crashes from time to time, so you wont have any rotation, light, proximity etc sensors working. Very annoying but hard to fix.
You may want to wait for a few weeks as we are finishing the port for the Android 7.1 base, that might be more stable.
Regarding GPS, it could be a similar issue, but not sure. GPS is independent from sensors API
-
@flohack You guys are doing awesome. Thanks for the info. Just donated to this project again.
Do you know the difference of how test_gps gets sensor data to the way apps do? Because I was able to somehow proof that test_gps seems to work.

@jimmypesto
you're welcome, I do not have an optimal location, hills and mountains , but it works. Put the device outside on a wooden post. The first time takes 10-25min with my devices....
then 2-3 min ... the better the reception the faster... but if I uNav a few days not use it needs again 10-25min or it finds nothing more, then only helps to reinstall the app ... so I have already installed 4 times LineageOS to see if it works, it always worked fine even over time ( only GPS ) .
possibly this is also a possibility, had a friend of mine ... https://www.youtube.com/watch?v=CvIiNXf-NKo -
@manjushri at least it sounds like a nice location besides hills and mountains
Nice thanks for that info's! I will give it a new try after reinstalling uNav.
-
@jimmypesto its fed into Qt location API via a custom Qt module and the platform API which in turn tries to get Androids location API. But that part did not change for a long time, I dont see a reason why test_gps would work, but location wouldnt, tbh. So I am out of ideas ^^
-
@flohack I see.
I will need to setup a fresh system I guess. -
Initially I did a full factory reset on the phone. After installling Pure Maps again it did not Work. It was not even listed in the GPS settings. Also SensorStatus and uNav failed to access GPS.
I then decided to install the full system again with the awesome UBports Installer. Initially I wasnt sure how to do so as I found no documentation without running Android on the phone. But it was as easy as expected. I enabled Dev.-Mode from the phones system settings, started the installer and booted into recovery ...
I went back to the
stablerelease to be save.
SensorStatus does not longer print any errors in the GPS tab. Still none of the other sensor tabs is able to provide data. Also the screen rotation feature is not working. What should I do about this?
BUT within less then 10 min. I had a valid GPS position in Pure Maps! Awesome!
I will do futher tests in the next days. -
so, I have my 2 devices 3 days ago freshly installed, 1x rc - channel and 1x devel ( wipe, bootstrap and format system part. , with installer 0.8.2-beta ) since then runs uNav on both devices well, the first start about 7-10 minutes then 1-2 minutes and location is detected
... hope it stays like this... -
Yes I can confirm again the first fix is done in less then 10 min and afterwards its even faster!
A fresh installation after over one year of usage was a good idea.[Edit]:
Rotation sensor started to work too. Within SensorStatus and display rotation. Awesome! -
How can I mark this as solved? Sry I am blind...
-
@JimmyPesto Topic Tools (cog wheel, bottom right) ask as question, then mark as solved. Any problems let me know.

@lakotaubp thx!
