To have the recording screen off, you have to enable with Tweak tool the option "Prevent suspend" for the terminal app.

As I wrote, I already enabled this setting.

One thing I didn't mention is that I don't have a SIM card in yet, my Android phone is still my main phone until I migrate everything to the OPO. I didn't have any Internet access. I since read that GPS localization seems to be more problematic without a SIM card.

Check the new version, uploaded today, no more long list the screen is refreshed after each datapoint.
I've also add a sum-up calculation at the end :
GPX file Created : 1566872659557.gpx

    Length 2D: 0.004km
    Length 3D: 0.016km
    Moving time: 00:00:11
    Stopped time: 00:14:34
    Max speed: None
    Avg speed: 0m/s = 1km/h
    Total uphill: 3.3m
    Total downhill: 4.3m

That sounds great, I'm back home and with still a week vacation left, I'm hoping to test this further. Thanks!

I wonder, can we install Git on UT? It would make updating your script easier. I think I'll try and see.

A word of warning: if you forget to activate the terminal's "prevent app suspension" button, once the script is launched, there is no stopping it!!! The CTRL+C button at the bottom will not stop the script.

I meet the bug, doesn't appear on Edge but on Devel Yes.

I'll look at it.

normandc

Sorry, I guess I should have mentioned I'm on 16.04/rc.

BTW I tried to install git on UT, the package isn't available. I guess I could always git pull from my PC then copy to the phone, but I'm not seeing the gps-utouch-tracker folder from the PC, only the folders Documents, Music, Images and Videos...

@normandc
From the phone terminal,

wget https://framagit.org/ernesst/gps-utouch-tracker/-/archive/master/gps-utouch-tracker-master.zip && unzip gps-utouch-tracker-master.zip

normandc

@ernest thanks, I guess keeping the original folder name (with -master) will make updating easier in the future.

All, i'm looking for good soul to test the last version, please contact me on Telegram : @Ernes_t

I've updated the script to : Consume less battery, import automatically the run to Activity Tracker when finished, upload the position in real-time to Phonetrack (Nextcloud) and distributed into a click.

I found recently thanks to iperspace, apparmor hack, the script should be able to run under all version.

Thank you all for this subject !
Is there a description (or source code) of the test_gps command somewhere, please ?

Hi all,
I think this app is very useful.
However, I can’t make it work.
I use an Aquaris E4.5 with ubuntu 16.04 (OTA11).
I used the previous script and now the recent updated script with no luck.
I have no issues with the installation, but when I launch the script, it gets stuck with “Waiting for satellites ...”.
When I close the app (Ctrl+C), it creates an empty gpx file.
The rest of apps (ActivityTracker, OSMScout) fetch the data and show my position, so I am sure that GPS is working properly.
What could be the cause?
Thank you for your suggestions.

@aimar
i noticed that the script is neither working with OP3 device. I had to modify it to make it works.
Are you on telegram, if so please contact me @ern_st

Hi there,
Thank you @ernest for your work. Background GPS tracking is one of the features that I am missing most on Ubuntu Touch!

I tried to make it work on my XperiaX and my Nexus 4 but unfortunately without success. After a short while the following error is returned:

Waiting for satellites

Traceback (most recent call last):
  File "./Utrack.py", line 317, in <module>
    read_gps(p)
  File "./Utrack.py", line 219, in read_gps
    if 70 > ACCURACY > 0 and len(longitude) > 0 and len(latitude) > 0:
TypeError: unorderable types: int() > list()

Utrack_log.txt is empty but in the Utrack_tmp.txt I can see that the satellite data seemes to be logged correctly. The location is correct. I X'd out the exact position:

*** location callback
flags:  55
latitude:       50.XXXXX
longtide:       4.XXXXXX
accuracy:       23.000000
utc:    -758278816

The error appears strange to me since none of the inputs is a list. Do you have a clue what to do?

ernest

Yes likely, it has register a list and now it tried to compare it with a int.

I've another version in WIP, that should fix that ...but has other bug. I'll try to find the click.

Edit : Try this one : https://drive.google.com/file/d/1I-_nGDVoFy5hdqiR_ApuA4hKCk8qmqSo/view?usp=sharing

Hi @ernest!

Thank you for the quick response. Unfortunately I've another error now:

Traceback (most recent call last):
  File "./Utrack.py", line 350, in <module>
    read_gps(p)
  File "./Utrack.py", line 177, in read_gps
    event = event.decode("utf-8")
AttributeError: 'TailEvent' object has no attribute 'decode'

ernest

@hsce1 yep i've this thing once every 20 usage...I'll troubleshoot this summer.

hsce1

Thanks a lot for your work!!!

How did you get GPS tracking work? I got the program running in the terminal, but it seems to have no access to the GPS. The symbol in the indicator bar remains black.

In the description there are requirements mentioned (which I can not fullfill):

Depending of the Ubuntu Touch version and AppArmor security, you might need to run this app into an iperspace. See https://open-store.io/app/iperspace.emanuelesorce Currently RC and Stable requires this tool.

What do I have to do with this link/Information? I get a page: The app you are looking for has been removed or does not exist ...

ernest

@herr-b You have to allow the terminal to run in background.
This app use test_gps which bypass Lomiri thus the icon color.

You can ran manuall in the terminal test_gps

However this app will likely not work for pinephone and Halium9.

herr-b

@ernest Yes I already allowed the terminal to run in the background.
test_gps shows 'init gps interface' and the program shows 'Waiting for satellites' but both get no position, while Pure Maps has GPS reception and shows the position on the map. Foreground or background doesnt matter. It looks like the terminal does not get access to the GPS?
I switched from stable to RC without any change. I use it on a BQ Aquaris E4.5 Ubuntu Edition.
