Hey @mardy, do you know if your background location service implementation has survived the transfer to focal?

Edit: I guess I found the relevant MR: https://gitlab.com/ubports/development/core/lomiri/-/merge_requests/70

@lduboeuf FYI, in Germany there will be another occasion for testing cell broadcast on September 14:

"On the Nationwide Warning Day, a test warning in the form of a warning text is sent to all warning multipliers (e.g. radio stations and app servers) connected to the Modular Warning System (MoWaS for short) of the Federal Government starting at 11:00. The warning multipliers send the sample warning with a time delay to warning devices such as televisions, radios and smartphones. There you can then read and/or hear the warning. "

Wow! FM radio on Ubports would be a dream!

It is for sure not one of the priority devices but could fm radio potentially also work on the S3Neo?
zcat /proc/config.gz | grep -n RADIO_IRIS gives:

2587:CONFIG_RADIO_IRIS=y
2588:CONFIG_RADIO_IRIS_TRANSPORT=y

@libremax Love those pictures. Ubuntu + Ubuntu Touch look great next to each other!

A couple of months ago there has been a short discussions on enabling GPS access for apps in the background (github issue). Currently, there only exists a hacky way to record GPS tracks using the terminal app (forum link).
I completely understand that this issue is not a priority but could you maybe explain in a few words what the technical difficulties or security considerations behind are? Is it a bug or is it a feature? Many thanks to all of you!

@libremax That's what I wanted to say

Cool! Installer support would be amazing! Thanks a lot for all your hard work!

I have gathered some information for experimenting on the FM radio topic with the S3 Neo. After some digging I came across this documentation https://github.com/mer-hybris/hadk-faq#fm-radio. Is it possible that most of the changes can be done on a running device? Or am I getting it wrong?

11 FM radio
11.1 Qualcomm

1. Needs a device with suitable FM radio hardware and a kernel defconfig containing CONFIG_RADIO_IRIS=y (CONFIG_RADIO_IRIS=m if fail to build IRIS_TRANSPORT as module) and CONFIG_RADIO_IRIS_TRANSPORT=m (or =y)
2. If your CONFIG_RADIO_IRIS_TRANSPORT is built-in then this is not needed, however if you have problems try building CONFIG_RADIO_IRIS_TRANSPORT as a module: add (adapt to fit your device if needed) https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/systemd/system/droid-fm-up.service and https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/systemd/system/bluetooth.service.wants/droid-fm-up.service
3. Sometimes device permissions are wrong (root owner), in this case add https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/udev/rules.d/999-droid-fm.rules to your droid-configs repo (or directly to device for testing)
4. Add qt5-qtmultimedia-plugin-mediaservice-irisradio to patterns (or install directly to device for testing)
5. Add https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/etc/pulse/xpolicy.conf.d/fmradio.conf to your droid-configs repo (or directly to device for testing)
6. Starting from Sailfish OS 2.0.2 FM radio Media app plugin jolla-mediaplayer-radio can be added to patterns.

On my S3 Neo running UT, it seems that point 1 and 2 are satisfied:
zcat /proc/config.gz | grep -n RADIO_IRIS gives:

2587:CONFIG_RADIO_IRIS=y
2588:CONFIG_RADIO_IRIS_TRANSPORT=y

Regarding point 3. It seems to me that KERNEL=="radio[0-9]*", OWNER="audio", GROUP="audio" would have to be added since
cat ~/../../android/system/halium/lib/udev/rules.d/70-android.rules | grep radio0 returns:

ACTION=="add", KERNEL=="radio0", OWNER="system", GROUP="system", MODE="0640"
ACTION=="add", KERNEL=="radio0", OWNER="fm_radio", GROUP="fm_radio", MODE="0640"

No idea how to check for the other points.

I know there is no FM radio app in the open store yet but could it work to build something quickly using this https://doc.qt.io/archives/qt-5.6/qml-qtmultimedia-radio.html?

Unfortunately I have no experience in porting yet but if someone could give me a bit of guidance through the steps above, I'd be happy to sacrifice my S3 Neo for testing.

No problem. That was quickly fixed and no data was lost due to the switch

@kugiigi Oh, ok. Thank you!

Hi @c4pp4, I just switched from armhf to arm64 using the installer. But now I have the problem that the openstore crashes when I try to launch it. Is there a way to reinstall the openstore from the command line?

Edit:
I found a way that worked:

sudo -H -u phablet pkcon install-local --allow-untrusted openstore.openstore-team_<VERSION>_arm64.click

And after that reinstalling those apps that crash with the openstore.

For me the fix seems to work. I am travelling by bike since more than a week and a combination of OSM Scout Server, Pure Maps and Utrack does a very good job guiding and tracking me. The error did not occur again.

However, I realized that two fuctionalities would improve Utrack a lot:

• Automatic saving of the track every few minutes in order not to loose the hard work of a day once the battery dies
• A possibility for pausing/resuming the tracking

Do you think this would be possible without deteriorating the battery performance?

Hi @ernest,

I just had a look at the Utrack.py and made the following change (line 183), which made the code run on my phone:

if re.search("^longtide", line): #longtide bug in test_gps
    try:
        long = line.split()
-       if re.match(".\d+.\d+", long[1]):
+       if re.match("(?:\d+(?:\.\d*)?|\.\d+)", long[1]):
            longitude = long[1]
        else:
            subprocess.Popen(["truncate", "-s", "0", temp_file], shell=False)

You are trying to match a floating point number here, right? Following this post it is apparently better to use "(?:\d+(?:\.\d*)?|\.\d+)". I've made a pull request.

I hope this does not break other things. On the my phone it works..

Here is the click if someone wants to test:

Best,

Thanks a lot for your work!!!

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'

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?

@Flohack Yes, MMS in and out works!

Thanks to @Flohack, @Nandell, @Speiburger, ... I also managed to install Ubuntu Touch on the S3Neo. Here is a short summary of the steps that were necessary: https://pad.ubports.com/p/k6P5Z9kPu1R5t_ocx3J-
They closely follow @Flohack's description on top of this thread.
