Trying to revive 'ubtd' (Bluetooth file transfer)

PhAndersson

Final status update: the app has passed the code review and v0.1.1 is now available on the OpenStore.

You will find it under the name "Ratatoskr (Bluetooth file transfer)", in the "Utilities" category.

If you install it, may I suggest that you check the README here: https://github.com/petroniusniger/ratatoskr/tree/main for a brief description of how to use it most effectively?

Also, should you discover any bug, please report them here: https://github.com/petroniusniger/ratatoskr/issues

@PhAndersson Not tested yet. But thank you for your work and perseverance.

@PhAndersson Should the app be shown in UT TT apps ? I don't see anything on my Volla 22. What should be the names of the cache config data directories ?

I'm sorry, I guess I'm a bit slow tonight, but I'm not clear on what 'TT' means in this context. Can you clarify?

What should be the names of the cache config data directories ?

The app cache is in ~/.cache/ratatoskr.petroniusniger/. This is where incoming files are kept -- but there is no config data there (the app doesn't store any configuration data at this stage).

@PhAndersson UT Tweak Tool https://open-store.io/app/ut-tweak-tool.sverzegnassi

PhAndersson

Sure, Tweak Tool, of course -- sorry.

I just checked on my phone and it shows there, yes. Just look under the name 'Ratatoskr' (that's the actual name I gave the app -- "Bluetooth file transfer" is only a description).

It's the first UT app I built, so I'm not familiar yet with all the intricacies of the dev. workflow.

In any case, it seems there was a mixup, as the packages that were pushed on the server are v0.1.0, not v0.1.1. The "file sending" functionality may not be functional in that version (the receiving one should be).

I'll try to get this fixed tomorrow.

PhAndersson

I need to amend the statement above. After further tests, the code that has been used to generate the packages is the correct one, so all the latest functionalities are present, and both sending and receiving files should work.

The only problem is that the wrong version string has been used when building.

@PhAndersson Can connect with bluetooth a Volla with Volla OS to a Volla 22 with UT noble. Try to send a little video from Volla to Volla 22 following the procedure. But doesn't work currently. File not sent / received.

There is currently a bug in Noble (up to 24.04-1.2) that prevents the OBEX daemon from starting.

The fix exists and is already merged. Here is the related MR: https://gitlab.com/ubports/development/core/ubuntu-touch-session/-/merge_requests/81. It is supposed to be part of the upcoming 24.04-1.3.

Based on earlier tests by @gpatel-fr, once this fix is available, 'ratatoskr' should work on Noble as well.

@PhAndersson

yes that's it.
@domubpkm
you can add the fix even on stable with a systemd overlay file.

phablet@ubuntu-phablet:~$ systemctl --user cat obex
# /usr/lib/systemd/user/obex.service
[Unit]
Description=Bluetooth OBEX service

[Service]
Type=dbus
BusName=org.bluez.obex
ExecStart=/usr/libexec/bluetooth/obexd

[Install]
Alias=dbus-org.bluez.obex.service

# /usr/lib/systemd/user/obex.service.d/ubuntu-touch-session.conf
[Service]
ExecStart=
ExecStart=/usr/lib/bluetooth/obexd -P ftp,irmc,mas,pcsuite -r $HOME

# /home/phablet/.config/systemd/user/obex.service.d/xxoverride.conf
[Service]
ExecStart=
ExecStart=/usr/libexec/bluetooth/obexd -P ftp,irmc,mas,pcsuite -r $HOME

after adding the overlay, you have to restart the obex service using systemctl --user restart obex

@PhAndersson @gpatel-fr So the fix is in 1.3 daily. Wait 1.3 candidate to test. Thanks.
