bluetooth no file transfer

Hi.
Since several updates ago I cannot transfer files by bluetooth. Only call and audio. From other MXlinux installation I can transfer files so it seems the problem is somewhere in the tumbleweed configuration.
Mpow BH456A dongle. Chipset rtl8771 or 8761 for the Mpow driver (outdated from Dec. 2020):

Thanks.

@sidler_bot:

Please check the output of “rfkill list” – it’s possible that, the Bluetooth interface has been blocked.

It was software blocked. But after



rfkill unblock bluetooth


file transfer still not working. Maybe i need to find a working driver, but not sure where because Mpow doesn’t update the driver since 2020.
Thank you.

I had exactly the same problem on two machines but with different Bluetooth chipsets (one of them is Intel).

The problem started when bluez was updated to version 5.62. So at the moment I use bluez 5.61 and libell0 0.44 to circumvent that problem.

Hi. How can I downgrade to those versions? I can’t find the packages.

Try to use bluez 5.63: http://www.bluez.org/release-of-bluez-5-63/


zypper addrepo https://download.opensuse.org/repositories/Base:System/openSUSE_Tumbleweed/Base:System.repo
zypper refresh
zypper install bluez

I installed that .63 version but no systray icon for bluetooth. Looked for blueberry and it’s now in a separated repo. Installed then blueman but file transfers still not working.

I didn’t try to deal with those firmware issues yet.
Thanks.

This is a little mess. Seems obex.service doesn’t exist. But too complicated for me to fix. could be it fixed and leave all the services running? Sometimes you need to transfer files by bluetooth.

and what about this:
Unable to autolaunch a dbus-daemon without a $DISPLAY for X11
is it supposed obex should be working by default in tumbleweed because is important?. why in my system are the things messed (for me as a normal user) this way?.
thanks.

Hi.
Could someone who can use blueman to transfer files to his phone (maybe better if a samsung) with no issues leave here a list of services running and related to obex, bluez, and dbus?
Thanks.

As i already stated in post #5 I discovered the same problem as you and my current workaround is to use bluez 5.61 and libell0 0.44 to circumvent that problem.

I was lucky to lock those packages so that I still can use them but I have no idea where you could get those packages from. They are no longer available at https://download.opensuse.org/history/.

However I just searched bugzilla and found this what sounds quite similar to our problem.

And on my system /home is a symlink. So i will try the fix mentioned by the bug-reporter.

Regards

susejunky

The bluez package was split a while back:

$ rpm -q --changelog bluez | grep -C 1 obex
* Tue Nov 23 2021
- Stop nuking the obex service, we support user systemd services
  just fine now. Following this, no longer hack the dbus service,
  leave it as a systemd service as upstream intended.
- Split out obex in own package with it's needed enabledment as a
  systemd user service.

To fix this in TW:


$ sudo zypper in bluez-obex
$ systemctl --user start obex

Auto start doesn’t seem to be working, so a bug report is warranted.

This was helpful!

Although in the meantime after installing the latest bluez version I had already discovered that a package bluez-obex was missing and I installed it. But I had not sorted out yet how to get that service started.

Could you please share a link to that bug report so that i can remove my own “auto start mechanism” as soon as the problem is solved?

Thanks a lot.

Regards

susejunky

Finally I spent some time on this and I have good and bad news. The good is I got it working. The bad news are I don’t know how I did it. :shame:
you know, after visiting several links to pages and forums with information I got it. I’ll try to find out how, but now I leave here the links just in case anyone can fix this problem with them.

this instruction that created a symlink from dbus-org.bluez.obex.service to obex.service:
[LEFT]sudo systemctl --global enable obex
or the export DBUS_SESSION_BUS_ADDRESS=/run/user/$(id -u)/bus

because  in my system /usr/lib/systemd/user/dbus.socket doesn't look for  .../dbus/user_bus_socket but only for bus (in /run/user/1000/)

actually I have duplicate dbus.service and dbus.socket files in these two locations:
/usr/lib/systemd/system/
/usr/lib/systemd/user/
and obex.service is in:
[LEFT][FONT=sans-serif]/usr/lib/systemd/user/[/LEFT][/FONT]
[/LEFT]

hope this helps, and thank you very much to everybody.rotfl!

Now transfer of files to the phone via bluetooth is working properly with bluez 5.64-1.9, blueman 2.2.4-41.1 on xfce 4.16.4 and kernel 5.17.4-1. [size=4]I leave here what I found out after a little researching:

and rfkill must show bluetooth as unblocked:


[14:01][da@:~]$:**sudo rfkill**
ID TYPE      DEVICE      SOFT      HARD
 0 wlan      phy0   unblocked unblocked
 1 bluetooth hci0   **unblocked unblocked**

Finally I got this fixed. Many thanks :’(

An update here because after a fresh install file transfers via bluetooth didn’t work again:

$:sudo zypper in bluez-obexd (obexd wasn't installed).

and I needed to enable and start it:
systemctl --user start obex.service
systemctl --user enable obex.service

sometimes if it doesn't work:
- disconnect and delete the device from the  devices window (bluez applet/devices).
- switch off bluetooth.
- switch off bluetooth in the phone too.
- start the pairing process again: switch on both  bluetooths, search for devices, connect/pair...

Current installed versions:
bluez 5.69-1.1
blueman 2.3.5-1.4
kernel 6.5.3-1-default
xfce 4.18.4

It still working fine:
kernel 6.6.3-1-default
bluez 5.70-1.2
blueman 2.3.5-1.5
xfce 4.18
