Cannot use bluetooth

05 February 2023, 22:19:05

I have bluez blueman bluez-utils bluez-dinit bluez-tools installed and the bluetoothd service is enabled.
From my Artix device I cannot see the other device.
The other device can see Artix and connect.

On Artix in blueman-manager it shows it connected but "Send File" is grayed out.
And I cannot send a note: "Unable to find service record".

/var/log/errors.log:

This looks like a library break with connman which is strange since it is in the package directly.
Try rebuilding connman and see if the library break error is repaired.

Code: [Select]

$ git clone https://gitea.artixlinux.org/packagesC/connman.git

Isn't that error related to some vpn daemon?
I put all the /var/log/errors.log file there.

Saw someone complained about bt broke after python-cairo and cairo packages upgrade. Try downgrade those two see if that quick fix helps.

Just rebuilding the python-cairo package will address the current python issue.
My python applications ran after installing the local build.
Or some users went to the AUR git version which also addresses the issue.

The executable is directly from connman.

Code: [Select]

$ pacman -Ql connman
connman /etc/
connman /etc/connman/
connman /etc/connman/main.conf
connman /usr/
connman /usr/bin/
connman /usr/bin/connman-vpnd
connman /usr/bin/connmanctl
connman /usr/bin/connmand
connman /usr/bin/connmand-wait-online
<... snipped ...>

The error message shows library breakage occurring.
When I see a library break, I start building the package to see if addresses the issue.
Most of the time it will fix the issue though a few times a linked library or very rarely libraries needed to be redone as well.

I also have the same bluetooth errors you posted in "/var/log/errors.log":

Code: [Select]

Feb  8 08:28:21  <server name> bluetoothd[877]: src/plugin.c:plugin_init() Failed to init vcp plugin
Feb  8 08:28:21 <server name> bluetoothd[877]: src/plugin.c:plugin_init() Failed to init mcp plugin
Feb  8 08:28:21 <server name> bluetoothd[877]: src/plugin.c:plugin_init() Failed to init bap plugin

My bluetooth works with these posted failures though with network-manager's applet.

What version of pyhton-cairo should I try?
I have "world/python-cairo 1.23.0-2 [installed]".

I reinstalled connman I will check errors.
But shouldn't that error be a problem for a vpn only?

The latest update today for me is now at world/python-cairo 1.23.0-3.
Just update and it should be good if you have not already.

Blueman-manager now needs to be build and linked to the newer python-cairo application.
Updates can be frustrating to be sure if all the packages are not at the same level at the same time.
The best way I find for myself is to compile the packages locally if I need it right away to address the API/library/linkage breaks.
Otherwise I just wait until the distribution releases the fixed package in question.

On another Artix device blueman-manager was able to see BT devices but not my Linux phone.
The phone could see it and connect but same error: "Unable to find service record" and I couldn't do things.

After updating it is the same but the phone cannot see it anymore.
It is working fine with a BT headset.

So maybe something went wrong when updating on the 1st device?

I am glad the bluetooth headset connected, it shows that you have a functioning setup.

When one device does not connect but others do this sounds like an encryption/protocol version situation.
Kind of like each device is speaking in it's own language resulting in a lack connectivity.
One would have to research the device on what bluetooth versions work with it and if there are work arounds/procedures for the stated device.
It could even mean purchasing new hardware to get the connection to go.
If the device has hard encoded firmware, usually the only solution to incompatibilities would be new hardware.

On the first Artix device I cannot use the BT at all.
It was working on another Linux.
And my phone used to work on both Artix devices, but not on Artix.

1st device:

Code: [Select]

rfkill 
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

Update first device with realtek card can use the BT speakers.
I can see my other Artix device but I cannot send a note let alone a file.
