Cannot send files via bluetooth

[JulesD]

I'm using Debian 12 and have installed the necessary packages for bluetooth, including blueman. I can connect to my bluetooth speaker but when attempting to send a file to it I get the error message from blueman : "Unable to find service record" and the file isn't sent. Any suggestions? Thanks in advance for any advice.

Please post the output of

Code: Select all

systemctl status bluetooth

[JulesD]

Hi Hallvor, thanks for the response. The output is:

It looks fine so far. Let's see some log entries:

Code: Select all

# journalctl -u bluetooth.service

Edit: I found this. It may be related to insufficient permissions on the remote device: https://askubuntu.com/questions/145767/ ... to-another

[JulesD]

There's no output from the journalctl command.

Regarding your link, not sure how or if it's even possible to set permissions on the speaker. I don't think it's necessary because it works fine sending a file from my portable mp3 player.

The issue was raised on the blueman github pages a few years ago.
https://github.com/blueman-project/blueman/issues/996

[Hallvor]

There's no output from the journalctl command.

There should be. Have you disabled logs?

[JulesD]

No. How can I check if they're disabled?

[JulesD]

Ok, my mistake; I mistakenly included the hash symbol when copying the command. The output is:

Hint: You are currently not seeing messages from other users and the system.
Users in groups 'adm', 'systemd-journal' can see all messages.
Pass -q to turn off this notice.
-- No entries --

[Hallvor]

# means that the command must be executed as root (or sudo)
$ means that the command should be executed as regular user

Oh, and what do you mean by "send a file to it"? You mean play music, I assume, and not physically sending a file to a speaker?

[JulesD]

Ok, thanks. Yes by "sending a file" I mean play music.

So here is the output of journalctl :

[sunrat]

In Debian 12 using Pipewire, you need libspa-0.2-bluetooth for bluetooth audio. See the wiki - https://wiki.debian.org/PipeWire

[JulesD]

Hi sunrat, I installed the pipewire meta-package as recommended but it hasn't solved the problem... or maybe you weren't suggesting that it would?

[Hallvor]

The error message "Protocol not available" suggests that the system is having trouble finding the appropriate protocol for audio streaming. It looks like a compatibility issue.

Does this work?

Code: Select all

rmmod btusb
rmmod btintel
modprobe btintel
modprobe btusb

Thanks for trying to help, but it's not really a big deal and I have better things to do, so I'm giving up.

Heh - this happens a lot with Bluetooth. It's so arcane that most just give up. I guess that's how you separate the men from the boys in Debian? If you see someone using Debian to play music through a Bluetooth speaker, should you: a) ask for his autograph?, b) fall to your knees before him and bow?, c) grovel and ask for help to get your system configured? One thing is for sure: You will not find the information required in the documentation. LOL
