Now it's like the OS doesn't 'grab' the bluetooth. When I boot rfkill starts with a softlock but I imagine maybe it's just now the default after installing the package. Maybe it's just my configuration. It's not something I messed with before but now I am paying attention to it.
Not sure anyway to fix this without nuking the setup.

I'm using a t400 running libreboot.

It works fine at least for mice and keyboards.
Thanks for init freedom

I use bluetooth for android (lineageos) file transfer and for 3 different BT speaker sets. Eveything works.

I don't know if bluez 5.55-3.1 will run on testing or if the problems mentioned are hardware-specific for all versions. Maybe someone wants to try package the latest source.

Re BT speakers/headsets: there was a thread here for those who don't want pulseaudio (bluez-alsa)

https://dev1galaxy.org/viewtopic.php?id=4612

I finally sorted debian sid packages' missing sysv script for bluez-alsa. The rebuilt debs do work in chimaera (can't test on Daedalus yet) :

https://exegnulinux.net/apt/pool/main/b/bluez-alsa/

The trouble I have is the Headset connection is dropping audio far too much,

and pulse audio won't show or switch to it on connect after the very first time.

I'm trying a few hacks but have no joy yet.

and this page... http://askubuntu.com/questions/366032/p … omatically
but it's still really flakey
the BT icon shows up in the system tray, and connects when paired, but pulse won't change over. I have also blacklisted
manually at each boot with rmmod in rc.local "rmmod -f snd_hda_codec_hdmi" to get rid of the useless hdmi audio connection (seems to be set for laptops) on my desktop system . Thank you</edit>

...watching with interest. (although I am running devuan_chimaera)

<edit>
I'm trying this with Pulse-audio... on a desktop with outboard usb-audio and hdmi module removed through rc.local

I had to install 2 include files to compile the binary :
sudo apt install libical-dev libreadline-dev

Then : ./configure --disable-systemd --disable-udev
Then : make

In my last message about the bluetooth bug in Daedalus, I only found a workaround to make bluetooth work on my Devuan Daedalus installs.

I noticed that some Linux distributions have the new version of the bluetooth stack (5.64), for example OpenSuse 'TumbleWeed', unfortunately with a dependency to systemd. So I looked for the 'official' source code of the latest version (5.64) and found it there : http://www.bluez.org/

Release of BlueZ 5.64
19th March 2022, 06:18 am by Tedd Ho-Jeong An

This is another release mostly with the bug fixes on HOG, GATT, A2DP, Media, AVDTP, AVRCP, and scanning failure. Also, this release includes a fix for building with old glibc (< 2.25), and other minor issues found with the static code analyzing tool. ISO packet support is added to the emulator as a part of LE Audio development.

Source code from : http://www.bluez.org/
Tarball : http://www.kernel.org/pub/linux/bluetoo … .64.tar.xz

I downloaded the tarball and examined its 'autotools' scripts and configuration files.
Looking at the source code from the tarball in the (autotools) configure.ac file I saw the possibility to get rid the dependency to systemd with the '--disable-systemd' argument to pass to ./configure, so I decided to try to compile the source code.

I had to install 3 include files to compile the binary :
sudo apt install libudev-dev libical-dev libreadline-dev

Then : ./configure --disable-systemd
Then : make

In the src dir, the 'bluetoothd' daemon is built.
In the obexd/src dir, the 'obexd' daemon is built.

obexd => OBEX(OBject EXchange) daemon. OBEX is communication protocol to facilitate the exchange of the binary object between the devices.

I moved the two daemons to the /usr/libexec/ after renaming the old files.

I rebooted my Devuan 'Daedalus' ThinkPad laptop and ;o)

I think it is possible to integrate these two binaries and maybe build a fully working up to date package for Devuan Daedalus. I'd like to contact someone of the Devuan programmers to do this.

Within a few days, I'll know if the new daemons are bugs free and investigate a bit more...

Thank you for 'init freedom' : )

bluetoothd version 5.62 maybe needs to be debugged and repaired.

Yeah, maybe. Some of these bugs go back to 2009. I can't tell from this page if they're unfixed or if they just don't ever close their bug reports.
https://bugs.debian.org/cgi-bin/pkgrepo … kage=bluez

Thanks for the info. Someone else may run into the same problem.

What I wrote previously :
I first installed Chimaera and Daedalus (older ISO) on qemu/kvm virtual machines, easy stuff and no problems!
Then I installed Daedalus on two laptops - a ThinkPad x270 and a ThinkPad 13 2nd gen.
It's a preview and I had some difficulties with partitioning and the network while installing but finally succeeded.
Once installed, Daedalus runs perfectly except for the bluetoothd/bluez service. From time to time it stops and I have to restart the service. The mouse I use works flawlessly with Debian testing, so I believe there's something wrong with Daedalus Bluetooth implementation. For example, when I put my mouse off the Bluetooth service stops.
I've been using Debian testing for years on my computers (DE=Xfce) and Debian stable for my Web server and I intend to switch to Devuan. I'll install Devuan on other desktops and laptops, old and new.
For now I use my 13" ThinkPad with Daedalus installed and except for the Blutooth (5.62) problem I'm very happy with Daedalus.
Thank you for 'init freedom'!

I found an immediate solution for the bluetoothd problem that I found while enjoying Devuan Daedalus on two laptops.
I extracted the bluetoothd daemon executable file from Chimaera's bluez_5.55-3.1_amd64.deb package and put it in /usr/libexec/, replacing the 5.62 version.
And it works now.o I believe that Daedalus bluetoothd version 5.62 maybe needs to be debugged and/or repaired.
Hope it helps.
Thank you for 'init freedom'
