Bluetooth Issue on ThinkPad T450s
I am trying to bring up bluetooth device on my ThinkPad T450s. The laptop is dual booted with Windows 7 and I can see the bluetooth device listed under lsusb. However I cannot power it up.
I have already installed bluez and tried rfkill unblock. User is already added into lp group. Nothing changed in default configuration file.
The things I have tried are:
$ uname -a

Any help is appreciated.

Re: Bluetooth Issue on ThinkPad T450s
I had the same problem when I upgraded to linux-4.5.1-1 and now also to 4.5.2-1. So at the moment I use the kernel version 4.5-1 and I have no problems with bluetooth...

Thanks a lot for reply.
When I first tried to use bluetooth I was already using 4.5.1-1. but the other post I quoted which had the same problem as mine was posted last year.
so I guess should try lts kernel?

I don't use linux-lts, but this: http://seblu.net/a/archive/packages/l/l … pkg.tar.xz and http://seblu.net/a/archive/packages/l/l … pkg.tar.xz
then,
sudo pacman -U /path/to/linux-4.5-1-x86_64.pkg.tar.xz /path/to/linux-api-headers-4.4.1-1-x86_64.pkg.tar.xzHowever, if after the downgrade of the kernel, bluetooth still doesn't work install/reinstall the following packages and reboot your system.
sudo pacman -S bluez bluez-utils pulseaudio-alsa pulseaudio-bluetooth bluez-libs bluez-firmwareHope this helps

Thank you for the advice.
I have tried the older version and zen kernel. None of them worked and they just gave the same output as before.

Re: Bluetooth Issue on ThinkPad T450s
I wrestled with how to turn on bluetooth for several hours on my Thinkpad T420.
If anyone in this thread mentioned which software method is used to connect to their wifi, I missed it.
I use connman, which turned out to be the key to getting bluetooth to power on and connect for me.
After a fresh Arch install on the new SSD drive, neither wifi or bluetooth would power on. I installed rfkill and was able to get wifi going with
sudo rfkill unblock allBluetooth remained soft blocked after issuing that command as shown using
sudo rfkill list allWhile I don't remember where I found the next command, I made a note to self about it. It may be in the Arch Wiki.
connmanctl enable bluetoothAther running that command, wifi and bluetooth are fully unblocked.
[me@ar64-ssd ~]$ rfkill list all
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
[me@ar64-ssd ~]$Now wifi and bluetooth are powered on at boot time, so it's persistent.
Next stop was bluetoothctl (install bluez bluez-utils. I also grabbed bluez-libs-5.40-1 pulseaudio-bluetooth-8.0-3 bluez-firmware-1.2-8
I don't know if all of them are needed - I'm still trying to direct audio output to a bluetooth speaker. Now I can connect to the speaker using
$ bluetoothctl
[bluetooth]# scan on

[Jam Plus]# It appears in that last line that Jam Plus is ready to receive, and it gives an audible "ready" signal. I just don't know to send audio output to it yet. I'm using Rythmbox, have pulseaudio-bluetooth and alsa-utils installed, so I think I'm close to my goal.
At least now I can connect to the bluetooth speaker.
Hopefully, the steps I have taken to enable and connect Bluetooth will help someone...
Edit: Got music output to my bluetooth speaker. Installed pavucontrol, but I question whether it's needed. I couldn't get sound unmuted using pavucontrol (a simple GUI).
I found this page in the Arch Wiki, https://wiki.archlinux.org/index.php/Pu … leshooting - the Pulseaudio troubleshooting page - and these commands
[me@ar64-ssd ~]$ pacmd list-sink-inputs
pacmd set-sink-input-mute <index> falseMy speaker's index number listed as "1", so using that in the second command in place of <index> I now have bluetooth sound.
Bluetooth is easier in other distros, but I learn something everyday using Arch Linux.
Cheers!

Re: Bluetooth Issue on ThinkPad T450s
I could not power on bluetooth, too. I have a T540p with Manjaro. Switching the Kernel helped. 4.8 and 4.4 did not work, 3.10 and 4.1 worked.

Re: Bluetooth Issue on ThinkPad T450s
I think it is a systemd problem.
On Funtoo installation with openrc service manager and debian kernel 4.7.8, my bluetooth on T450s works without any issue.
I love archlinux: the last STABLE kernel release + the last STABLE DE release + the last STABLE apps releases. The upstream developers decide what is STABLE.

Re: Bluetooth Issue on ThinkPad T450s
delta67:
You man want to try this.
I have the exactly error you had. I install another package: pulseaudio-bluetooth.
you can refer to:
https://wiki.archlinux.org/index.php/PulseAudio
The reason that it happened may be that pulseaudio's packages has been splited from main package, some splited extra packages didn't install, so bluetooth failed.
