First of all, don't use sudo.

What is your Bluedevil version? Can you please post complete terminal output when trying to pair device?

Hello I am able to pair my bluetooth microsoft keyboard 6000. However I am unable to pair my SoundLink on-ear Bluetooth® headphon. I had these earphone phone working before but unfortunately I cleared my paring and not can't pair it.

I do see my 'Bose OE SoundLink' in the bluetooth wizard, when I select it times out and nothing happens.
Comment 4 Rajinder Yadav 2015-09-12 17:13:10 UTC
Update: My bluetooth disappears on a reboot so I am forced to add it again. My bose headphone still not working.

I now have 2 keyboards a usb and a bluetooth one. I don't know what happen to Linux and KDE but ever since the last release it's been really aweful!

Things that use to work don't, I spent countless hours on google looking for solutions, fixes take forever or just don't happen. It feels like the quality has become sloppy these days from KDE. I want my Bluetooth working. I've had countless of other issues with KDE/Linux and I am almost at the point of giving up on KDE.
Comment 5 Rajinder Yadav 2015-09-12 17:14:18 UTC
Correction should say my bluetooth device (keyword) disappears...
Comment 6 David Rosca 2015-09-12 17:17:53 UTC
I'm sorry about your experience, but this problem is only because Kubuntu (as the only distribution nowadays) still don't use BlueZ 5.

BlueZ 4 support in KDE is really old, buggy and not maintained for a long time.
When you update to BlueZ 5, I believe you will be pleased with state of Bluetooth support.

Unfortunately, there is nothing I can do to help you. And please don't blame us for this issue, it's really not our fault.
Comment 7 Rajinder Yadav 2015-09-12 17:31:39 UTC
Thank for your reply, I will look into installing BlueZ 5 on my system.
Comment 8 David Rosca 2015-09-12 17:37:32 UTC
Just for the record, you will then need either Bluedevil 2.1 for KDE4 or any recent Plasma 5 version of Bluedevil.
Comment 9 Rajinder Yadav 2015-09-12 18:16:29 UTC
I reinstall the bluez 5 from source after removing the old bluez package from my system. I also install my system bluedevil package but nothing seems to be working. Do I have the right version of bluedevil?

Comment 10 Rajinder Yadav 2015-09-12 18:27:24 UTC
I am back to square one, bluetooth keyboard work, stop working on reboot, headphone don't work at all.

How can I get KDE to detect my bluetooth devices and remember my settings? Is it not capable of even doing this. This is kind of lame.
Comment 11 David Rosca 2015-09-12 18:28:54 UTC
You still have Bluedevil 1.3 which is for KDE4. I can't guess the version of BlueZ from the syslog output, but if it worked with Bluedevil, then it must still be BlueZ 4.
Comment 12 Rajinder Yadav 2015-09-12 19:04:57 UTC
I feel like I am going around in circles, I have Kubuntu 15.05 installed so I already have Plasma 5. My KDE Plasma version is 5.2.2. So does it not come with the latest bluetooth modules? 
Like bluez 5 and bluedevil?

In any regards I install bluez 5 from source, so what's wrong? You keep telling me I have the wrong versions installed. Can you please tell me how to check the version for the bluetooth stuff so I can get it working again?
Comment 13 David Rosca 2015-09-12 19:51:57 UTC
Bluedevil must be Qt 5 (KF5) based and in your case version 5.2.2, as the rest of Plasma.
BlueZ must be 5.xx version, and you should be able to check it from syslog:
