Bluetooth not working

My embedded bluetooth adaptor is not working in my Arch. It always worked perfectly in Manjaro, and it works in my OpenBSD, so I am pretty certain the adaptor is not faulty. Although, I believe it might be something related to the firmware, but I am not sure. The adaptor will discover discoverable devices around it, but can not establish  connection with any of them. For that reason, I bought an USB bluetooth adaptor (dongle). But, it seems impossible to use it. It is recognized by the KDE, but there isn't really a way of choosing it for system to use the dongle as a default adapter, since the system keeps insisting on using the integrated (supposedly faulty) one. If I disable the faulty device in the BIOS, I am not able to enable Bluetooth component on the KDE's panel switch at all, clicking on it nothing happens. On the other hands, in Bluetooth Devices dialog, powering off/on the default adaptor seems not to work if the integrated adaptor is enabled, I mean, I can check and uncheck "powered" on both adaptors but it doesn't do anything useful.  I am not sure if my user should be a member of the bluetooth group for that, or something; and I am not sure how to do it from the command line, properly, so I would appreciate any guidance for I really need the bluetooth facility.

If you need any additional information I failed to provide, I'll provide. Thanks!

$ lsusb (with integrated bluetooth adapter disabled)

Re: Bluetooth not working

Hey tlillenuit,

It seems like there has been a regression in the kernel. Your issue is similar to one that was already reported and even a bug has been filed.
You can check the other post here -> https://bbs.archlinux.org/viewtopic.php?id=246479

My mouse was working perfectly up to kernel 5.1.2 or maybe 5.1.1 but when I upgraded to 5.1.4 it simply does not want to connect anymore.

Re: Bluetooth not working

Thanks, I downgraded my kernel to 4.20.13-arch1-1-ARCH. There is a bit of progress shown when trying to connect using KDE Plasma's bluetooth thing, but I am still not able to pair with my speakers or my headset. I was able to pair my mobile phone device with the laptop, from the side of the mobile phone, but I can't seem to connect to any of my devices in a normal way. I can normally connect my headset to my mobile phone so I know for sure it is working. Seems like the two adapters are in collision. I have disabled the embedded BT controller in the BIOS, and have been trying to connect using my newly bought USB BT controller from the command line, it pairs finely yet it keeps failing after issuing the connect command.

UPDATE: Enabled the bluetooth embedded controller in BIOS, disconnected the USB bluetooth controller, tried connecting with bluetoothctl, it shows the controller info but can not discover any bluetooth devices around... So none of them is working.

This is my attempt to use the USB dongle as the primary controller, with the embedded one disabled in BIOS:

$ bluetoothctl

Re: Bluetooth not working

With kernel 5.1.7 my mouse is working again without any trouble. You might want to test your device again.
I deleted my mouse and went through the detection process.
I'm on KDE/Plasma

Re: Bluetooth not working

Thanks for the info I'll test it soon!
