Bluetooth problem doesn't reconnect

Hello my friends
I'm on manjaro kde since last summer
and my problem is that a couple of days i boot up my laptop and the Bluetooth mouse doesn't connect automatically , but only if i delete it from the paired devices and pair again. My BT mouse is a noname mouse from ebay and it works pretty good before manjaro kde on mint kde too. I tried another bt mouse and i have the same result.The laptop is dual boot with win 10, on win 10 works good.So i thing it is some driver where the problem is.My laptop is a dell xps-l502x i7 8gb and here are :

Μαΐ 23 12:15:28 beams bluetoothd[696]: Can't get HIDP connection info

is there someone who can help me??
Thanks a lot

Try installing and testing the real time kernels. A few people have said they worked better for this issue. Install kernels through Manjaro Settings Manager, and always have at least two kernels installed at all times for safety.

How to switch kernels:

When you reboot if you do not see the grub boot screen press and hold down the ESC, SHIFT or F8 key. This should show the GRUB boot menu if it doesn't appear. As soon as you see the grub boot screen, press the down arrow. Select the "advanced" menu from the choices and press enter. In the next menu you can select the different kernels you have installed to boot from. Select the regular kernel you wish boot into (not the fallback), and then press enter to complete the kernel change.

hello tbg
and thank you very much i try it and it works.
i have now another question is there any problem to work with rt-kernel so that i remove the latest kernel?
so that it boots automatically in the rt kernel
thanks a lot again

You should always have at least 2 kernels installed for safety in case the RT kernel gives you problems (and at least one of those should be an LTS kernel).

You will be able to boot to the RT kernel automatically if you uninstall any kernels newer than it. Be sure to install a backup kernel such as 4.14 and test it out first before uninstalling any kernels.

Please mark your thread solved by applying the check mark below the post that gave you a solution.

(edit) please don't mark hour own post as the solution when someone else gave you the suggestion on how to fix your issue.

thank you for your advice
i will keep this in mind
have a nice day

Here is another method you can use:

I've had the same problem. Switching to a realtime kernel has solved it, thank you. May I ask why a realtime kernel is required? I've tried a couple of Ubuntu distributions with generic kernels, and my bluetooth hardware works just fine with those.

You'd probably have to ask a kernel developer to get an informed answer to that question.
