FILCO Majestouch Convertible 2 (bluetooth) keyboard can work after paired.
After disconnect or OS reboot, the keyboard cannot be connected.
Found some "Connection refused - security block" and "Error: Remote User Terminated Connection" in hcidump.

This keyboard can work (connect and disconnect) with early Tumbleweed version, before May 13th.

The following is output of "bluetoothctl" command:
[bluetooth]# version 
Version 5.50

Comment 1 Dawei Pang 2019-05-27 09:47:30 UTC 
Move to kernel, because I replace bluez to Leap15.1, this issue is not fixed, replace kernel to Leap15.1, this issue is fixed.

Thanks,
Dawei
Comment 2 Takashi Iwai 2019-05-27 09:59:59 UTC 
Please check the kernel in OBS home:tiwai:bsc1135556-2-15.1 repo,
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1135556-2-15.1/standard/

That contains some recent fixes that might be relevant.

Thanks Takashi!

The following is my recent result:

kernel-default-5.1.4-1.1.x86_64  -> Hit this issue

kernel-vanilla-5.1.4-1.1.x86_64  -> Hit this issue

kernel-default-4.12.14-lp151.1.1.g5b96dc0.x86_64 -> NOT hit this issue (Fail to start X, try to connect bluetooth device in text mode)

kernel-default-4.12.14-lp151.27.3.x86_64 -> NOT hit this issue (Leap 15.1)

So I think the bluetooth connection issue is caused by upstream, will try to compile the recent upstream kernel to identify the version imported this issue.

Thanks,
Dawei
Comment 4 Takashi Iwai 2019-05-27 11:58:50 UTC 
Ah, sorry, you're using TW, not Leap 15.1.
Then please test the kernel in OBS Kernel:stable repo.  The recent fix I mentioned is already included.
  http://download.opensuse.org/repositories/Kernel:/stable/standard/

Thank you, yes, this issue is fixed on kernel: 5.1.5-2.g6ad4f79-default, is dup of bsc#1135556.

Feel free to correct me if anything is wrong.
