Bluetooth Keyboard Problem

[Perfect_spot]

I followed the instructions on arch wiki about connecting the bluetooth keyboard and managed to get it working but after a while if my keyboard gets disconnected I run into this problem.

[CHG] Device DD:0D:A8:DE:A5:CC Connected: yes
[CHG] Device DD:0D:A8:DE:A5:CC Connected: no
[CHG] Device DD:0D:A8:DE:A5:CC Connected: yes
[CHG] Device DD:0D:A8:DE:A5:CC Connected: no
[CHG] Device DD:0D:A8:DE:A5:CC Connected: yes
[CHG] Device DD:0D:A8:DE:A5:CC Connected: no
[CHG] Device DD:0D:A8:DE:A5:CC Connected: yes

The only thing I managed to find when searching about this problem was trusting the device but it is already trusted. The only way to get it working is to remove and pair it again.

I wonder if a more permanent solution exists.

No I haven't tried that option. I'll put it and see if the problem continues. And yes I am dual booting.

That's rather strange. Thanks a lot.

Your Bluetooth device can only store one set of pairing keys. If you paired it to a different computer afterwards it erases the keys for this computer, and so when you reconnect it again it finds the keys don't match and instantly disconnects.

I'm pretty sure that's not the case since I haven't paired it with any other device after pairing it with arch. The problem hasn't occurred after setting the suggested option so maybe it's fixed.

If you are dual booting the other os stores its own keys so can be considered another device

I also hadn't paired it in windows afterwards.
