Blueman constantly reconnects Keychron K5 keyboard

[xtroce]

When I tried to setup my keychron K5 bluetooth connection via blueman,
the keyboard constantlky reconnected after connecting the keyboard (actually it disconnected and reconnected with every keypress). I could also see the same in the bluetoothctl console.

Removed, disconnected and tried again several times, always with the same result.

I finally fixed it by removing and distrusting the keyboard in the blueman applet and setting up the entire keyboard via bluetoothctl. Now it works without a hitch.

Multiple other people had the same problem, but i could not find a bugreport here so i thought, i'll shoot one in.
you can find the comment that brought me to the right solution here: https://bbs.archlinux.org/viewtopic.php?id=248693

If any extra info is needed, im glad to provide it. I think i can replay the issue by disconnecting again (probably will pop up next reboot)

my versions:
System Arch

Blueman

extra/blueman 2.4.1-2 (1.3 MiB 5.0 MiB) (Installed)

UPDATE: It seems the blueman applet was doing something weird, after remove the device and pair it again using the CLI, now the keyboard reconnects immediately without any issue. What I did:

$ bluetoothctl
power off
power on
scan on
# press fn+[1,2,3] for 4 secs and wait until appears the K2 device
scan off
pair DC:2C:26:2C:EE:46
trust DC:2C:26:2C:EE:46
connect DC:2C:26:2C:EE:46
