Hey Endeavour.
Once again I’m calling for help with keyb related issues. I’m trying to connect my keyboard to my PC running KDE Plasma and EndeavourOS. I’ve made sure I’ve got packages mentioned on Arch Wiki such as Bluez and bluez-utils. Tried to connect with bluetoothctl and KDE bluedevil.
Bluetooth confirmed working with a PS3 controller. Keyboard confirmed working with my laptop.
Anyone got any ideas what I could be forgetting?
sudo bluetoothctl
power on
default-agent
pairable on
scan on
pair XX:XX:XX:XX:XX
trust XX:XX:XX:XX:XX
connect XX:XX:XX:XX:XX
replce XX:XX:XX:XX:XX with the UUD of the keyboard will be shown on scan (out keyboard in pairing mode before)
Tried this already, no devices (apart from myself I’m guessing) shows up 
could be hardware incompatible… i also would not recommend BT input devices at all 
Better use RF ones…
And tried bluetoothctl as root or normal user?
Both!
I have a trusty good ol’ cable, but my desk-ocd would love some wireless bluetooth keyb (also my lazy self when I put my chair back)
Is there a clever way to check whether my bluetooth is faulty somehow? systemctl status bluetooth throws this:

Hmm hilariously enough I’ve so far been able to connect my phone to my PC, my phone to my keyb. I’m going to have a look in BIOS to see if I can get smarter that way :d
can you give hardware info on the two BT devices?

My mobo is a Z490 Aorus Pro AX
and BT is integrated into wifichipset? as i do not see BT device
Hello again Joe Kamprad
I figured out the issue. It was infact a shared wifi / bluetooth card. It turns out bluetooth is very temperalmental unless you plug in the arial into the wificard - so seems everything works now!
Whats funny is both my phone, my playstation controller and my laptop all connected fine. Oh well, tech I don’t understand I guess heh.
because of something like that i do ask for it 
I’m back now again with more stupid questions.
I updated and rebooted my PC, and now bluetoothctl throws a ‘yes no’

[CHG] Device DC:2C:26:DC:93:D8 Connected: no

[CHG] Device DC:2C:26:DC:93:D8 Connected: yes
[CHG] Device DC:2C:26:DC:93:D8 Connected: no
… and so on. I tried to pair, which gave me an expected failed to pair: org.bluez.Error.AlreadyExists. I then tried to connect, which threw a 'Failed to connect: org.bluez.Error.Failed.
The connected: yes, connected: no has been rolling in my terminal for a little while now. Any ideas what I could do?
I tried to remove DC:2C:26:DC:93:D8, then pair it again, which throws a quick connected: yes, before a Failed to pair: org.bluez.Error.AuthenticationRejected, before a connected: no.
And a new output! I did connect once again, and it threw me a:

Try install bluez-hid2hci with pacman
I tried it, bluetoothctl still spamming ‘yes no’ - my keyb doesn’t use a usb bluetooth dongle tingy though. Nothing is plugged into my PC (except for my native bluetooth chip heh)
by any chance you where dualbooting?

I actually am, but I haven’t booted up my windows install since this friday - way before I got my keyboard working
