Having a problem where bluetooth connects then immediately disconnects my keyboard and controller. keyboard is a Keychron K2 V2 and controller is a Sony Dualsense and motherboard is a gigabyte B650 Aorus Elite AX Rev 1.0. I have Bluez and all of its dependencies installed along with blueman and the issue persists. I’ve also tried disabling ertm to no avail
Manjaro newbie here
Hello and welcome to the Manjaro Community! 
It will help if you provide system information (see [HowTo] Request support) but to start with:
Enter
inxi -zv8
… in a Terminal, copy all the text, paste here;
highlight it and click the </> button at the top of the reply window to format it correctly for this Forum.
Note: The
zpart of that command filters out personally identifiable information such as MAC addresses, etc.
Please do the same for other information you will be asked for. 
Cheers!

Hi all together !
I just installed my PC with a fresh Manjaro system using KDE Plasma 6 desktop and I have the same problem with Bluetooth connecting for 1 - 2 s then it disconnects (same Hardware and Gnome desktop no issues at all … with Bluetooth).
I have a different Bluetooth chip, but also an AMD system.
In dmesg I have the following entries:
[ 8.206961] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[ 8.206964] Bluetooth: BNEP filters: protocol multicast
[ 8.206966] Bluetooth: BNEP socket layer initialized
[ 8.207400] Bluetooth: MGMT ver 1.23
[ 8.210958] NET: Registered PF_ALG protocol family
[ 8.248753] NET: Registered PF_QIPCRTR protocol family

I am no expert in Bluetooth, maybe someone has some ideas what’s wrong here?
…
Update: 
…
I let dmesg -w run an tried out activating / deactivating the USB Bluetooth device … reboot no change. Since it is an USB stick removing and reconnecting it was possible and resulted in a proper entry. Afterwards the Bluetooth connecting to a JBL speakter could be established and is running stable - as long as I don’t reboot.
regards,
Marcus
