[SOLVED] Bluetooth not working

Hello, I have just installed arch and my bluetooth is not working (my desktop environment: gnome) . Every time I try to connect something using bluetooth it connects and disconnects immediately. I have tried that on ubuntu by a live usb to make sure its not my device's fault and it worked on ubuntu. Now what should I do?

Edit: I tried with bluetoothctl, here is the log:

Re: [SOLVED] Bluetooth not working

I had the same problem. I installed bluez-git from the AUR and removed /var/lib/bluetooth. It is working after that.
You can downgrade bluez too instead of installing the bluez-git package.

That worked. But will pacman change it back to the latest version if I run a full system upgrade? (I am not sure, I am new to arch)

Re: [SOLVED] Bluetooth not working

Yeah it'll will be updated along with a system update. You can use the git package. pacman doesn't update AUR packages.
