Bluetooth management interface is not activated, why?

I don’t think this will solve your problem.

If you don’t have the bluez packages in your cache try the Arch Linux Archive (ALA). You can install downgrade to ease the search.

So, i’ve applied

sudo DOWNGRADE_FROM_ALA=1 downgrade bluez

and selected version 5.61.1.

This is the first time I use downgrade and I am still unsure about dependencies, but everything seems ok.

Blueberry does no longer work. Anyway I have usedbluetoothctl and I am now connected to my headset.

But it’s still impossible to get connected to my keyboard.

connect 2B:24:13:DB:7C:99
Attempting to connect to 2B:24:13:DB:7C:99
Failed to connect: org.bluez.Error.Failed Input/output

I also downgrades bluez-utils and bluez-libs to the same version.
