Recalbox 9.1 no bluetooth devices

[SilverGreen93]

Hi,
I am trying to pair a Bluetooth Keyboard (Logitech K380) to my Raspberry pi 4 Recalbox.
I go to the Pair a bluetooth controller menu, scan for controllers, but it always says NO DEVICES.
It does not detect any bluetooth device (yes, my keyboard is in pairing mode and it works with Raspberry pi os on the same device).
Is this a bug?

Thanks,
Mihai
