I'm running HifiberryOS in a PI3.
# cat /etc/hifiberry.state
CURRENT_PIMODEL=3B
CURRENT_MIXER_CONTROL="DAC"

I disabled the on-board Bluetooth like this:
/boot/config.txt | grep bt
dtoverlay=pi3-disable-bt
and then connected a Bluetooth USB Dongle, which also shows up on bluetoothctl
# hcitool dev
Devices:
hci0 0A:62:30:20:4C:AE
# bluetoothctl list
Controller 0A:62:30:20:4C:AE HiFiBerry [default]
However, I'm not able to get any other device to discover the Hifiberry when scanning for available Bluetooth devices in range. It just does not show up anywhere.
bluetoothctl while clicking on the "Start Bluetooth Pairing" button:
# bluetoothctl
Agent registered
[CHG] Controller 0A:62:30:20:4C:AE Discoverable: yes
How do I debug this? To me, everything looks fine so far, and I do not have any idea on where to look next.
