I currently use CoreElec 19.5 RC2 on an Odroid N2+ and try to get my new bluetooth dongle to work.
The dongle is the UB500 from TP-Link which has the Realtek Rtl8761. This chipset is already supported and also the bluetooth stick itself is recognized by the system but can’t find any bluetooth device when i start the scan.
Here some outputs:

if i restart the bluetooth service i only get this output:

with bluetoothctl I can start the scan but it can’t find any device which is currently in pairing mode:

Any clue what can be the issue here?
I don’t know if this guide is helpful in this case: GitHub - tedboudros/tplink-ub500-linux-patch-guide: A guide on how to get the UB500 bluetooth dongle working on <5.16 linux kernels!
