How can I find the software/service that is reading from the Bluetooth device

I have a VM that’s using my Intel NUC Bluetooth. But I don’t remember how I set this VM up. If it weren’t for the fact that I know a program is getting information from /opt/bluetooth/c0:B6:F9:8D:A6:75 I wouldn’t know that Bluetooth was even working in the first place.
