Bluetooth privacy and use case discussion

I recently got blueman working in my sys-usb vm. I am wondering if it has bluetooth device address randomization by default.

Interested in understanding any use cases for bluetooth other than usb mice, keyboard, headphones etc. I tried to send files to my android with no luck lol. There is also a hotspot over bluetooth option in android. Curious to know if anyone would recommend that over wifi hotspot (for privsec/opsec reasons).

I also am trying to figure out how to pass-through my bluetooth heaphones to my android-x86 vm. If anyone has had any success here, this would be awesome. Unfortunately, my heaphones manufacture requires network access to configure the heaphones - so dumb. I even tried using the app with wifi on but network access off in GOS settings but no success hereā€¦
