This isn't to the level of the OP, but I just asked Claude "Are there any interesting Bluetooth devices in my vicinity which aren't actually mine or ones I am connected to?" and it downloaded a tool called `blueutil` and identified a variety of things.

When I complained that the results were boring, it installed a Python package called 'bleak', found a set of LED lights (which I assumed are my daughter's) and tried to control them. It said the signal was too weak and got me to move around the house, whereupon it connected to them, figured out the protocol, and actually changed the lights while I was sat on her bed - where I am right now. Now I have a new party trick when she gets home! I had no idea they were Bluetooth controlled, nor clearly without any security at all.
