Depends on the device, there was a story recently of a Nissan infotainment system that was perma-pairing as long as you had the options screen open afaik. If your earbuds are pairing close by, as is the machine - you can probably make some rudimentary motion tracking. Gonna be inaccurate as hell though, and it relies on both devices permanently being in pairing mode.
I can get a lot further from my phone than I’d be from the drink machine in who knows how many fast food spots before service drops.
This part though is way easier to explain with interference. A typical fast food restaurant has dozens, if not hundreds of wifi and bt devices. Nothing surprising when your phone has to fight to get loud enough for your buds.
But you have to accept the pairing in the first place. Bluetooth doesn’t work without a handshake between devices. If you never use the Bluetooth feature in their app, you don’t have to worry about it. Also apparently these machines have been out since 2018…
You don’t have to accept pairing, if both devices are discoverable they can see each other. It doesn’t have to be some app, you can be discoverable with 0 apps installed. That’s what I’m talking about with rudimentary tracking.
edit: pairing mode = discoverable, accepting pairing is not required, and obv the machine has to be perma discoverable for “tracking” to work
