Can people hack your iPhone Via Bluetooth if you leave it on?


I leave in an apartment complex with lots of people and often times, I would be able to see Bluetooth devices that do not belong to me on my iPhone or MacBook when I search for my Bluetooth device. Does Apple Tell you/ask by default before someone with Bluetooth devices tries to Connect to your phone via Bluetooth? Or is this A potential security Vulnerability to leave your iPhone Bluetooth on at all times? (I do since I use AirPods)

I don’t remember setting or seeing any options to set Bluetooth permission on my iphone which makes me nervous.

Thank you!
