All the discovered devices can be fetched with https://developers.home-assistant.io/docs/core/bluetooth/api?_highlight=bluetoot#fetching-all-discovered-devices

bleak is likely going to be doing a scan for LE devices only so you likely won't see any BR/EDR devices which is what I believe this integration wants. Unless I've missed something, it seems this PR fixes the bluetooth_tracker integration by making it discover LE devices instead of BR/EDR devices.
