Android has a feature called "nearby device scanning" so even if you turn off bluetooth, apps can still do BLE. I suspect stuff like this, where many many apps can spy on you on behalf of others, is why Google made BT access a Location category. But it means your weather app that uses location to tell you where you are? It is selling your location via BT beacons to 3rd parties.
For those who are interested, this feature can be deactivated. The location in settings has moved around a bit, but you can just search for "nearby device scanning" and shut it off for both Wi-Fi and Bluetooth.
Meet the newest Android Q (10) which is available as a beta. The permission levels are there for what you wish. It's impressive to see just how many apps were previously getting background location (and many other) permissions by default. Eye opening experience for someone that figured it wasn't that bad.

I would like to congratulate Google for such hard work. I mean, CyanogenMod 7 in 2010 could revoke any app permission at the user's will, but you know, computers are difficult
