Prompt to enable Bluetooth when it is disabled

[AtmosphericIgnition]

Description

I do not use any Bluetooth devices on a regular basis, but I do scan for Bluetooth beacons through NeoStumbler. When I forget to turn on Bluetooth, and start scanning with NeoStumbler, it just collects data without the Bluetooth beacons. I know that an Android app can ask the user to enable Bluetooth when it is disabled through the this prompt:

Suggested implementation

When the user starts scanning without Bluetooth enabled on their device, they should be prompted to enable it.

I'm thinking about UX for this

• If you don't want to scan Bluetooth beacons for some reason and don't enable Bluetooth, should it prompt to enable Bluetooth the next time you start scanning?
• If you start scanning from the quick settings tile, would it be better to open the UI for the prompt or to just start scanning without Bluetooth?

As a workaround, see if you can enable Bluetooth scanning to be always available in your device settings:

I have both enabled, but it seems that NeoStumbler won't scan for BT beacons with Bluetooth disabled, and this setting enabled.
