Automatically enable / disable Bluetooth to scan devices

[Sweazou]

As I know, if the Bluetooth isn't enable, the app won't scan for devices, it'd be nice that the app automatically enable Bluetooth to scan devices if it isn't on and then turn it off after if it was off.
Idk maybe I'm crazy because nobody is talking about it.

What would be the advantage of turning bluetooth off? Energy savings?

It'd but in my case my Bluetooth is always off when I'm not using it

[ASerbinski]

Yes, but why don't you leave it switched on? What is the use case for switching it off when not in use?

Security issues

[ASerbinski]

Well this is an Android application, so it runs on an Android phone, which unlike those made by the fruit company, does NOT continually spew bluetooth beacons for the whole world to track. I think you might be overestimating the security risk associated with keeping bluetooth turned on.

I'm talking as an attacker

There's an API which would allow the app to turn on Bluetooth, but the documentation states that it should only be used to enable Bluetooth on purpose. So we could not use that for background scanning.

Might be an option to put a setting in the app: activate Bluetooth when doing background scanning.

Android 13 does no longer allow to activate / deactivate Bluetooth automaticaly. We added a detection if Bluetooth is disabled and will show a button to open the settings when using the manual scan
