This is expected behaviour. Android requires GPS for BLE discovery. This is true not only for Qt app, but for all Android apps.

Android SDK 30@RSmirnov its no bug, its a stipulation from the OS due to security
You can potentially derive the physical location of a device when using Bluetooth without the User being aware of that. For that reason you have to enable GPS/Location service to use Bluetooth, that way the user is aware of that

If I recall correctly, GPS is not needed for BT classic.
It turns out that to scan devices, I will force the user to turn on GPS every time and it will be ok?
You don't need to force anything. Get the Android permission and system will do it automatically for you.

@sierdzio Ok, I will understand why I do not observe such (system will do it automatically) behavior. Thanks!
@RSmirnov if your issue is solved, please don't forget to mark your post as such! Thanks
