Works fine here. Do you see the permission dialog? Check whether location services are disabled on your device. It might be related.

Yes the dialog box with the request for authorization appears (obviously only the first time).
Location services are active but it doesn't work the same.

For now I have solved. Even if it is an Android 10 phone, targetSdkVersion <= 28 must be set.

Sorry to reply on an old thread, but FYI i am experiencing the same problem on my Xiaomi Redmi Note8T, since the update to MIUI 12 (which carries android 10).
Only way to get bluetooth to work was to set SDK Version to 28, so it seems it's not a problem on samsung phones only

possible. I'm running the app outside GooglePlayStore, so it wasnt a big issue for me. But for the future i hope someone has a solution.
For Erel: i'm using the latest update BT as shown in the examples.
Unfortunally i cannot check it, i dont own such a phone

You should never post in old threads. Always start your own thread.
