First you have to add user-permission.

<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />

And then your codes, you have to check if the user is using Android 12. If yes, check the permission Bluetooth. And then you can able to use the Bluetooth.

Example here I use library from here. https://github.com/Karumi/Dexter

private void checkPermissionBluetooth() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        final ArrayList<String> listPermission = new ArrayList<>();
        listPermission.add(Manifest.permission.BLUETOOTH_CONNECT);
        listPermission.add(Manifest.permission.BLUETOOTH_SCAN);

        Dexter.withContext(Kpp02NewActivity.this).withPermissions(listPermission).withListener(new MultiplePermissionsListener() {
            @Override
            public void onPermissionsChecked(MultiplePermissionsReport multiplePermissionsReport) {
                threadBluetoothEnable();
            }

            @Override
            public void onPermissionRationaleShouldBeShown(List<PermissionRequest> list, PermissionToken permissionToken) {

            }
        }).check();
    } else {
        threadBluetoothEnable();
    }
}

Manifest.permission.BLUETOOTH_CONNECT, Manifest.permission.BLUETOOTH_SCAN permissions are granted — ashim saini, Apr 01 '22 at 07:37
@ashimsaini have you checked the permissions at runtime as suggested by Ticheraz? — Michael Kotzjan, Apr 01 '22 at 08:22
@ashimsaini I am facing a similar issue with Vivo devices, did you find any solution? — nikk, Apr 08 '22 at 05:15
I could make it work by adding android.permission.BLUETOOTH permission runtime — nikk, May 06 '22 at 15:57
