dko777 I don't know about this app at all, so everything below is a pure guess. With that said, the app may want 'nearby devices' permission. If it doesn't have it in its permissions list, then maybe it wants Play Services with 'nearby devices' permission granted.
If you don't have Play Services installed currently and willing to try it, it's possible you'll need to reinstall your app after Play Services installation and opening it once.
