Detect NReal glasses connection in separate scene

I would like users to be able to launch our app without having the glasses connected (ie: without having to go through Nebula for AR features), then have them select a button to move experience onto NReal glasses.

In separate scenes in Unity, this works for the most part. However, if the glasses are not connected, when arriving at a scene that utilizes NReal features, the app will crash. Is there a way in the previous scene (without NReal features) to gracefully detect whether or not the glasses are connected in order to prevent a crash when arriving at scenes that use NReal features?

Hi developer. Currently, our Nebula doesn’t support this kind of function. But your suggestion is good, we will take this into consideration.

The issue would be that MR features won’t work unless they are launched within Nebula
