Remote controlling of vr game

Hello everyone, newbie here.I need to control a vr app (oculus quest) from another app in a smartphone. Any ideas on how to connect the two apps?

This is the same as any other form of networked multiplayer game. Use your favorite networking framework, or write your own.

Do you have any good network frameworks in mind?

It depends entirely on your needs and background. If it’s a turn-based game (or otherwise doesn’t need to send a ton of real-time data), you might just use UnityWebRequest to connect to some PHP script running on your server. Or instead of PHP you could write the server part in Python, or Ruby, or some AWS service. If it’s a high-speed game, then I would probably use the Hazel library, because I prefer lower-level networking, but I’ve also used Photon and I know some people actually like that. Google “Unity networking” and spend some time trying a few solutions until you find something you like.
