This post to help anybody that would like to debug/work on GearVR or other mobile devices over WiFi.  There is a pull request that was approved today.  The code to implement was literally 10 minutes of mostly copy/paste, while the setup took over an hour to figure out, so I wanted to share that (also for my forgetful self in the future!). What does work on GearVR is trigger button will select meshes.  Trackpad allows you to rotate.  At least with trigger button working it is somewhat usable
