Hello, I am having the same problem on HTC Focus 3
It doesn't work at all on wifi. Followed the procedures of the official documentation countless times, no error, everything works, the server is on, helmet is detected... But static image on the helmet...
After multiple hours of test, I managed to make it work with a very non-practicle hybrid method :
I set up the settings for the wifi, then switch to the usb panel and launch the stream app, then the apk. I have an image on the unity editor but not on the helmet (thanks usb), so it is not really usable.
It is very tiresome to build our apks again and again, could you please make a tutorial that goes from A to Z, one time, to have the directpreview working on wifi ?
It will save us so much time.
Thanks in advance.
