PetrK79 Hi Petr, I had the same problem and issue.
I can tell you what I did to make it work.
First, I am using Oculus Quest. Have the app SLR installed there.
On my phone I have the interactive app installed.
I also downloaded a script from realtouch, and downloaded a video for the script from the respected studio site.
The script file and video file I named to be the same and put them in their own folder on my Quest.
From there, I turned wifi/bluetooth on my phone, then turned on my launch. Hit scan, and was able to connect it to the interactive app.
Logged in on my Quest to the SLR app, and then was able to pair SLR to the interactive app. (SLR Connection had a green check mark)
What was confusing to me was that I didn't know if the launch was connected, but I guess when the 'launch' is highlighted green, it means that it is connected. The blue light on my launch was also solid and not blinking when it was paired.
Long story short, what made it work was to name both the script file, and media file the same, and then put them in a brand new folder with nothing else inside there. I need to play around since it seems that there is a few second delay with the movement, unless it was just the script file I have.
Hope it works!
