I did some investigation and it seems that in the latest deovr update (steam v15.1) the script support for Haptics Connect is purposefully disabled, DeoVR now only sends move commands directly to BLE devices. So even if MFP connects to Haptics Connect, the script wont work.
Will have to see if this is their long term plan, if it is they will probably remove script downloads from sexlikereal in the future and transition to an api similar to The Handy. I’m assuming this is in preparation for their own device release.
Solution for now is to use v14 as long as you can or downgrade from v15.
I’ll see if I can update MFP to still work with v15 or later.
