I can confirm that both rotational and positional tracking with Nolo VR finally works and does it really well! There is still slight rotational drifting issue when tracker can randomly start rotating from initial orientation. It happens very randomly – sometimes after 20 seconds and sometimes after 20 minutes. Currently in VRChat I fix this by changing avatar and recalibrating. Probably this is just Nolo issue but would be cool if there is a way to reset orientation of trackers to initial by pressing some key combination on controllers.
