It really looks like a dark art that no one wants to share the resolution too.
I too am facing the same situation… Hitting my head against a bed of nails on this one.
I’ve reset the tracker back to default settings… Tried changing the Tracker Puk to different settings. Nothing, the tracker always points up in the X Axis where it should point up in the Z.
The videos of just connecting the Vive tracker to a camera and setting up the simple blueprint all looks great but need an explaination of the befores of how the Tracker is setup before the blueprint or some thing.
Please help…anyone
