Using the Base Station 2.o and VIVE Trackers without a headset

Recommended Posts

Hello! I am currently trying to use two VIVE 2.0 base stations along with the VIVE trackers. Does anyone know if it is possible to run SteamVR without a headset? (I do not own a headset, so I am trying not to use it even in the setup process). If so, does anyone have any tutorials/resources for this setup process? Ultimately, I am trying to track objects in the real world and import their location into Unity, so that moving a tracker will affect the virtual object's location in real time. Is a headset required for this process? 

Any help would be much appreciated!! Thank you!

Hi @rheamw ,

You can use what's called a null HMD driver. Triad (the company Valve contracts to make the SteamVR sensors) recently released an updated guide to the workflow you need to use within the last week - I haven't been able to test out their new recommended flow. In any case, the null driver is the way to achieve this - I'm not super sure about the python stuffs.

Please keep in mind:

  • Each one of the trackers will require you to have a corresponding Vive tracker dongle for RF
  • The 2.0 basestations are only compatible with Vive Tracker 2018 which are easily ID'd by the blue Vive logo/power button. The first gens have a grey logo and won't work with 2.0 tracking.

@VibrantNebula One other question -- do you know if the link box is required to be able to use the base stations?

@rheamw - Good question. You should only need the linkbox if you want to control or configure the basestations or use bluetooth power management. I'm honestly not sure how this would work with SteamVR 2.0 tracking because the units may by default ship all on channel 1. On the back of the 2.0 stations, there's a pinhole which you can use a paperclip to manually change the channel if there are conflicts. I believe that manual channel change button still works but I can't confirm it as I'm currently remote working and only have 1.0 stations. You'd probably also have to plug the stations in via USB to update them - this may be required to get everything on the same SteamVR version so tracking works.

Just remember - moving around a basestation while it's spinning will damage it so be extra careful if you try to plug it in via USB or change the channel. Have a plan and minimize the shock you apply to the station.

@rheamw - I just unboxed two basestation 2.0's and can confirm they ship by default in channel 1 and that you either need to use the pinhole in the back or SteamVR's channel management GUI to get them on separate channels otherwise they'll conflict and your tracking will be broken.
