Recently bought my second vive and i tried to extent my play area with the base statioins from the second vive, so i tried to connect four of them. First i tried to go with bluetooth for two of them, the others on cable.I tried so many different chanell combinations for each pair of basestations.Also i put each pair on cable connection.
After alot of tinkering steamvr recognize all of them in green anyways the connection was unstable, they goes random from grey to green in steamvr tab.I tried to run room setup, but the headset is not recognized no matter where i'am in the player area.Also i update firmware for all basestations.
So my question is it possible to play Vive on 3 or more basestations ? If yes how i could do that ?
Have a nice day !

No, two base stations are the max. However, you can link more than one headset to the same two base stations and play in the same play space at the same time. More than two base stations is unnecessary for that purpose.

thanks so much for the quick reply.
We are planning to use it for a educational purpose.
The project for which we hope we can use more than two lighthouses (so we can have a single player with a backpack PC walking around the real dimensions and not teleport at all) is aimed for training mainly students.
We are currently Sony partners and Enterprise EPIC users and we mostly need dev solutions.
We already saw that steamVR can detect multiple lighthouse couples, but as I mentioned it simply gets unstable.
If there is a inhouse version of the software which allows having a larger play area (larger than the 5m diagonal) is there a way for us to apply for it so that we can test a real size factory dimesion.
What we basically aim for - functionality wise - is more or less the same walking capabilities as seen on this Ghostbusters experience https://youtu.be/_QIbI4Wtgug
Please let me know if you think we might have some kind of a solution to the multiple lighthouses
I'd happily discuss the project in greater detail on a less public forum because all the NDAs we are currently under.

what you're aiming for will not be possible with the current-generation Vive (7m diagonal with synch cable is the maximum that was still stable for us). However, that is something that is currently in the works with SteamVR 2.0 tracking, which will require new hardware.
The new Lighthouse base stations are scheduled to go into mass manufacturing next month. They will feature a laser that will carry information about the base station ID that the laser is coming from. In combination with the newly developed ASICs, sensors on the devices will be able to distinguish multiple base stations that way, which means that compatible devices could theoretically be used in the following ways:
Right now, there is no official schedule on the delivery of any new HMDs or controllers that carry the new ASICs. Furthermore, HTC is currently still in the experimentation phase to find a solid way to implement the functionality in the firmware. Thus, no schedule yet. Right now, for anything that exceeds the above measurements, the best stable solution would be OptiTrack, which comes with massive hardware costs, however.

This isn't a software limitation of the current SteamVR tracking iterations, it's a hardware limitation. In short, the current system is based on measuring the timing of "flashes" and "sweeps" emitted by the lighthouse. The "flash" is the bottleneck for both size of the tracked volume as well as the number of lighthouses that can concurrently be employed. Steamtracker 2.0 technology will encode information in the sweep that will eliminate the need for a flash and enable daisychaining but the technology isn't consumer available yet. For a detailed breakdown of how lighthouse technology works see this talk by Alan Yates.
In the interim, you can use two lighthouses connected via sync cable to extend the range of the lighthouses for staging and development purposes. Note that when you do this, occlusion and coverage become increasingly important to keep in mind. You can also go with IR tracked systems like Optitrack but expect to pay at least $100K USD for a moderate sized tracked volume. Partially why Steamtracker 2.0 is so exciting is that it will reduce the price for larger tracked volumes by at least 100 fold and make warehouses scale volumes very easy and affordable to track.
Feel free to PM me if you have futher questions.

Could you tell me which games can be used with two HMDs at the same time? I have both and would love to use them this way. Thank you very much.

Any Vive supported VR game with more than 1 player would allow you to play with multiple players. It doesn't matter where Vive is phyiscally located because it all happens over the network/internet.

Yes, if you are using original Vives with the 2 base stations, 2 computers, you can have 2 vives with controllers in the same area, just map out play area for each vive within the base station area so you don't run into one another, I've played this way many times with my son.

I tryed to use 2 Htc Vive headset with 2 base station 1.0 but the result was completly unstable and I was not able to play, probably because the distance between the 2 base station was also at the limit of the 5 meters allowed.
I was wonderind, would it be possible to use 2 base station 1.0 on 2 corners and 2 base station 2.0 on the other 2 corners. On the area I would be using 1 headset htc vive + q headset htc vive Pro.
Would all this be possible and working well?
Thanks for your answer.

You cannot use more than two v1.0 basestations in the same area at the same time due to how their sync system works. Because of this sync system you can also not hybridize 1.0 and 2.0 basestations in the same area - you need to use one or the other and due to the radius of the sync array's flash, if you use a 1.0 setup, you have to physically isolate the tracked volumes.
I've attached a compatibility chart below that shows the cross-compatibility. Basically, if you want to use a Vive and a Vive Pro in the same tracked volume (aka "co-location") you'll have to use 1.0 basestations to drive both HMDs and you'll be limited to the 5m range posed by those HMDs. You can use 2.0 as it will be invisible to the original Vive and you can't hybridize the systems because the 1.0's sync flash will interfere with 2.0 tracking.
When troubleshooting poor tracking - the primary culprit is typically reflections. Scan your area for reflections and potentially try using the sync cable (with the basestations set to A and B) to see if that mitigates your problems.
If you want to learn how lighthouse tracking works - this is the most informative video on the matter.

I wanted to give it a try and I just recived the new Vive pro complete set.
Following your hints I just installed a Htc Vive 1 gen side to side to the new Vive pro:
2 areas 2 base station each in an open space room.
I found out base station 2.0 were not disturbed at all by 1st gen bases.
On the other side instead I wasn't able to use the first gen headset because of interference
of the newly purchased Base 2.0.
So from my direct experience base stations 2.0 are visible to base station 1.0.

Well, at the end It looks like I managed to set up in one room 1 Htc Vive 1 gen with usual configuration and the new Htc Vive Pro with both base station on one side with their back to the other headset.
So far both configurations work pretty well with no interference, so basically BASE SATATION 2.0 did the job!
With this configuration I can say the new headset was really worthing the upgrade!!!

I am hoping we can connect with you as we are about to package up and send out 6 HTC Vive Pro stations back! We are also in an edcuational envoronment and having challenges with getting our 6 stations to run consistently. We are in the Bay Area of California; where are you located? We are using Omen X laptops and the technical difficulties abound. Our on site technician can't get any phone support and trying to text about a lab environment is painful. Any ieas? Wondering how you set your lab up?
