How to access files on external server from application deployed on Hololens2.

Unity Engine

I’m looking for a way to access files on an external server from an application deployed on Hololens2.

I am trying to get the sequence data referenced in the application from the file saved in the external PC with a script.
But it doesn’t work.

I can get the data from the file in Hololens2, but I cannot access the file on the external device.

Also when running the application on a PC [windows10], I can access the file on the external server with the same file path.

I’ve spent a lot of time researching, but I haven’t found any examples that could help.

Is it currently impossible for Hololens to access files on external devices?

Please let me know if you know anything about this issue.

Thank you.

Hi Tomato,

I don’t know if you’re still stuck in this situation but in case you do I’m going to answer.

Did you check all the network capabilities on the Unity Player settings (Publishing Settings) ?
Also, you can try to disable your firewall on the external server if there is one.

Keep me in touch,

Hi Kent,

Thank you for your reply.

Yes, I checked unity’s publishing setting. I also tried disabling the server-side firewall.

We contacted a Microsoft employee to ask them for their technician’s views.

“It’s due to SMB capability of HoloLens. From my view, it hasn’t been supported.It seems a common issue/request and engineering team is now working on a solution.But they didn’t provide accurate schedule.”

So, at the moment, it seems that Hololens cannot access external files by specifying the path of the external PC.
I look forward to future improvements.

Hey,

So, did you find a solution ?
I m use to access to my server files by windows IIS from the HoloLens and it works fine.

Hi Kent,

Thank you for the good information.
But for my project, I have a large number of Hololens in mind, so the problem is the limit on the number of devices that can connect to Windows Iss. It is very disappointing.

As a result of various studies, we are studying how to make a page that uses images and files that we were trying to express with Canvas of Unity into a web page on an external server and access that page with Hololens.

Thank you.
