Remoting HoloLens 2 Emulation fail by unity edit tool "Holographic Emulation"

[yuejiework]

Unity Version 2018.4.3 & 2019.1.11f1

I use Holographic Emulation try to remote my Emulation.
My connect setting like this:

But when I clicked connect button.
After 1~3 sec…
I got error mesage is : “Disconnected with error ProtocolVersionMismatch”
(And the error message looping)

I try to remote by script.
Like this example:
https://docs.unity3d.com/ScriptReference/XR.WSA.HolographicRemoting.html

It is work,
but when I connecting success, the Hololens 2 emulation’s “remoting player app” will return back home.

I guess,this example is just for Hololens 1 not 2.

So…
Can anyone tell me…
The tool Holographic Emulation connect to Hololens 2 is work?
Maybe I just miss some step??

I’ve been seeing the same problem. I think I figured it out. The Holographic Emulation window is buggy (you may have noticed you can never disconnect it once connected).

If you close the window, then reopen it (Windows->XR->Holographic Emulation), then it seems to get unstuck. You might also have to restart Unity.

What version of of the Windows MR package are you using?

Hello,
I have also an issue trying to use Holographic Emulation on Unity 2019.2.6f1 with HoloLens 2.
I have installed the Windows Mixed Reality package 3.0.6
When I try to connect Unity crashes and in Unity log file I found this error :
“attempt to access an invalid address”

I experienced the same issue.

After some workaround, my solution was to make sure I was using the same Wi-fi network as the Hololens 2 used. Any Ethernet connection between devices will disturb the connection.

Changing Scripting backend from .Net also can be a game changer.

Thought I had this problem as the disconnect button was grayed out. Then I realized that I didn’t have WSA Holographic Remoting Supported in the XR Settings. Once I enabled that I can connect and disconnect no problem.
