Holographic Emulation - Cannot connect without a remote machine address specified

Hello,

I am following the tutorial “Holograms 100” from Microsoft Dev Center (HoloLens (1st gen) Basics 100 - Getting started with Unity - Mixed Reality | Microsoft Learn)

I am currently at the step where I set the holographic emulation to rendering directly on my Hololens. So I click on Window → Holographic Emulation, I select “Remote to Device” and click on Connect. When I do that, I cannot see the animation of the “Connect” button being clicked and I see an error in the logs. Here is what it says:

Cannot connect without a remote machine address specified
UnityEngine.Debug:LogError(Object)
UnityEditorInternal.VR.HolographicEmulationWindow:HandleButtonPress() (at C:/buildslave/unity/build/Editor/Mono/PerceptionRemoting/HolographicEmulation/HolographicEmulationWindow.cs:195)
UnityEditorInternal.VR.HolographicEmulationWindow:ConnectionStateGUI() (at C:/buildslave/unity/build/Editor/Mono/PerceptionRemoting/HolographicEmulation/HolographicEmulationWindow.cs:293)
UnityEditorInternal.VR.HolographicEmulationWindow:OnGUI() (at C:/buildslave/unity/build/Editor/Mono/PerceptionRemoting/HolographicEmulation/HolographicEmulationWindow.cs:353)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Needless to say, the connection does not happen.

Another thing I notice, perhaps related to the problem, is that when I click on the error message, the address text box gets emptied.

Google suggests no one else has experienced this problem.
I am using Unity 2017.2.0f3. I also tried closing and re-opening Unity to no avail.

Any help would be appreciated.

I found it is a bug for the Holographic view of Unity 2017.2
Try as following:

  1. Enter the ip such as 192.168.31.177
  2. try slide the slider of Max Bitrate a bit
  3. The ip string will still in the input box

Hope this help you!

can someone tell me what I am doing wrong with the basics of unity/vuforia/hololens?

@MaNiC Thanks for the tips!
Looks like unity 2017.2.0f3 has issues using the remote viewer. But if you upgrade to unity version 2017.2.1f1 you don’t get this issue but when you build to the hololens you get a tracking issue. I also believe the tracking issue doesn’t get fixed until the new 2018.1.0 release.
