Cannot connect to Direct Preview

[aiddun]

I'm using UE4 using a patched version of the SDK (see my previous post), but what I did may be helpful here. In running adb shell cat /sdcard/DirectPreview/config.json, I noticed that the ip it spat out in the json file wasn't at all the IP of my computer, and reinstalling the APK didn't fix it. I manually edited the ip to my PC's LAN correct ip (using a plugin in VSCode) and now everything works from basic testing. I think this might have been because I have a bunch of different (virtual) network adapters on my PC.

Hi, aiddun.

When I also ran adb shell cat /sdcard/DirectPreview/config.json, the IP was different from the PC.
How did you change the IP in config.json?
I also use VScode.

Hello, I am working in Unity 2020.3.11f1 using WaveXR SDK 4.1.1 to develop and app for the Vive Focus 3

I am having trouble setting up the Direct Preview feature, I have a working build of my application on the headset but no great way to debug it. I have followed the guide here, https://hub.vive.com/storage/docs/en-us/UnityXR/UnityXRDirectPreview.html, with but after I start the device APK I will just end up with a connection time out every time.



I am using this to get the device IP, I have also made a script in unity using Dns.GetHostEntry(Dns.GetHostName()).AddressList to print the IP of the device in the headset, this returned 192.168.1.145

These are the settings for Direct Preview in the editor

And this is the output when starting the server, it does not change when I launch the device APK

Any help would be greatly appreciated!

Hello there,

Exact same problem happening here, and I could not find a way to use VBS in order to use the Play mode in Unity.

Is there any news ?

Hi @Dario and @Alex_HTC,

DirectPreview does not work.

Neither in USB nor WiFi mode. The connection just times out. What is your setup to make this work ?

Also, care to explain how to use VBS ? Because it only shows the basic SteamVR layout in the headset, but does nothing when Unity enters Play Mode.

 

Thank you.

Hi HTC!! 

 

I am having the same issue as all above users, is there a working solution as of today for this ?
