We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.
Hololens can't scan marker on iPhone for Spectator View
I'm trying to test the shared Spectator View between Hololens and iPhone. Following the instructions, I'm able to successfully set up the project in Unity, build for both Hololens and iPhone, and run the apps on the devices. However, when it comes time for the Hololens to scan the marker on the iPhone screen, nothing happens.
The troubleshooting section said this can be avoided by creating all builds in the same Unity instance without closing the window. I just restarted Unity, created fresh, back-to-back builds for iOS and Hololens, but I'm still getting the same issue. The Hololens camera turns on and takes photos, but it doesn't scan the marker on the iPhone.
One thing to note. When generating the DLL files for the SpectatorViewPlugin, the final step is to:
Copy the following dlls from the directory MixedRealityToolkit\SpectatorViewPlugin\SpectatorViewPlugin\Release\SpectatorViewPlugin to the directory HoloToolkit\SpectatorView\Plugins\WSA\x86\
That specific path didn't exist when I brought the toolkit into Unity, so I had to create it and then add the DLLs. I'm assuming that's normal. Below of is screenshot of my Hierarchy and NetworkManager settings.
