How to send UDP-Packages to HoloLens2 via USB

edited February 2020 in Q&A and Discussions

Hello community,

at the moment I work on a Unity-Application (UWP-Build, unity 2019.3) which should receive UDP-Packages and process them. Therefore I created a UDP-Communicator which uses Windows.Networking to set up the connection. Now I might be done, but at the moment I am not able to test the functionality in a real network, so I have to send the packages from my developement-computer to the HoloLens 2 device via USB-C cable.

My question is, how I can send this packages to the glasses. I already have a test Tool which sends UDP-Packages and was approved in another project, but I am not able to send the data to the glasses via USB-C cable Connection. Since in Device-Manager you can also stream a live-preview from HoloLens to the computer, it might be also possible to stream data the other way round, but so far I was not successful in doing so. Can anyone help me in this issue?

Tanks in advance

Johannes

    Simply check the IP-configuration in Device Portal, there you will find "UsbNcm Function" with an IP-address, if you send Data to this address HoloLens receives it.

  • I already tried to send data to LocalHost and also switched the corresponding ports but it didn´t work, that might be interesting in advance.

  • Dear Johannes,
    I m trying to establish a connection btw pc and hololens too, but using wifi. You said that you were unable to test it in a real network and I m having trouble too. Why you were not able? If you want to share we can try to solve it together!
