I have a project where a VuMark scan triggers a timeline canvas to appear in HoloLens, using Unity 2022.3.25f1, MRTK3, and Microsoft Visual Studio 2022. The Unity project is built on UWP and operates within HoloLens. Additionally, I’m utilizing a UR10e robot on a virtual machine. I need to establish a connection between the HoloLens and the UR robot. While I’ve successfully connected to the robot from Node-RED to send messages and control it, I haven’t been able to establish communication from the robot and Node-RED back to the HoloLens. Do you think Node-RED is the correct approach for this connection, and how can I integrate it with HoloLens and Unity effectively?
