HoloLens 1: Gestures not recognized in Unity 2019.4 with MRTK 2.8.3

[sergiocicconiunitnit]

I own an HoloLens 1 and so far I have developed some AR projects with Unity 2018.4.23f1 using the HoloToolkit (the version available in 2018). Now I want to develop a new project for HoloLens 1 with Unity 2019.440f1 LTS and use MRTK 2.8. I also use Visual Studio 2017.
I created a new project and followed Microsoft's instructions on how to install and configure MRTK 2.8.3 (for example, I followed Microsoft manual "Set up a mixed reality project in Unity with the Mixed Reality Toolkit"). I added the MixedRealityToolkit to the new scene I created. For the MRTK Profile configuration, I selected the DefaultHololens1ConfigurationProfile. In the Input section, I activated the InputSystem and selected the DefaultHoloLens1InputSystemProfile.
To verify that everything was correctly configured, I added to the scene a 3D cube, and, following Microsoft suggestions, I added the ObjectManipulator and NearInteractionGrabbable components to the cube. When I connect the HoloLens 1 to Unity through Holographic, I correctly see in the Hololens 1 the cube in the scene. Also, if I move the pointer over the cube, it correctly detects the presence of the cube. However, no gestures are recognized and therefore I cannot have any type of interaction with the cube. Even adding a bounding box with handles doesn't change the situation. The handles are recognized (their icons change) by the pointer, but then gestures are not identified and the presence of my hands in the FOV is not detected.
I tried creating a new project several times starting from scratch, changing profiles and configurations, but the result is always the same. Is there something I'm doing wrong or missing?
thank you for your help

Hi, the only solution i found was to use legacy XR, new XR plugin cause gestures dont work so i uninstall from package manager all XR plugin managment.

To troubleshoot gesture recognition issues with MRTK 2.8.3 in Unity 2019.4 for HoloLens 1:

1. Check MRTK Profiles: Verify that the DefaultHoloLens1InputSystemProfile is correctly applied.
2. Update Software: Ensure you're using compatible versions of MRTK and Unity.
3. Verify Input System: Confirm the Input System is active and configured for HoloLens 1.
4. Check Gesture Settings: Make sure the desired gestures are enabled in the Input System Profile.
5. Rebuild and Redeploy: Rebuild your project and redeploy it to HoloLens 1.
6. Test Samples: Try running MRTK sample projects to see if gestures work there.

If issues persist, consult the MRTK documentation or Microsoft Mixed Reality forums for further help.
