Plus App connection issue with NDI Polaris Lyra

[AdamDomafoldi]

Hello,

I have spent a lot of time on this, but I have not been able to figure it out.

The NDI Polaris Lyra is on the same network, and I am able to use it with the NDI tool applications. However, when I try to use it with the Plus App, the app fails. The logs indicate that it is trying to connect via serial.

Do you have a configuration example file or tutorial on how to reconfigure the Plus App (v2.9) to connect properly? The Polaris Lyra is using TCP/IP and not serial connection.

I have attached two screenshots of the error message. I also tried running it from the command line in the hope of seeing a more verbose error message, but no luck so far.

Can you attach your config file?
If you haven't already, you need to specify the NetworkHostname and NetworkPort. See: https://pluslib.readthedocs.io/en/latest/devices/DeviceNDI.html#device-configuration-settings

    <Device
      Id="TrackerDevice"
      Type="NDITracker"
      NetworkHostname="192.168.0.30"
      NetworkPort="8765"
      ToolReferenceFrame="Reference" >
      <DataSources>
        <DataSource Type="Tool" Id="Stylus" RomFile="NdiToolDefinitions/8700248.rom"  />
      </DataSources>
      <OutputChannels>
        <OutputChannel Id="TrackerStream" >
          <DataSource Id="Stylus"/>
        </OutputChannel>
      </OutputChannels>
    </Device>

@Sunderlandkyl Thank you for your help — the static IP configuration and the additional setup steps seem to be working now.

I have another question. Now that I have streaming from the Plus App into the 3D Slicer OpenIGTLink module, I would like to either visualize the needle movement or add a simple virtual object (for example a cube) that is transformed in real time using the Polaris tracker data.

Do you havea a sample project/tutorial I could use for reference?

Right now everything seems to be working, but I am unable to perform a pivot calibration because it appears that the tool is not being detected properly. I have already gone through the SlicerIGT tutorials and documentation.

I have attached my configuration file and two slicer screenhosts.

[PlusDeviceSet_Server_NDIPolaris.xml](https://github.com/user-attachments/files/27523278/PlusDeviceSet_Server_NDIPolaris.xml)

[Sunderlandkyl]

You can create a simple model using the CreateModels extension from SlicerIGT. Once you have that you can drag and drop the model onto the tool transform in the transform hierarchy.

[AdamDomafoldi]

@Sunderlandkyl Yes, I have tried that already, yet the cube is not moving. Is there a way to debug it from the 3D Slicer end?

[Sunderlandkyl]

Can you confirm that the transform is updating in the transforms module?
