Tool state window display in fCal not working

[acc2024]

Hi!
I have added a new device to PlusToolkit. Currently I've only created the bare minimum in vtkPlusMyDevice.cxx/h. I followed the guide provided on https://plustoolkit.github.io/devicecode and used the vtkPlusNDITracker as an example. When I run fCal and connect the tool, I am able to collect data from the sensors and send it to the log. However, on the fCal UI, I can't see the tools status, see the following screenshot

Using the original vtkPlusNDITracker, it displays the tools correctly see the image below:

In my device file I use:

this->ToolTimeStampedUpdate("ReferenceToTracker", toolTransform, toolFlags, this->FrameNumber, toolTimestamp);

The aim is to perform a stylus calibration using fCal. Currently the button "Start" under the tab "Stlus Calibration" is disabled even though I can see that the pos and orientations values from the three sensors are correctly displayed in the fCacl log file.

Here is a snippet of my configuration file:

<Device
      Id="TrackerDevice" 
      Type="MyTracker"
      AcquisitionRate="5"
      ToolReferenceFrame="Tracker"
	  IPAddress= "xx.xx.xx"> 
      CheckDSR="true">
      <DataSources>
        <DataSource Type="Tool" Id="Reference" BufferSize="1500" PortName="0" AveragedItemsForFiltering="20">
          <CustomProperties>
 ...
 </DataSource>
        <DataSource Type="Tool" Id="Probe" BufferSize="1500" PortName="1" AveragedItemsForFiltering="20">
          <CustomProperties>
            <Manufacturer>
</DataSource>
        <DataSource Type="Tool" Id="Stylus" BufferSize="1500" PortName="2" AveragedItemsForFiltering="20">


...
 </DataSource>
      </DataSources>
      <OutputChannels>
        <OutputChannel Id="TrackerStream">
          <DataSource Id="Reference" />
          <DataSource Id="Probe" />
          <DataSource Id="Stylus" />
        </OutputChannel>
      </OutputChannels>
      <Parameters />
    </Device>
  </DataCollection>

Do I need to do any additional code changes to perform a stylus calibration other than the changes mentioned above to add a new device and a configuration file?

I would appreciate your feedback to fix the issue!
Thank you!
