Thank you for this suggestion Alex. However, TobiiGameIntegrationApi.GetTrackerInfo() is giving the firmware version and generation details which is not that useful.
Do you mean to say that it is possible to fetch the eye tracker name and hardware version details from any other language or SDK?
If even that is possible, I can fetch those details from there and create a DLL to pass those details to my Unity C# script.
I would really appreciate some more help here.
