    I’m using a Tobii 4C eye tracker with the Tobii Pro SDK .NET (C#) bindings. I’ve received a license key that enables the use of the professional sdk. I connect to the eye tracker, apply the license key, and then set 2 events: GazeDataReceived and EyeImageReceived. The GazeDataReceived event works correctly, however, the EyeImageReceived event is never invoked.

    Here’s part of the license key that shows the professional sdk support:

    “enables”: {
    “featureGroup”: “professional”

    Any assistance would be appreciated.

    Hi @gparkinson,

    Please note that for issues related to Tobii Pro SDK, you should get in touch directly with Tobii Pro Support
    at their own channel @ https://www.tobiipro.com/contact/support/

    However, it might help if you try running the specific example provided for the EyeImageReveived class @
