SDK Samples and connection to eye tracker

[Ufuk]

Hi,

I am trying to run SDK samples with my new tobii eyex. Samples are compiled and run well, but it seems that connection cannot be established between eyex engine and the samples. I can successfully use the device with the “eyex for windows” software. But when i compile and run MinimalGazeDataStream sample, it only says trying to connect and nothing happens after. Same thing happens when I compile the ActivatableButtons example, it says “Mouse Only :(” near the window title(I assumed thats only appear when it cannot connect the tracker:).

Am I missing some configuration?

Hi,

What versions of the softwares are you using?

The EyeX Engine 0.10.0 requires SDK version 0.31 and vice versa, because of API changes.

You can check in the MinimalGazeDataStream in the main method if there is a function call to txInitializeEyeX, then you have SDK version 0.31, and check the engine version in the EyeX Settings panel.

Thank you very much!!

I downloaded the 0.10.0 version of the engine and that solves the problem 🙂
