Hi @chuck, thanks for the clarification. In fact this SDK (Tobii Pro SDK) is specifically designed to only work with Tobii Pro devices such as TX300, TX-120, etc and *NOT* the Tobii Tech range of trackers such as EyeX or C4.
Accordingly, these python bindings will not work with the EyeX.
Hopefully you manage to get up and running with our new low level Stream Engine… best of luck!
