HI @gustavods07, thanks for your query. In theory, you should be able to use the EyeX with the Tobii Pro SDK however please bear in mind this is deprecated hardware and you would need to purchase a special unlock licence for this purpose.
If you are interested in receiving a quote, please send your request and project intentions to: [email protected]
In the meantime, you are free to use one of our other SDK offerings that will work directly with the EyeX such as the Tobii Core SDK or Stream Engine API.

Please do let us know if we can provide any further information. Best Wishes.
