Hi everyone,

I'm trying to setup the tobii and matlab in order to record the data but I get an error message "Warning: Unsuccessful read: The specified amount of data was not returned within the Timeout period. 'udp' unable to read any data. For more information on possible reasons, see UDP Read Warnings. "
The eyetracker is the 4C and it works fine by itself but for some reason matlab is unable to find or read the data recorded from tobii. Does some of you encoutered this problem before? If you have any advice on how to solve the problem it would help me a lot.
I have attached a video of the problem

Thanks!

Dear all,

I am doing an experiment related to tobii and I came across this software. However I received an error while running. Also I am new to matlab but I would still like to learn the work flow of the software because it would really help me in my study.
I have attached the image of what I get during my program run. Please help me fix it. Also, I am unable to understand the workflow of this code. Which files or program shuold be run first ?

+### **V 3.1bis.** 
+The Tollbox has been  posrted also in the EYEX SDK, which shoulld be more compatible with the new **Tobii 4C**.
 ### **V 3.1.** 
 The calibration routine has been extended to 3D experiments! The previous version required a monocular calibration for each eye, covering one eye while calibrating the other. The actual version explois the characteristics of a 3D display, to show the target to a single eye, while displaying a uniform background to the other eye.

 * Ready-to-use and **customizable routine** for positioning the subject and calibration

+A number of connection bugs have been resolved, now data transmission is more stable.

 ### **V 2.0.** 
 The Toolkit is now more "fault tolerant". If the connection goes wrong or some connection problems happen while working, **the Toolkit tries to reconnect to the device**.
 Also, we added in a separate .zip file, an **[Experimental Suite][9]** containing sample code to replicate the experiments proposed by researchers, and to exemplify the usage of the device. In order to use it, extract the file within the same folder where the Toolkit is.
