New eyetracking demo not working with tobii

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): v2021.2.2
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:
I’m trying out the new eyetracking features and started with the builder eyetracking demo. I set up the eyetracking properties with a Tobii Fusion Pro 120 Hz leaving the license file and serial number blank. But when I run it I get the below error. I do not have trouble running the calibration through Tobii Eye Manager.

What did you try to make it work?:

What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.

It seems like psychopy (which uses the tobii-research Python package) is not able to connect to your eye tracker. Does this happen when Tobii Eye Manager is running at the same time, or even when the Tobii Eye Manager is not running when you start the experiment?

If neither works, are you able to connect to the tracker directly using one of the Tobii Python examples directly? This would help determine if the issue is specific to the iohub use of tobii_research and your tracker, or a more general issue.

Thank you

Turns out I was putting the name in incorrectly (Tobii Pro Fusion vs Fusion Pro), so the python examples helped me to set it up.

Thanks!
