On the early stages of the beta-testing (until the Utility software is working) the [Connect] button can be ignored.
In order to test a single K-Ceptor with the testcube.blend
you have to launch the notochord from the SBC's terminal environment using the IP address of the PC running Blender as a parameter.
Then just press [Receive] on the Blender add-on (without hitting ENTER) and the 3D object should rotate accordingly to the physical K-Ceptor.
Side note:
We are aware that the UI as it is now is not really intuitive.
One of our intentions for the beta testing program is to understand which changes should be applied in order to obtain a smoother user experience.
(For example hiding the big [Connect] button if there's no sense on pressing it, or not asking to press ENTER if you don't have to 😅)
Once we have a couple of suits working we can start discussing these changes.
