Here is the thingy solution to attach motion like invense and nordic semiconductor

Please my solution to work with the thingy from semiconductor:

I created a dll permitting to work with unity and the thingy.

Add an objet and attach the dll as in the docuentation.

you can even debug the dll if your build the dll projet and you attach to the unity editor.

is it possible to pass it as an asset on your asset store ;->>
