Not properly responding to queries.

Hi, i got the latest version of the repo and when i run my script or the async example from the docs i get a single response from the adapter and aftert that only "None" as a response. I'm struggling with it for a really long time now. Maybe someone has an idea what the problem is? Im using a raspberrypi 3b+ with debian 10 buster.

Response:

0.0 revolutions_per_minute None None None
