Camera not idle , cant start a new exposure

[Nik A]

Hi,

Camera’s status sometimes stays as *exposing and not as *idle, even after I downloaded an image, and therefore is not able to start a new exposure. I get the following error message, and the only solution worked so far is to disconnect/connect camera and its filter wheel.

There is not much on NINA side that can get around this problem. All ascom camera drivers are handled in the same fashion as per the ascom specs and this seems to be a specific behavior to this driver which is not part of the ascom spec
