Python: isConnected() returns True after the scanner is turned off / in stand-by

[Contused]

I recently noticed that isConnected() does not work how I thought it would behave.

Behaviour: -I connect to the scanner with cast.connect(ip, 5828, "research") -I check for cast.isConnected() status every 10sec. in a thread -If the ultrasound probe is going to stand-by or is turned off by holding down the power button: the app shows "Casting information not available". To my understanding the connection is closed.

Expected: If I check with isConnected() I should get True if there is an active connection between scanner and my software If I check with isConnected() I should get False if there is no active connection between scanner and my software

What happens instead: After the scanner is turned off/ in stand-by and the app shows "Casting information not available" I still receive True when checking cast.isConnected(). Also sometimes during scanning I receive False when checking cast.isConnected() in a seperate thread.

Data: Device: C3HD3 Firmware 11.2.0 App: 11.2.0 Python Software CAST: 11.2.0 (cast.dll, cast.lib), pyclariuscast.pyd from last available release

Question: Is this a bug or am I wrong on the expected behaviour?
