How to use Flight Instruments inside an Observer Model

Hi,

I am using an Observer Model (https://de.mathworks.com/help/sltest/ug/access-model-data-wirelessly-by-using-observers.html) to monitor my simulation. I'd like to use flight instruments from the aerospace blockset (https://de.mathworks.com/help/aeroblks/flight-instruments.html).

The connection does work as usual, but once running the simulation all instruments are displaing "no data availabe". Is there a way to use these instruments inside of the observer model?
