Re: [Flightgear-devel] Output communication problem
Hello, finally I had time to try it, and it works fine with the native-ctrls protocol. Thank you very much for your help.

What protocol you are using for this connection? If data to FG is sending via native-fdm then FG mast send controls via native-ctrls protocol.

[Flightgear-devel] Output communication problem
Hello, I have encounterd a little bit strange thing in Flightgear v1.0.0. I'm implementing I/O communication with Flightgear using native-fdm protocol and TPC sockets. I would like implement following communication. 1. In Matlab - Simulink are computed positions, velocities etc using Simulink aircraft model. These data are consequently sent to FG (set to use external model). 2. Content of internal FG variables is sent back to Matlab to obtain control inputs from /controls/flight variables and other values which are used as inputs of aircraft model. I think it should be possible to implement this, because although when I'm using external model, control internal properties are filled with values from joystick etc. And now I'm getting to the mentioned problem. When I'm using external model in FG, data are received from Matlab and everything works fine. However there is problem sending values in opposite direction (FG to Matlab). I have observed various variables in received FGNetFDM structures and all of them were set to zero during whole simulation, but they should have been assigned nonzero values. I tried to send data from FG with external model using generic protocol and got the same result. I would like to ask whether this behavior is bug or not, and whether is there some way how to work it out. Thank you very much for your help.
