DCS Lua Export and socket question

Hello,

I apologise if there is already an answer in this forum that i could not dig out :)

I am exploring DCS export via lua script for a simple project,

my goal is to capture data in real time from DCS (this part works fine) but also to input

some data back in, in example joystick and throttle movement.

If i am correct, LuaExportBeforeNextFrame and LoSetCommand should do just that,

however setting anything with LoSetCommand in LuaExportBeforeNextFrame does nothing on my side

even this hard-coded sample

function LuaExportBeforeNextFrame()

-- Works just before every simulation frame.

LoSetCommand( 3, 0.25) -- rudder 0.25 right

LoSetCommand( 64 ) -- increase thrust

LoSetCommand( 8 ) -- External view

end

Area there some kind of restrictions, or there is an other lua script that DCS uses for input?

Thanks
