Getting started

I am trying to get the sim working but I have some problems.
When I start the rosflight_io node like follows (rosrun rosflight rosflight_io _udp:=true
) I becomme this error Received 0 of 0 parameters. Requesting missing parameters…. The command rosservice call /param_set “name: ‘FIXED_WING’ value: 1” gives me exists false.

How are you launching the simulation?

Welcome @salem. Also, are you using the last release (i.e. did you sudo apt install it), or are you using the latest source?
