Mavros and Unsupported FCU on Intel AERO RTF

Hello everybody!

I am trying to command my drone, an intel aero RTF, via mavros. So I have the drone running roscore, and my companion computer running mavros. So to resume:

I sourced the environnement (opt/ros/indigo/setup.sh) on my drone . In this document, I put ROS_MASTER_URI=http://192.168.1.1:11311 and ROS_HOSTNAME=192.168.1.1, the drone IP. https://github.com/intel-aero/meta-in...
I launched roscore, on the drone.
On my computer, I sourced my environment in catkin_ws with source devel/setup.bash.
I modified ROS_MASTER_URI=http:/192.168.1.1:11311 and ROS_HOSTNAME=192.168.1.2.
I launched roslaunch mavros px4.launch fcu_url:=udp://@:14556 gcs_url:=udp://:14556@192.168.1.2:14550. 192.168.1.2 is the IP of my computer when I am connected to the Intel Aero Wifi.
In an other terminal, after sourcing my environment and modifying ROS_MASTER_URI and ROS_HOSTNAME, I launched my ROS Package with rosrun myprogram takeoff.

After all this steps, the only thing I can see is "Mode: Unsupported fcu" in the mavros terminal. I can't solve this... Could someone help me pls... It was not simple to arrive here, and I can't go further... I know that my program is good, because I can simulate it with gazebo and a 3D IRIS without problem.

What you see in /diagnostics? I suppose that you do not have a connection.

rostopic echo -n1 /diagnostics

Also i don't understand what you want with udp://@:14556 - it is equal to udp://@ because remote host is required. Next you setup gcs proxy to bind on that port, why?

Thanks for your help vooon! Sorry for the delay, I was ill... In fact, I don't have connection with /diagnostics. These parameters for fcu_url and gcs_url are the result of my research on the net because it is my first project with ROS. I have tried many things, but I never got connection.
