Hallo everyone i followed the ROS starting guide : https://docs.emlid.com/navio2/common/dev/ros/
And all went relativly well until i got to “Running mavros node”.
I tryed to enter the command:
pi@navio: ~ $ rosrun mavros mavros_node
_fcu_url:=udp://:14650@
_gcs_url:=udp://:14551@192.168.1.189:14550
were i found my first Problem - “192.168.1.189:14550” is supposed to be the ip and port of the GCS computer, but is that my normal wifi ip ?
Because that wouldnt make much sense iam connected via a 433MHz 3DR Telemetry antenna to my Drone not via wifi. In fact the drone and the Computer are even connected to different Wifis.
Regardless if i ignore my doudts and just try to enter the wifi adress of my Computer with the GCS-Software i get:
[rosrun] Couldnt find executable named mavro_node below /opt/ros/indigo/share/mavros
Does anyone have a clue to make it work? Do i need a wifi telemetry connection to the drone or something? Or does this error mean something completly different?
