I am very new here and am currenty trying to work with mavros.
So i set everything up and it seems quite a lot works. BUT i have a few questions and would be very happy if someone can help me:
When I launch: roslaunch mavros px4.launch I always get the warning: No GPS fix.
And I think because of that, I am not able to ask for local NEDs etc.
I can run: rostopic list and for example: rostopic echo /mavros/state
I am sure that I have a GPS signal (QGC proves it)
What could be my mistake?
And another, very basic question:
When I run: roslaunch mavros px4.launch and then rostopic echo /mavros/state, what are all these headers? Why is it continuosly generating more headers? Why don’t I have one header for my pixhawk?
Thanks a lot!
