On the PXFmini on a RPi0 running Frambuesa, I followed step by step the ROS video tutorial, being able to compile ros_erle_takeoff_land without any problems, but then running
rosrun ros_erle_takeoff_land ros_erle_takeoff_land fails to connect to the master, and same thing running
rostopic list :
I have a monitor connected to the Pi displaying the process that are running, and I can see that each time I run either
rosrun ros_erle_takeoff_land ros_erle_takeoff_land or
rostopic list the process roscore ends.
It seems to me that ROS is not configured correctly. Any ideas on the cause of the problem and how to fix it??
