Has anyone been able to subscribe to the topics that are published by the roscopter node? I have established a custom node that subscribes to the /state topic (it shows this on rqt_graph), however the callback in my custom node is never reached. It is a strange error because I can call rostopic echo /state and it will show the output perfectly however these values are not passed into my custom node.

btw I am using these nodes on a intel edison.

thanks,

JB

update-

The only way the callback function is ran is when I run both nodes separately through rosrun. When i launch both nodes from a launch file the callback is not ran. I am going to to try creating two launch files and then combining them to see if this works.
