I'm using a pixhawk and I'm using mavros hydro. Right now I just have pixhawk connected to ESCs, a remote and my laptop. I'm trying to see what RC inputs are corresponding the remote stick position but /mavros/rc/in shows me nothing.

What mavros publish at /diagnostics topic?

Also note, that development for hydro stopped, you should look plugin docs for 0.8.

a lot of things show up, I don't know how to include them all in the comment. Is there anything in particular I need to pay attention to? Thanks

Use pastebin.

Hmm, strange. Heartbeat is ok, but there no SYSTEM_STATUS and many other messages. Try rossys rate --all 10, but not sure that it helps. Also try connect via USB and use latest mavros .0.11.1.

I think my team is using some other software packages that are not supported in indigo so I'm not sure if I will be able to use the latest mavros. And right now it is connected to my laptop via USB.

Fix: mavsys rate --all 10, not rossys. Also master still may be built for hydro because i use Travis, and travis stuck on Ubuntu 12.04. But i got lots of errors on jenkins.ros.org, so decided stop development for hydro.
