Is it possible to use MAVROS to only convert messages from Mavlink messages to ROS messages and vice-versa? I do not want a connection to a FCU, like you are forced to have (I do not have a Mavlink enabled drone).
Thanks for any help!
To answer xlightx: It has indeed been a time, and there might a better solution than the one I'll describe. I was working on an DJI drone and we wanted to communicate with it over a very slow connection (a mobile device using the remote controller) with DJI Onboard SDK ROS (running on the drone's Ubuntu computer). My solution was:
Yeah, that might be enough. I had to go through all the extra work, because I was basically converting a DJI drone autopilot to behave somewhat like a Mavlink autopilot. The potential end goal being making a DJI drone controllable through QGroundControl (which would require a whole lot more work, because of big differences in how data is interpreted on Mavlink and DJI drones. So my thesis stopped once we had a working Android GCS prototype, and were able to send Heartbeat messages to QGroundControl).

It's unclear why you want to do this. If you want to simulate a drone or rover, you might use SITL and mavproxy with mavros. (That's how we're simulating a rover.) See: http://ardupilot.org/dev/docs/sitl-si...
We are using a DJI drone, with which we interact only with ROS messages (sending commands/receiving position/...). The messages will be sent over the RC in Mavlink format. What we now need is only to convert those Mavlink messages to ROS and vice-versa.
This was a long time ago, but did you find any solution? Or is mavros an overkill if I just want "basic communication"?
