however the port and address are depends on your system.

thanks. I understand this, but when I plug in the telemetry onto my computer, what IP address do I use. Where can I find the IP address of the FCU? I am using rc telemetry for transmission |
@zhahaoyu You could check your PC IP address using

Thanks @weiweikong. Now I understand the structure. I tried to use the When I start Mavros, everything was fine. But if I open QGC, then it automatically listens to the same telem port, and mavros crashes. So how can I create the connection between QGC and mavros |
the
means QGC will then be connected via UDP to port 14556.

I followed your instruction, here is the launch file I used
and mavros still crashes with following error message when I start QGC

I am now sure whether above information means QGC tried to connect FCU with serial port. If it was true, QGC or |
I believe QGC is trying to use the serial port. When I use QGC with ROS in SITL mode, everything works fine. I just don't know how to do this with real pixhawk fcu. |

Hi, I have a similar problem, I got an FPV Radio Telemetry Ground Module and I want it to communicate with the telemetry that owns the Iris drone. When I connect the telemetry (Ground) to my ubuntu pc and turn on the drone does not start the Qground station. Why is this problem? Do I have to install any drivers? |
