I am running QGroundControl on Ubuntu 14.04. While I try to connect my ErleBrain 3 Hexacopter(with ArduPilot), it is not getting recognised by QGroundControl. I have followed the official documentation and have added a new Comm Link of UDP type with listening port 6000 as described.
I even followed the instructions given on the topic at the link http://forum.erlerobotics.com/t/qgroundcontrol-dont-connect/2904, but the issue is still unresolved.
This is the error I am facing.
