I have APM Planner up and running on Ubuntu 16.04. When I attempt to connect to the flight controller (Navio2 on Rapsberry Pi 3) I get the "Error on socket:Connection refused" message.
I've disabled the firewall on the PC, added the IP address of the Pi to the /etc/hosts file, but still get the error.
I've searched the web for solutions but there are many complicated posts and I tried a few unsuccessfully then decided to come here and ask.
The same setup works connects using APM Planner 2 on Windows, but I need the linux version to work.
Can someone please tell me a solution for this frustrating situation?
Thanks,
Paul
