Connect Dronekit to MAVproxy over LAN

[AlexanderMarinsek]

I am trying to run a Dronekit-Sitl simulator on my PC and access the simulator from an Odroid companion computer over LAN. My PC is running Ubuntu 16.04 and the Odroid is using Lubuntu.

The following case works:

1. On the PC run dronekit-sitl copter-3.3
2. On the Odroid run mavproxy.py --master=tcp:<pc_ip>:5760 --out=udp:127.0.0.1:14561
3. On the Odroid run python my_dronekit_code.py

When I want to connect APM Planner in order to monitor the simulated drone's movements, I would typically need to add a step after the first one:

• 1.2 On the PC run: mavproxy.py --master=tcp:127.0.0.1:5760 --out=127.0.0.1:14550 --out=127.0.0.1:14551

However when I do this and try connecting MAVproxy on Odroid to one of the new output ports (udp:<pc_ip>:14551), I can no longer access the simulated drone - I get the output Waiting for heartbeat from <pc_ip>:14551.

Both ports have been opened to the public using sudo ufw status verbose:

[sudo] password for jawa: 
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

14551/tcp (v6)             ALLOW IN    Anywhere (v6) 

Notice: I have tried connecting the Odroid directly to the PC, without step number 2 (running MAVproxy on Odroid), but I always get an exception. This problem has already been debated.

Change the order, run your 1.2 command before 2. And change 2 to:

On the Odroid run mavproxy.py --master=udp::14550 --out=udp:127.0.0.1:14561

I'm not sure you understood me. To clarify, the bellow steps result in an error:

1. On the PC run dronekit-sitl copter-3.3
2. On the PC run mavproxy.py --master=tcp:127.0.0.1:5760 --out=127.0.0.1:14550 --out=127.0.0.1:14551
3. On the Odroid run mavproxy.py --master=udp:<pc_ip>:14550 --out=udp:127.0.0.1:14561

Failed to connect to udp:<pc_ip>:14550 : [Errno 99] Cannot assign requested address.
