Cannot connect to real drone running Arducopter via dronekit-python

[gaetanokent]

Hi Everyone,

I’ve been trying without success to connect with a simple dronekit-python script to my drone running navio2+rp3 and Arducopter. Connection to the drone works perfectly with both QGroundControl or APMPlanner … I connect directly via the Wifi of the Raspberry since both the drone and my laptop running QGC or APM are connected to the same wifi router at home.

On Ardupilot running on Navio2 I have edited the file sudo nano /etc/default/arducopter with the configuration #TELEM1="-A udp:192.168.1.108:14550" where 192.168.1.108 is the IP address of my laptop.

The droneKit script I’m using is the basic:

vehicle = connect(‘192.168.1.114:14550’, wait_ready=True)

where 192.168.1.114 is the IP address of the drone on the wifi network. This script is saved on my Connect.py script and I run it on my laptop (where normally I run QGC or APM)

Unfortunately this is not working. I tried both uptions: using tpc and upd (when using tpc I simply use ‘tcp:192.168.1.114:14550’ when calling the connect function). Both are not working. I get:

Case UDP: Traceback (most recent call last): File "Connect.py", line 15, in vehicle = connect('192.168.1.114:14550', wait_ready=False) File "/Library/Python/2.7/site-packages/dronekit/init.py", line 3159, in connect handler = MAVConnection(ip, baud=baud, source_system=source_system, source_component=source_component, use_native=use_native) File "/Library/Python/2.7/site-packages/dronekit/mavlink.py", line 130, in init self.master = mavutil.mavlink_connection(ip, baud=baud, source_system=source_system, source_component=source_component) File "/Library/Python/2.7/site-packages/pymavlink/mavutil.py", line 1670, in mavlink_connection return mavudp(device, source_system=source_system, source_component=source_component, input=input, use_native=use_native) File "/Library/Python/2.7/site-packages/pymavlink/mavutil.py", line 1015, in init self.port.bind((a[0], int(a[1]))) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 228, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 49] Can't assign requested address

Case TCP:

The reason why I need to use dronekit-python is to get telemetry data from the drone and upload missions written in code, directly from my laptop. Do you know where am I doing a mistake? Should I configure something different in Arducopter?

hi , i'm facing the same problem .Did you find a solution ?

When connecting dronekit to sitl the procedure is the following: in sitl add output 192.168.1.10:14550. (the ip of the computer you want to connect from) in dronekit, connect to 192.168.1.10:14550 (yes, your own ip)

you could give it a try (i.e. connect to 192.168.1.108:14550).

I don't understand how my computer finds the way to sitl. If someone can explain I'm happy to listen :)
