hi
I’m researching in this page
http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

But my method is a different.i not used to your raspberry image. i’m use usb to connect between raspberry and pixhawk. i no problem when using from lan to connect to raspberry pi and communicating between pixhawk and mission planner is successfully. but, when i connected to raspberry with wifi, connection failed. the last code is:
mavproxy.py --master=/dev/ttyACM0 --baudrate 57600 --out my_ip:14550 --aircraft MyCopter
please help me to do it. thanks.

To work with ArduSub, the best approach is to use the companion image, take a look on our software components webpage.

It’ll work if my_ip is your surface computer through wifi, probably the problem is your wifi router blocking 14550 port.
