Setup Rpi3 and Establish communication between Dropix flight Controller and Rpi3

Hello all,

I am working on a project where I would like to use Raspberry pi 3 (Rpi3) as a companion computer for Dropix Flight controller. I want to send the commands to flight controller from MATLAB script via Rpi3 using MAVlink protocol. To do that, I am in process of setting up my Rpi3 board. I am following this page
http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

I was able to flash the Apsync image on SD card and then insert SD card onto Rpi3. I was able to login the Rpi3 but am not able to check if the board is connected to internet. ping google.com gives “temporary failure in name resolution”.

Any help is appreciated! Thanks.

you do not have to install packages if you are using APSync
