How to send remote commands to a raspberry pi via MAVLink?

[Ak21]

I saw this wiki page - http://dev.ardupilot.com/wiki/raspberry-pi-via-mavlink/

It opens  MAVProxy on the raspberry pi and helps to control the Pixhawk through MAVLink commands. Right?

How can I control the pixhawk through the raspberry pi by sending commands to the raspberry pi over wi-fi for example? I don't have to then ssh into the raspberry pi and just send the same commands. But then raspberry pi needs to get the data from a wifi-dongle I guess and then send it to the px4. How to do this?

I am interested in the same question too.
Anybody who can help us?

You can have the RaspBerryPi listen on a ip socket (connected via WiFi) and then proxy that information to the Pixhawk

You can use  a GCS like QGC or APM Planner 2.0 to connect to the Raspberry Pi

ie PHRaspPiGround Control Station

You could even just connected a WiFI dongle to the Pixhawk (see http://www.ebay.com/itm/Wireless-Wifi-Telemetry-Module-with-Antenna-for-Pixhawk-APM-Flight-Control-CC3D/251978180205 for example)

PHGCS 

They are all talking using the MAVLink protocol http://mavlink.org

You could have something like a socat command running on the pi that forwards a UDP connection to the pi to /dev/ttyAMA0

I think something like this could get you started:

socat -d -d UDP-LISTEN:14550 /dev/ttyAMA0,raw,echo=0,crnl

Just have this automatically run on the pi and then anything you send to your pi over the UDP connection will be sent to the serial port and vise versa.
