WiFi Bridge with MavProxy
If you are using a companion comuter that is connected to Pixhawk, or a MAVLink-equipped controller, and you need to setup a mavlink bridge, you can use MavProxy.
As quoted from the main MavProxy guide, MAVProxy is
A UAV ground station software package for MAVLink based systems
One of its many features is to establish a communication bridge between machine that is running MatMav (or any other GCS) and the vehicle (e.g. with Pixhawk).
Follow this guide to install MAVProxy on the companion computer, e.g. RPi or ODroid.
On the companion computer establish the communication bridge by using the following command
mavproxy.py --master=/dev/ttyAMA0,57600 --out=udpout:192.168.1.2:14550
/dev/ttyAMA0 is the serial port address. The baud rate
57600 can be changed according to the setup. The remote port
14550 and IP
192.168.1.2 (of the ground station computer), can be adjusted, too.
Automatic startup of the WiFi Bridge
To start-up the bridge automatically after boot, follow this link.
Now, you should have a WiFi bridge between your laptop and the vehicle.
