How do I 'connect' to a COM port when using mavlinkio 'connect' , only UDP port is documented

12 visualizaciones (últimos 30 días)
I wish to use Matlab's MAVlink libraries to listen and talk to a robotics platform: specifically ArduBoat which links to its ground station (MIssion Planner running on a Laptop) using the MAVlink protocol over an external radio link. The radio at the laptop has a USB cable and appears as a COM port on Windows.
Matlab MAVlink libraries use mavlinkio to make the initial connection, with
but there is no documentation for connecting via Serial Port (so the software can link to the radio) rather than UDP.
Is there an exisitnig solution for this, that is, to enable Matlab to listen (and talk) to the Ardupilot / (Pixhawk hardware) family of robotic platforms
Thanks in Advance

Hi Philip,
Serial port connection is not supported out of box. You could use serialport object to exchange binary data and use mavlinkio/mavlinkdialect objects to serailize and deserialize the messages.
You can install the UAV Toolbox PX4 support package and check the "HelperPX4" function used in that implemented a serial based mavlink communication for an example.

Hello Jianxin,
Perhaps I didn't explain the issue well, as your suggestions are rather complex for a simple rrequirement. A suitable answer I received via a different route was
which is what is required. Hope this clarifies what I was searching for
