I am using a Pixhawk, configured using QGC. My goal is to use MAVROS to publish data to the prescribed topics, then feed those topics into QGC for display, and hopefully two way communication. But for now simply display purposes will do.
For now I’d like to get it working on the same computer, then have it working over a wifi network.
I have the pixhawk plugged into USB port to my linux machine (Ubuntu 16.04.2) via the telem2 port using an adapter.
WITH QGC CLOSED I can successfully run:
To solve this I had to set the parameter CBRK_AIRSPD_CHK = 162128 in QGroundControl. This ensures that the absence of the airspeed sensor is ignored.
I have successfully implemented this in a slightly different configuration: FCU (pixhawk with px4) <—> Companion Computer (Intel NUC) <—> QGroundControl on Linux Computer. I have outlined it below, and included useful links at the end of the post.
