I have a Pixhawk that was given to me. I was told that the altitude would not hold very well. I gave the guy one of my spares and he loaded it in to his quad and it held altitude quite well.
So now Im trying PX4 for the first time, along with QGC and I’m hoping to be able to check the barometer is working well, before I put it into a frame. I found there is a way to have the altitude reading show up in the “Fly” tab of QGC, but it seems to just stay at 0m, so i’m actually starting to wonder if that is based on GPS altitude.
I have “Altitude-Rel” and “Altitude” ticked on.
Thanks in advance, Nicholas
