This is what it looks like every time. Changed pi’s, changed wifi cards, changed power supplies, wired wifi cards separate etc etc. Still same chopped off video as when I started. I tested the pi cam on the pi 3b using other software and it was fine.
Interesting to note that briefly when I begun this whole thing I did get full frame video…just for a while. That was before I even had wifi cards with the right chipset.
Whenever I tested a new build without a proper voltage (both air and ground pi) this happened to me too. So, try using a dc-dc converter (Pololu, if possible) that can output 5A and 5.25V under full load (wifi card at txpower=58 and camera connected)
which polulu do you use ?
I’m using Okystar step-down, because Pololu was out of stock locally.
I think, it’s equally good quality.
First one, with voltage display is for my ground setup.
Good ones are essential I know. The cheap ones off Amazon I’ve tried with the heatsinks become mini heaters within seconds with just the pi and wifi card hooked up. I guess they just can’t handle anything close to the rating slapped on them.
(still need to retest my stuff with different power)
