I am running Pixhawk with firmware 3.1.5 with extra build 2.2 on Miniim OSD. Actually I am running 2 machines with Pixhawk and OSD. My problem is as soon as I arm the home direction arrow and the home distance stops receiving data, . As soon as I disarm they start responding again. I have the same problem with both machines so it doesn’t appear to be a hardware issue. Everything is genuine 3DR products.
