I have a new replacement P2 with the same setup as my original: P2 + Zenmuse + GoPro AVL58 Tx DJI FPV Hub iOSD Mini All of the software for all of the devices is up to date. On my first test flight (at a safe height of just 3 feet), it didn't feel like it was in GPS mode. I was just trying to maintain position with some gentle moves but it was drifting slightly. After a few minutes of relatively stable flight, the lights flashed yellow then red for a second and back to green which I believe would indicate a compass issue. Then it started to drift and I brought it down for a slightly bumpy landing before it could pick up velocity and do any damage. I packed up the P2 and returned home to do a little troubleshooting to see what was going on. I didn't want to risk another flight. I am getting a clear picture with live data overlaid. I have calibrated the compass (again), and the lights show green on startup. The iOSD indicates I have 7-8 satellites. I have my switch set in the top position for GPS mode. BUT, my OSD shows ATTI mode - and it stays like that even after 2-3 minutes. Any idea as to why I can't get into GPS mode (at least according to the iOSD)? What is going on?
