I'm getting a sequence I don't quite understand. I'm in NAZA mode with IOC and both switches up (IOC off and GPS mode). Fresh battery (above 90% in Vision App). I get a GPS lock with about 8 sats. I am in a height restricted zone and I get a warning on the Vision app that I am restricted to between 20 m and 120 m height. The rear LED sequence I'm getting is green, rapidly flashing red, green, etc. Flies ok, GPS lock seems ok, but that flashing red sequence is bothering me. I see that in Phantom mode that can indicate low battery, which is not the case, but not sure if it's the same in NAZA mode. Tried two different batts. I'm just wondering if it has something to do with being in a restricted zone.
