I can't see D RTK flight log file when I swich on the RTK mode on my M600. I can see the DAT file when the normpal GPS mode is on but not when RTK mode is on. Air system RTK is connected with ground system well and the LED light is green and the datalink communication is also works fine. I can also see the base station and the air system reading displayed on DJI GO. Can anybody help me on this please?
