Please can anyone help, i am new to the dji multirotors and can't seem to find a few hard to find answers if been searching the net all over until i came upon this forum. First, compass calibration, in the assistand software there is a setting called advanced calibration, does that mean i can just let the dji sit on the ground while conneted to the pc software activating the advanced calibration in the software, then wait for 10-15 minutes according to the software and do nothing and after that it will be calibrated ? Sorry if it may sound like a strange question but i could not get past the first step yet as it said something was hot and i needed it to cool down before trying again and i m not at my dji to try it again tight nw, Or do i still need to do the various 360 degree movements ? Thenmost importantly, when armed i get 2 green flashes and 3 red flashes, for the life of me i could not get answers on any forum for those specific light codes, please can anyone tell me what it means, it does arm and it does spin up though.Doe the lights indicate a calibration problemor just a gps lock issue ? i was inside a building when i tried it.
