Hi, I have an ongoing thread about my P2V only being able to connect to the Naza-M v2 assistant. I have tried all other versions of the assistant (p1, p2v, naza lite). I am therefore assuming my p2v has a naza-m v2 MC installed. All my firmware is up to date. When I power up the p2v i get the power on self test green and amber flashes and start up tone followed by 3 red light flashes with 3 beeps (which apparently according to the p2v manual version 1.8 is "not stationary or sensor bias too big") . No searching for gps lights ... no matter how long I leave it in an open area. Also the compass config does not start or at least not indicated by the correct light sequence by flicking s1 as per the instructions. I have run the IMU calibration 3 times and RC calibration succesfully .... it's made no change to the status of my p2v. To summarise ... it power on self tests, and then issues 3 red flashes and 3 beeps. then no more lights. The motors will power up and then the red lights stay lit for the duration the motors are on. Ive read the p2v manual version 1.8 from back to front ....... why aren't the lights indicating the p2v is searching for gps sats and why is flicking s1 not putting the p2v into compass config mode? Your help is greatly required. I'm losing hair fast. I have yet to fly this thing and dare not until I know the compass and GPS are operating. Thanks Phil.
