I recently purchased the DJI Naza V2 with GPS compass, but I can't get the system to get past the flashing yellow LED and allow me to arm the motors.
The system is mounted on a clone F550 frame, using Turnigy SK series (Areodrive) 2830 1130kv motors and Turnigy Plush 30A ESCs, also I'm using 35mhz radio (Futaba PCM), but I have tried using 2.4ghz (DSM2).
I have followed the setup to the letter using the v2.4 assistant software, making sure the RX calibration is correct with all controls at zero, and the three position selection switch highlighting the 3 x modes (had to adjust end points at both ends of the travel to highlight GPS & Manual).
The compass calibration completes sucessfully, but then just returns to the flashing yellow LED (LED pulses maybe 2 or 3 flashes very quickly every second or so), and does not change regardless of which mode I select.
I had seen on some other forums, that the Naza needed some warm up time, but after leaving it running for one and a half hours yesterday, still no change, I have also tried powering the PMU first before the ESCs, as I read this solved an arming issue, but this was on the V1 so possibly a pointless check.
I'm new to DJI products but not multi-rotors, so I'm fairly sure I haven't made any really obvious errors, but if anyone can help it would be much appreciated.
