Hi guys, does anyone experience this before? Before this I tried to do vehicle reboot through the QGroundControl software but nothing happened. The only thing that happened is rapid blinking of red and blue LED on the rear side of H520 near to the flight controller. While the LED's are blinking I cannot switch off the drone or do anything. Even after the red LED on the board disappear and the blue LED is solid blue, still I couldn't switch off the H520 with the power button. When I try to connect the drone with ST16, only camera is connected to the ST16 but not the drone which I can view the camera. But I cannot see GPS status, vehicle battery level or vehicle setting since the drone is not connected. Is there is any Reset button to reset the H520. Hope anybody can help me on this!
