Before leaving home to fly I check Everything on my drone before leaving.. A few days back I turned on the drone doing one of these pre checks and I received a forward vision sensor error. When I try to calibrate the sensors both sensor status images on assistant 2 We're completely black there was no image at all . I am confused how it wasn't flying and just by turning it on the sensor error popped up why would it do that? Also why am I unable to calibrate and what are the odds both forward sensors Go out at the exact same time?? Could it possibly be something other than a faulty forward vision sensor Even though both calibration status images on assistant 2 are blacked out with no image? Also the ambient light too low notification stays on constantly since the forward vision sensor error has popped up Regardless of how much or how little light there is... I apologize in advance for my my lack of knowledge I am still fairly new to drone flying
