Hey,
I've recently purchased a Mini 3 Pro from amazon and setting up the drone was fine but when starting the drone for flight I got an error - which stayed during flight too.

(Downward vision sensor error. Contact DJI Support for assistance (Code: 1A0100C1) )

Landing seemed ok - albeit a bit slow. Lighting conditions were good and correct altitude reading. The error only appeared after the props were spinning.

i've tried refreshing the firmware, recalibrating the compass and IMU. When I tried recalibrating the vision sensors using DJI assistance 2 on my pc I noticed the top-down vision sensor was not showing an image on the lower left of the screen compared to the bottom-down sensor, I was unable to complete the calibration due to that. Seems like I have a faulty sensor on arrival.

Wondering if anyone knows this error code? Can't find it anywhere online or in manuals. And is this fault only fixable if I were to submit a service request? . .DAT log files are encrypted so unable to find out the root cause myself.

Thanks

Hi, calum. Thank you for reaching out. We're sorry for the unpleasant experience. The error means that there is an error with the right downward vision sensor. Since you already tried calibrating the vision sensor using DJI Assistant 2 and resulted in failed calibration, in this kind of situation, please consider sending the unit in for a proper diagnosis.  You may submit an online repair request through this link: {https://repair.dji.com/repair/index}.
