Hello everyone...


Today I received my new dji mini 2 (I sold my mavic mini to buy the mini 2), everything was correct, however, when I took off for the first time (after all the calibrations, firmware updates and checks), after I take off, an error appeared in red saying "vision sensor error. contact dji support for assistance", however everything was working correctly, for concern I decided to land the drone and turn it off and on again, and the control also... after reconnecting everything I took off again and the error didn't happen anymore... my question is: could it happen again? can my mini 2 be defective? Could this be something that could be a problem in the future? do i need to worry?


Thank you all

Yes you will need to either take it back to the store you bought it for replacement, or contact DJI. It is a defective unit and this error is caused by a faulty gimbal coaxial cable. The error only appears intermittently but it will not go away completely. Eventually, it will result in the drone being unable to take off due to not being able to clear the red Vision Sensor error message. You will also eventually notice a number of these error codes - 180016, 180017 and 180030, all relating to the Downward Vision Sensors and the fauly coaxial cable.

Thank you, I will contact the seller and the dji support for further clarification, I thought it was just something that appeared to be new and would not give again after starting to use ...

Yes have it replaced as soon as possible is my advice. The errors won't go away (although they do disappear for a few flights) and the faulty coaxial cable will eventually result in you being unable to fly at all.

Sometimes flying over dark surfaces can create this message or if they are dirty ... You said you are updated to the latest version?

hello .. will this calibration solve? as our friend said, this seems to be a factory problem on a coaxial cable

tried here now but it doesn't work for mini 2, after connecting to dji assistant 2, it only gives the option to export log ...

Please don't give out incorrect information as you are completely wrong. You can only calibrate the sensors on the Mini 1 via the assistant software. It cannot be done with the Mini 2!

Don't listen to the poster saying you can calibrate the sensors. This is ONLY possible with the Mini 1 and NOT the Mini 2 unfortunately. If you bought your Mini 2 from a store, I would recommend you take it back asap to have it replaced. If you bought it from DJI directly, they will replace it with a new unit under warranty.

Hello there The Foxy. I am sorry for the trouble this has caused and thank you for reaching out. Since you are having these error messages on your new DJI Mini 2 kindly please contact our DJI support team via http://www.dji.com/support to open a case and for a diagnosis on the said DJI Drone. We'll do our best to help you on this issue. Thank you and fly safe always.

I did one more flight today / yesterday 3 hours after the flight I did after the error appeared ... this second flight was also normal and without the error appearing, but as you said it must come randomly ... I already sent an email to dji support asking what should I do ... I bought it through the Chinese website Banggood ... exchanging this drone for another one (if necessary) will give me a tremendous headache ...

Yeah that is the really strange thing with these Downward Vision Sensor errors, it can go many many flights between the error messages appearing. The drone also flies, hovers and lands perfectly and seems absolutely normal. It will eventually, over the course of a few weeks though, get worse.

I wouldn't worry too much, you have done the right thing by getting in touch with DJI Support to open a ticket. They are great and will have it sorted for you in no time. Most likely DJI will ask to see the flight log where the error appeared and then email you a shipping label with a request for the drone to be sent in for analysis. You will then receive a brand new unit if it is determined to be a manufacturing fault (as opposed to a crashed unit for example).

Keep us updated how it goes.

Actually lil man they are the same sensors and you’re nobody’s boss on here either

They may be the same sensors, but only on the Mini 1 can they be calibrated via the DJI Assistant. Please keep up. I guess thats why you deleted your nonsensical post providing the incorrect advice lol.

The poster is clearly quite anxious about the issue they are experiencing and you added to that anxiety with your false information. If you don't know what you are talking about, which you clearly don't, perhaps butt out of future conversations. Otherwise you run the risk of making yourself sound even more ignorant.

What happened to your previous post where you insisted calibrating the sensors on the Mini 2 via DJI Assistant was possible? You obviously quickly scurried off with your tail between your legs and deleted it after realising how foolishly wrong you were lol.

Could you help me please? that day i got in touch with DJI support and they answered me asking for more information, however, when i answered with the information they had asked for, they are not answering anymore, until today i am waiting and nothing ... there is something you can do to help me ? the store that sold me the product is also waiting for that answer ... thanks

I have a screen recording of the message when it came up. I'll try again tomorrow because a restart fixed it

Glad I found this! I got my Dji Mini 2 for Christmas, It was working fine, then one day it started showing those errors, and I got a little worried. Found a Youtube video that seemed to give it a temporary fix, but it has just been getting worse, and now it did it when I was in the air. Was worried I did something wrong. Thanks for clarifying.

Hello,
I am having the same problem on my dji mini 2. The errors of vision sensors started appearing rarely at first. But after not using the drone for 3 months and turn it on and updated everything, the message keeps appearing makes it unable to fly. But the weird thing is that i never crashed my drone not even once. And the weirdest  is that after turn it on and off many times, the message disappeared twice and when I tried to fly the drone it got out of control but I was able to put it down with a minor injury in my hand. My question is does this out of control thing is related to the downward vision sensor or is it something else?
