    "Ultrasonic Module Error" since updating to 01.03.0400

    That is absolutely shocking, to be honest I would be inclined to return it for a replacement if your original drone was in perfect condition. DJIs repair process is shambolic and its seems they are run by a bunch of amateurs. Each and every time, they've sent my drone back in a battered shabby...

    "Ultrasonic Module Error" since updating to 01.03.0400

    That's unfortunate. :( I'll just have to get in touch with DJI and see what they can do and if necessary will have to keep sending it back to them until they get the problem sorted.

    "Ultrasonic Module Error" since updating to 01.03.0400

    They replaced the drone with a refurb unit containing a new serial number, even though I received a quote for a replacement system board (covered by warranty), which I find incredibly sly as they make it look as though they're swapping out a component on your drone, which is simply untrue. I...

    "Ultrasonic Module Error" since updating to 01.03.0400

    Hi all, Just to say that I received my drone yesterday good news is that the ultrasonic issue is now fixed and as we suspected, this was definitely a hardware fault. The ultrasonic pulses can be clearly heard, even without a microphone. The bad news, is as I suspected would happen, the image...

    From this point it took another 3 days to have my replacement sent out. Mine has touched back down in the UK and is currently in Tamworth so I should hopefully get it tomorrow with a bit of luck.

    Sorry to hear that. :( Let us know how you get on with the return/replacement.

    "Ultrasonic Module Error" since updating to 01.03.0400

    At this point, it's difficult to tell, although the small number of people suffering this issue compared to what (seemingly) are a majority of happy people who are not suffering the issue. I'm still not convinced, at least in my case, that this is a software issue. I guess once I receive the...

    I really hope so! Unfortunately we're dealing with DJI, so am not going to hold much hope. :(

    I didn't want the risk of the replacement having other issues, such as uneven focus issues, yellow spot in the middle of the image etc. Mine had been perfect in this regard, the image was extremely sharp and I had been experiencing no issues until the ultrasonic sensor problem came along. I...

    "Ultrasonic Module Error" since updating to 01.03.0400

    This happened to me. It took 3 days for them to acknowledge that they had received my parcel. :( Mine has apparently been repaired (aka they've made it look as though they've repaired it but in fact sent me another drone with a different serial number) and it is now on its way back to me. I...

    Good luck, hopefully everything will be sorted. I received an email from them earlier today to state that my drone has been received, the repair tracking is now at 'Conducting Damage Assessment'.

    "Ultrasonic Module Error" since updating to 01.03.0400

    You won't get an error with the old firmware as DJI didn't add any measures to check for ultrasonic module functionality. The only way you'd know if it was working is by making an audio recording next to the drone, where you'd expect to pick up the ultrasonic pulses against the microphone in the...

    I did exactly the same, and it never made an iota of difference. Fortunately, I was sent a pre-paid UPS label by DJI when they opened a new case for me, so no shipping costs were involved. My drone was delivered to DJI in the Netherlands on Friday, so now just waiting to hear from them.

    "Ultrasonic Module Error" since updating to 01.03.0400

    This is certainly a possibility, mine was shipped from Apple on the 29/11/2016, however this could have been from the same batch. It seems strange how we're only a handful of people reporting this issue, for the most part everyone else seems happy. I was wondering this too, but I have tried...

    "Ultrasonic Module Error" since updating to 01.03.0400

    Oh that's not good. Have you tried an audio recording of the drone with your phone whilst it's idle? If you hear a knocking/clicking sound then the US sensor is operating. I think in our cases, the US module has either gone faulty, or the newest update has somehow permanently disabled the...
