hi there everyone welcome to my channel i've had experience with my mavic 82 where the obstacle
avoidance is constantly beeping and i'm not able to fly forward or backwards and even though you
turn off the sensors it still keeps people so in this video i'll show you guys how i resolved it
first i'm going to show you guys how the issue displays itself so when you turn it on as you
can see on the screen in the background i have taken off now but there's clearly no
errors on the application you can check in the pre-flight check there's no errors whatsoever
and the optical woodens are detecting something on the front in the rear
but that's normal because i'm still taking off so there are obstacles in the front
and on the rear so taking off and taking and going up to a height of about plus minus 25 meters
you're going to see that it still detects obstacles i'm well
away from anything so not sure what's going on i'm not able to fly forward or backwards
turning around just make sure it's not the sun reflecting in the senses
still beeping dating something not sure
so if you try to fly forward because it picks up obstacles
forward and behind the app only shows behind but it is definitely straight forward as well
you can see there i can't fly forward or backwards so i'll change from bypass to
break and just see what's going to happen still a full stick forward backwards
drone just does not come to the spot
and the drone's in great condition there's nothing wrong with it it's physically perfect
so i've turned off the obstacle avoidance now and now i can fly forward
i can fly sideways i can fly backwards you can see there no problems but that beeping just goes on
so at the very least you're going to fly with optical warnings turn off
but you're going to have to turn off the volume on your phone that's the only solution to the beeping
still trying to move the drone just figure out what's going on and yeah nothing is working
so hopefully if you go to sport mode it will turn off obstacles right and the beeping should go away
let's do it as you can see it's still heavy
at first i thought it could be a bug that if you switch between sport mode and normal mode
it'll go away as you can see it's still beeping and yeah nothing nothing you can do about it
so now let me show you how to fix this okay so the issue is with the obstacle detection unfortunately
the beeping is no fix for that if you don't like the beeping you'll have to move your phone's audio
so first you need to download dji system 2 i'll link it below and you need to install it and run
it and connect your drone to your computer or your mac and luckily the app automatically detected
okay guys so once you're ready to download the software so you can
calibrate your drone you need to download dji assistant 2 for mavic
once you've found that just search that you'll find the download link
once you've got the link decide which one you need either for mac or a pc i am on a pc so
i'm going to select this one remember this is for the mavic 2 mavic 2 enterprise dji smart
controller mavic mini and mavic air 2. there are other dji assistants but they are for different
drones so please check the supported products before you click your download link if you click
your download page over here it will start to download automatically i'm going to click cancel
because i've already downloaded it so you're going to click cancel and you're going to download and
install the product once you've installed it you can open it and you're going to find dji for mavic
and it's going to pop up like this asking you if you would like to make a recording a whole
restart or for mavic mini in this case we are just going to close it because we don't need it
and you should get to this section over here once you're on this screen then you can plug in your
usbc cable i'm not sure you guys can see over here but a usbc cable that came with your mavic
air typically the cable that you use to charge the controller you're going to then plug it into the
drone itself so on the one side you're going to find your little port you're going to take
the cable and you're going to stick it in there once that's done it you can turn on your drone
and it's going to power up if you want to you can put your drone down but in this case i'm just
going to hold it like this okay so the idea is that it will automatically get detected the drone
is going to power up it's going to pick up the sd card you can ignore that all we need is we want it
to be detected by the system you're going to click on the mavic mini or mavic air 2 icon it's going
to go into the software area and if you need to upgrade your firmware you can do this in this case
firmware incompatibility detected some modules are currently well we'll need to use updates if
i want to i can just click confirm in this case let me click on firm and i'll show you what to do
this is most likely because my one battery has not been updated yet so it's going to go pretty quick
so it's not a huge update to do but as you can see dji assistant will check your software for you
and if you need to upgrade your firmware it will do it automatically for you as well
so pretty good um typically if i was in the field right now i would have powered up and it would
have said firmware inconsistency found would you like to update and then essentially i would have
had to update in the field wasting some battery so this is pretty useful to do if you've got
three or four batteries i really really recommend that you open um or link it up to dji system just
check because what you're going to do is you're going to put one battery in you're going to run
through the whole process you're going to take it out and then you put another battery in and
you'll start up again and if the battery needs a firmware update dji assistant will tell you so
so in this case we are just going to run through the software update and we can move on from there
as you can see this would have taken probably around about three four minutes in the field
that your drone would have just been idle there so pretty pretty important step to do
once it's done it's going to do the whole restart going to calibrate
camera is going to go up it's going to restart
and now we're almost ready to do the final step now remember we are doing this because we
are obstacle avoidance is going nuts and in my case you guys could have seen in the video that
i did not have any errors whatsoever there was no indication that something was wrong with my drone
i just turned it on and none of the sensors were working properly so now everything is
restarted the drone is connected everything is sorted this next step is very important
but very easy to do as well so just gonna click back the drone's gonna check the firmware again
everything is now perfect click on the calibration tab on the far left side once you've got that
you can click calibrate now but you can follow the instructions as well so make sure your code is
connected to the drone you'll click calibrate now and it's gonna pop up now what i like to
do is i like to hold the drone um by the back i like to hold it like this and then use my one
hand to just pivot on my other hand so while the drone is held with my two fingers just like this
nice and easy i can just use it to focus on the screen so you're going to move it closer
and there's going to be a little red icons on the screen or little markers to follow
once it's there you will just pivot the drone so that it matches all of the items these little
blue blocks you're going to follow so this blue little block just means that you need to track
the drone with that please do not move the drone just pivot it in the same spot so in this case
you can see again it asked me to move further back just follow the instructions on the screen
and pivot the drone accordingly now you're going to do it twice for each sensor so
if it asks you to move forward you go forward i'm just going to wait for it to catch up over here
in this case it seems it's going to fail all right there we go carries on
sometimes it lags a bit that's because it's taking some processing power
in my case it's taking a bit of a lot of power to process this bottom left corner
typically it doesn't need to do that but in my case it's now asking
for quite some time to be processing this bottom left corner there we go
don't be too scared just try and be calm and follow the instructions in this case it's very
very laggy on the bottom left side and there we go now it's nice and smooth so i think my bottom left
needed a bit more processing or configuration so i think it's a very good thing that i did
my controller as you can see it now says turn the drone to the bottom so follow the instructions now
if you take your blades off this will be a lot easier but just follow the instructions
on the screen and try and see you can get the angle correctly there we go i've got it correct
this is a bit difficult sometimes because you're going to have to try and view around your drone
but as you can see you can just follow the screen
just keep my bearings right here there we go it takes a bit of practice get used to this
but once you get the hang of it it's actually really easy to do you just it's like playing a
game just follow the marker on the screen with the drone and then moving around as you can see
i'm now going to the last step the mavic 2 pro for instance you would have had side sensors as well
but with the air 2 you only have front and rear so just follow the instructions there
sometimes you have to wait a little bit for it to move up nice and close
it's not detecting just wait for the softly to catch up
there we go it's easy it took a really long time to load so now
finally it's got this now a lot of guys would have moved the drone away just stay calm and wait for
it to catch up it can take a minute or two for it to just load on the pc or the mac that you're on
there we go sticking was always further
away now calibrating your sense is incredibly important because
not only does it help the accurate accuracy of your obstacle avoidance
but it also helps with the drone knowing how high it's off the ground or not
quite easy as you can see now you can just restart your drone actually you
can just turn it off you should be done now so you can just turn it off and you're done
now that all remains is for us to test and to make sure that it's working correctly the obstacle
avoidance has now been recalibrated so the beeping should be gone if there's no obstacles in front of
us meaning we should also be able to fly forward backwards left and right without any issues
what i'm going to do now is just change the obstacle buttons back on
go to break take off and see if everything is working properly now
it's optional behind me stuff the house but in front there's nothing and as you can see it's
stopped beeping finally issue has been resolved i'm able to use my drone again and fly around
and you can see nothing's beeping i'm able to move around no issues
just checking if the saints is not going to beep if i turn around maybe
the sun or anything like that you can see clearly
no issues whatsoever so let's just check bypass and see if that works as well
going forwards going backwards no problem
great stuff last i'm just going to switch over to bypass and see if i can flow
forward fly forward and backwards take a look at the speed at the bottom left and finally
i'm able to fly forward backwards switch bay the brake mode and my speed is fixed so yes i
can fly forward backwards you can bypass mother naturally gonna fly slower at lower altitudes
okay guys that's how i resolve the issue by calibrating the vision sensors
using dji assistant so if you guys have found this video useful
