Mavic 2 Pro .

EVERY time I start the drone I get
magnetic interference error - check App.

It is never solved by moving the aircraft ( and happens on places 100% sure without metal objects )
but it goes away after I recalibrate the compass.

Needless to say it is extremely annoying to recalibrate compass every time . i start .
( I fly somteimes the same location sometimes it is just a couple of kilometers way )


ANy suggetsions what could be wrong ?

Do you wear a (smart) watch? This can interfere with your compass. Your phone, your remote, everything electric you have in the area can and will interfere with the compass, so check out what you are wearing

Is it every time you start the drone or the first time at a new location.  The latter I would look at how you transport the drone,  for example any magnets in the bag?

It's not really because of magnetic interference. They just want you to do a compass calibration each time. They should change the error message.

If you dont need the gps coordinates, switch your IOS, if you are using one, into aircraft mode before takeoff, this has been known to affect the drone magnetically, but as ghost wolf states, smart devices often affect it too

How close are you to your car when taking off. I get that message sometime when launching close to my car.

Hello and good day Jann Lipka. I am sorry to know that you are having issues with your DJI Mavic 2 Pro and thank you for reaching out. Please check the location where you are calibrating the compass of the said drone. Let me please provide you additional requirements for proper compass calibration. In calibrating the compass of the said drone do not calibrate your compass where there is a chance of strong magnetic interference, such as magnetite, parking structures, or steel reinforcements underground. Do not carry ferromagnetic materials with you during calibration, such as keys or cellular phones. Do not calibrate beside large metal objects. Thank you.

Thanks for all suggestions .

Mag interference is regardless location -
Happens every day - sometimes ( seldom ) it will not happen when i change the location .
But always on a new day .

( yesterday I lifted on 6 different places maybe 40 km from each other ) didnt get mag interferance on 1 occasion .
All other lift offs- I need to dance. ( calibrate compass )

Its completely unrelated to real magnetic field- I'm not starting close to my car.
Also Its my 3rd drone - previous Mavic Pro- transported in the same way -  don't show this problem at all -
( starting from the same position )

I contacted support - as expected they dont read so they asked me to move starting position
( i do it like a maniac  to no help ) -  
After compass recalibration the message disapears- and I put the drone on the same spot-
and no problems ( untill next location ) battery change dont make mag intereference to re - appear.

I transport it in original Fly More bag with 3 batteries only - no magnets in the car trunk at all -

I have triple checked and have the latest firmware _
Support suggests now to reset the drone to factory setting ( using DJI assistent )
But i Think is just a waste of time . ....

It might well be worth refreshing the firmware on the aircraft (& factory reset), and perhaps a reinstall of DJI Go 4. It could be that something is misreporting a problem, a pointer towards a hardware fault (compass moving in aircraft, or bad connection ??? (speculation on my part)).

Ha, re-reading the original post I see the RC showed the magnetic interference error -- never mind -- hope you get it resolved.

Hi Guys.
Sometimes i wasnt even able to lift off without switching my phone to airplain mode. When you do, mag interf seems to be gone. Did calibration once when i get it, never since. Also the app kept falling without airplain mode. So every time im flying now i switching to airplain and have no issues what so ever. M2P

I have exactly the same problem...
99% of the time I have the "mag interference" message when turn on the drone, no mather where I am, I could be in the middle of nowhere and get the message.
I don´t wear any metal on me, no bracelets or necklace nor belts... I don´t even use a regular watch!
Sometimes I don´t even have the control with the cel phone near when turn on the drone (let´s say 20 meters away) and even that... I get the "mag interference" message...
Mavic 2 Pro with the latest firmware and the latest DJI go 4 (recently restored).

Today I went for a test fly to check the compass error and had that screen up all the time while taking off and flying. It changed from as low as a value of 5 to 37. Went up to 100m and made a large circle. If you could do the same I wonder what you would see. Would you see normal values or would the values be in the red? Perhaps there is a faulty magnetometer. Can you take off at all, or does this error stops you? This is just a guess as I am no expert on this. Just a suggestion.

I have recently updated latest updates and get the mag interf - check app every time I start up. Unable to fly at all because it won’t connect to my phone. I saw one comment from a DJI rep that said “make sure when u calibrated to not have any metal or cell phone in area “. How can you fly without a cell phone?
I also just realized that I just started using the new iPhone 12 Pro. Which uses MagSafe. Could this be my issue? And if so, will I not be able to use this phone to fly my mavic pro 2? Is there a fix for this?

Can a wheel chair or metal implants affect the magnetic interference

Steel objects can deflect the compass .... if it's close enough.
If you are launching from the ground 6ft or more, a wheelchair wouldn't have any effect.

But if it's a motorised chair, the magnets in the motor/s might have a stronger effect.

Yesterday I went taking off filming from short concrete abridge, which had steel railings on both side of it. Just enough that a car could pass it. I was worried that it might have interfered with the drones compass, so I checked this before I taking off and I could not see any difference on the readings. The compass reading looked good as normal. I was just about 1/2 a meter or closer to the steel railings. I was surprised that the steel railing did not have an effect on the drones compass. In my opinion it does not seam to be too sensitive at all to steel structures within this distance from the drone.

The railings will not be the problem, it is the steel reinforcing rods in the concrete that are a bigger problem. Particularly if you have the aircraft sitting on the concrete when you power it on.

Hi there Trigger2041. Thank you for the reply and for these inquiry. All metal objects and structures line wheel chair and metal implants can give out magnetic interference and might affect your flying experience. Have a safe and a happy flying always.

Hmmm, that is strange, as I did start the drone from the ground on the bridge and everything looked all right. Perhaps there are no reinforcement rods in that bridge. I will check this again next time I am there.

I have the same problem. I have two Mavic 2 Pro, with the same firmware on both. The second one was purchased a few months after the first one, and on every start it gives the message "magnetic interference - check app".  I have to calibrate the compass, then everything is OK and it flies fine.
The other drone never gives that message, only if I deliberately place it close to metal.
It seems a batch of M2Pro has this problem, I have not found a slolution, but it only takes a few seconds to do the calibration so I have not bothered.
When I check the sensors in Go4 the compass is yellow, after calibration it turns green. This has nothing to do with nearby metal objects.

A wheel chair perhaps. A metal implant no. I have had a total hip replacement and the primary metal used is titanium which is non-ferrous. If it had any magenetic properties I would have been torn to bits when I have had MRIs taken. That would have been ugly.

I have a friend, wheelchair bound and he has no problems like the rest of us.
