Hi Staff, regarding the mini 3 Pro and DJI RC, please could you let the techs know that there is an issue with the latest software...
The issue in question is that the RC indicator on the radar is not accurate, its out by about 5 degrees, that's after calibration of the compass, before it was about 30 degrees out. The next issue is that in the standard radar view with the drone on the outside rim of the radar, the incremental turns is in something like every 5 degrees, there is no precise sense of RC to drone alignment, whilst the dot changes to green Menai g alignment is OK, it's not spot on until the arrows align, now this is not possible due to both issues I have mentioned. This needs further attention, the mini 2 and my P4p are spot on, works 100% so it can be done, I just cannot understand why the techs would release it like that.~

EDIT:~Same goes for the map, that to jumps in large incremements, its bad enough that its nearly unusable

Another curious thing I noticed yesterday, When bringing the Mini3Pro back from a lengthy flight to land, the height indicator was registering a negative value even though it was still 10 metres or so above the Home Point.

Hi Bashy,

Guess DJI cannot do anything about the 5 degrees....it depends on the accurancy of the compass indication of the mobile device.

If i calibrate all my devices in this household (>10) than i see a variation in compass headings of about 20 degrees between them all.

Happily my most used device is fairly accurate, so using the radar indicator in the new way (drone icon on the outer ring) i know where my drone is in the air relative to me.

5 degrees doesn`t bother me, but i understand you bc it did work for your P4.

cheers

Hi,

Minus indication can be 'normal'  after a flight landing at the take off spot.
But minus indication flying at 10 meter above HP is imo too much.

Changes in air pressure do change the baro height indication;
1 millibar air pressure change = 25 feet = 8.5 meter.

Air pressure can change rapid fying close to upcoming bad weather.

I have seen the same behavior. And if I land, then start up again it is back to normal. Does yours eventually correct itself or do you have to land first?

Makes sense. Do you know how often it performs a baro check? Because if I hover a little while it still does not correct itself.

It's very common to see a difference of 10-20 ft between launch time and landing.

When its in the mode where the drone is on the outside it works how it should, a nice smooth movement around the radar although its still slightly off-kilter, surely they wouldn't use a compass that's not accurate for a device that needs a precise alignment, makes no sense whatsoever

I didnt notice, i spose i can look at the flight log, whats the method of retrieval from the RC, i assume its in the SD card?

Hi,

At start of a flight the baro height indicaction is set to zero, after land on as well.
This zero reference height is used during the flight.

Few meters + or - at land on is 'normal'.

uh, compass to position icon drone on the radar display is the mobile device or the RC compass.
Those compasses are not that accurate....

Plausible, yes. It was early morning with the sun just peeping over the hills. A 20+ minute flight could have seen a difference, especially flying to the top of the hill and back.

MTShipp_ Posted at 7-17 02:42

I haven't paid attention to that detail I'm afraid.  But yes, next time out it was reporting zero before take-off.

Bashy Posted at 7-17 03:25

It's saved in the RC, not on the SD card.

Your flight data is stored in the app, not on the SD card.
To check altitudes you just need to look at a few flights on the RC and advance to the end of a flight to see what finishing altitude was.

Thanks, guys, so easiest way is copy to card, I will do that when I go back, thbak again..

Part of the script I have written to create my pilot's logbook compares the height at take off to the height at the end of the log.
Most are, as expected, around 0 but there as quite a few in the 10's -20's ( metres) and a small few in the 100's............and suspect lol.
Where I have flown ±5m is physically possible through me changing take off and landing points i.e. walking up/down hill, but the ±10m+ ones can only be due to other factors. I do not remote land.
Just in case anyone is thinking of asking, I will not post the logs.

Hi,

Just a typical MINI2 example of height differences st landing, this time just 1 meter to high.
Notice that the last record the baro height is zero`d and this zero see on the screen as well.

cheers

Ah assuming you are correct then I used the last non zero value, it's a while since I wrote that bit and I am in the wrong computer to check.
Where are you getting the "MotorsOFF" from?

Have you managed to calibrate the RC compass with the latest FW? I tried but when I select calibration it just goes to done, does not let me do it.

I was able to the 1st time after it all updated from new, so everything was the latest, but since doing the 1st one, it will not let me do it again, stupid idea putting a stop to it just because IT thinks IT'S ok, with IT clearly isn't....

Hello there Bashy. Thank you for reaching out and for giving out these information. I will forward these information to the designated DJI Department for attention. Thank you.

Hi Stepehen, thank you, please can you add that the map is also the same, that to jumps in increments when turn the RC  so aligning is very difficult.

I am hoping Dji fixes this although it does not affect the flight of the drone I wonder if there might be an issue in the event of a warranty claim because it reads wrong in the logs

Well, yes and no, for me, it did affect the flight, i and to keep changing direct because i couldn't line it up correctly and i was only about 160m away but using the map as i was behind a tree (no los, shh)

For the range test, it came back shooting off to the right by a large margin, i wouldnt have know had i not opened the map to check, had i taken the battery down to the wire, i wouldnt have made it back, so its a good job i keep a little in reserve lol

So in that sense, it is affecting the flight and a safety issue to boot, is it a fly away when it veers off without you knowing?

If you put it that way then you are correct.

Same here Suren,  this last update broke the calibration feature.

Kind of a pain though. So far it's just the radar issues for me and drone banks right but using left stick to keep it going straight. IMU, RC calibration does not help. Flew perfect before I updated to lates FW.

Funny you mention the banking right,   mine would doing that today too,   I was going to calibrate the sticks again later.

Let me know if that fixes for you, I tried that but did not help. I should maybe try RC N1 and see if it still does that

An update was issued to the RC today, i have been out and tested it and whilst the direction is for the most part fixed, i say most part because its still about 5 degrees out for me, i did a calibration prior to taking off too.  

Also, the large increments are still there, it should turn smoothly on the radar and map. Thank you.

Looking at recent videos from very qualified reviewers it looks to me that the new update gives a very smooth rotation of the radar and the angles look spot on. Well done DJI

You couldn't help yourself, could you? You just had to contradict what i have said whilst being wrong in the process.

I have literally just come in from testing this and not watching videos and the issue that i am referring to is still there, the indicators turn with too large an increment therefore the indicators do not turn smoothly.

As seen in one of the videos you no doubt refer to, i have link to the time where its easier to grasp what i am referring, now, watch the birdie, (indicators), they turn in large increments, perhaps 20-30 per directional change.

Feeling foolish yet?

Glad they finally sorted it for all those like you who seemed to be having the issue. Mini is fine

That has been a thing on the recent aircraft firmwares.

I suspect, with the Mini 3, they are reducing the frequency for the telemetry in order to try to optimise signal strength and video feed, so the telemetry is not smooth like other models.  All part of the poor signal that will always plaque this model

Mini is alright and now that the Radar and Compus has been fixed for everyone a good result

Why do you keep saying that its fixed for everyone, clearly its not, even those on youtube are not fixed properly, in that one i posted above, you can clearly see that the icon does not move around like second hand on a clock, its more like an hour or even 2 hour hand at best.

Stop with this speaking for everyone, you do it all the time, we are individuals and can speak for ourselves
