The calibrate IMU function has not been removed!So we have updated to Inspire 1 Firmware v1.2.1.06 and 1.1.2 IOS app, which, unless I'm mistaken, but cant find it anywhere has done away with the IMU calibration function.
There is a known fault with the inspire that the camera periodically does not have the camera level, especially after a firmware update, and even when using the level gimbal function would be problematic and work for a few minutes at best. Recalibrating the IMU fixed this.
So if the calibration IMU function has now been removed - I'm at least hoping these other issues have now been resolved?
Any ideas?

It is still there.....
Try under 'Sensors'On IOS 1.1.2 it is not there... or am I going mad?! It used to be under advanced settings.
Any clues to its whereabouts much appreciated!
Try under 'Sensors'
Ok did Imu calibration compass mod bouncing between 1258.24 and 1300OK, in that case can I suggest you try something. Do another IMU calibration (obviously making sure its on a level vibration free surface etc and not disturbed in any way during its calibration) but do the calibration immediately you turn on the inspire so the IMU/flight controller is cold.
As soon as the gimbal has done its auto calibrate bit and your lady has said "welcome to your aircraft" etc go straight in and calibrate the IMU.
Give that a try.

You are wrong. The compass should be calibrated every time you go flying - before the first flight in each location. This is the best way to ensure it does not do silly things. Everytime you put the Inspire in the car or near anything magnetic or electric there will be a risk that the compass will be affected.Correct me if I'm wrong, but..........
Guys this update only updated the batteries, so there is no need to re-calibrate the compass, nothing was updated but the batteries.
Hmmm... I beg to differ but that's just my working practice.You are wrong. The compass should be calibrated every time you go flying - before the first flight in each location.

I trust your judgement Ed, so where do you calibrate your bird?, as I look for an open rural field with none of the usual suspects that may interfere with the process. You have more than likely posted this before but as I believe most fly-always are due to lack of diligence in compass calibration, can I get you to comment once again?Hmmm... I beg to differ but that's just my working practice.
I DO calibrate after a firmware update (including this one) but I NEVER calibrate the compass out in the field (my reasoning behind this is well documented on these forums so I will not go into it again).
I will say, I have been building and flying multirotors for around three years now and I have never calibrated my compass out in the field (never had to). Also, have never had a problem in flight, any TBE or strange flight behavior at any time.
Have a look at post #83 here, that should outline my philosophy.I trust your judgement Ed, so where do you calibrate your bird?, as I look for an open rural field with none of the usual suspects that may interfere with the process.

Thank you Ed. I have post #83 locked away.Have a look at post #83 here, that should outline my philosophy.

People have to make up their own minds but this has been my goto flying practice for as long as I have been flying semi autonomous multi rotors.
Just make sure you have a known good calibration and you should be good to go.Thank you Ed. I have post #83 locked away.
Good stuff Ed, it's in my routine now.Just make sure you have a known good calibration and you should be good to go.
A good way to check if you have a good cal is:
Pick a spot where you think you should get a good compass calibration away from anything metallic etc.
Calibrate and look for that magic 1500 number (or pretty close to it)
Power off the Inspire, pick it up and walk 30 or 40 feet in any direction.
Power it up again and check your mod values again.
If they are widely different then you probably had a bad cal.
If they are pretty much the same do the turn off and walk 40 feet (in a completely different direction/spot) and turn on again. If you are still in that 1500 zone you have a good calibration for your declination and you should not need to touch it again unless the app tells you you have a compass error or you travel a long way.
Always and I mean ALWAYS check your mod values though before you fly/take off. If any of them are out of spec don't fly.

@Scotflieger, if you do the 3 corner walk with the bird at the new location as the editor says & the IMU gives you the magic +/- 1500 then your compass hasn't been affected by your car etc. That's science I can believe.I'll trust the EDITOR on this one, you DID calibrate after this battery only update?
In theory (and looking at the log files) yes it was only the batteries that got the update but......... We are talking about DJI here so its possible that something else got updated with no audit trail to it! I always like to be overly cautious on updates so my regime is to do IMU, Compass and Stick calibration after every oneCorrect me if I'm wrong, but..........
Guys this update only updated the batteries, so there is no need to re-calibrate the compass, nothing was updated but the batteries.
