Latest Mavic Pro Firmware is

Firmware : v01.04.0100


WARNING

You can not downgrade from V01.04.0100 to previous versions via 3rd party methods, Once you update to this version you will be stuck there unless further developments happen from the OG team.

Downgrades

As it stands today DJI have removed official methods of downgrading firmware from both Assistant 2 and DJI Go, there are 3rd party methods available.

More info can be found here on Quad808 Blog

IMPORTANT CHANGES TO V01.03.0800/1000 FIRMWARE ONWARDS




DJI Have Introduced a new safety feature that restricts flight height and distance when flying with out a device or app connected to the Mavic, while this probably will not affect many there is some things you should be aware of.

More specific info on this here explaining exactly how it works.


DJI Mavic FW ChangesV01.03. 0800 (8 min 12 sec)



CURRENT KNOWN ISSUES



3rd PARTY APP ISSUES WITH FIRMWARE - RESOLVED

There was an issue introduced with the Magic Pro FW v01.03.0500 that could cause erratic behaviour when used with 3rd party apps such as Autopilot and Litchi, All the 3rd part app providers sent out a warning to say to downgrade to v01.03.0400 if you wanted to continue to use them, This issue was carried over in to v01.03.0550 as well.

SOLUTION

Firmware version V01.03.0600 Resolves this issue for the Mavic, It is strongly recommended to update to this version.



OBJECT AVOIDANCE AND SUN - IMPORTANT WARNING

Its become apparent some people flying in P mode with object avoidance on have notice the craft stops and pic up the sun up an an object, this only happens with a low sun when the craft is facing directly into it.

More worrying this behaviour has been seen to happen in return to home as well when the sun is in the path to the take off location, instead of returning to home the craft rotate to face the home point and just sits there, some times it will keep gaining altitude to try and get passed what it believed is an object, eventually when the battery reaches critical landing the craft will then auto land where it was.

It is very possible this could result in a loss of craft.

SOLUTION

As a matter of caution I would strongly advise to disable object avoidance if your flying in low sun enviroments and in locations you can not see or control the craft, setting your RTH altitude well above all surrounding objects is critical.

Hopefully DJI will optimise this further in firmware but report of this happening have dropped to almost zero.



COMPASS ERRORS - SPORT MODE

A number of users have reported regular compass errors, magnetic interference errors , most of these appears to centre around sport mode and compass 1 when if fast forward flight

SOLUTION

The compass errors may be a result of a hardware issue with the compass its self, users have had this resolved by sending into DJI for repair.

Another believe is the rear motor wires are run loose and close to the rear compass module, in later production DJI have changed the wire location and twisted them tighter, some users have found by stripping the arm and adjusting the wiring location and twisting them this resolves the issue.

NOTE all Mavic's are still under warranty and any modifications would render that warranty void.



JELLOW OR GIMBAL JITTER- POOR PERFORMANCE IN COLD CONDITIONS -UPDATED

Its been noticed that there seems to be a number of issue with poor camera/gimbal performance especially in colder conditions, people are noticing rolling shutter, gimbal jitter ect.

SOLUTION

DJI have release Mavic Fw 1.03.0200 that states it improves gimbal performance in cold conditions but if your still getting poor gimbal performance, jitter or twitching it would need to go into DJI for repair.



POOR FOCUS

A number of users have reported bad focus regardless of correctly focusing the lens, If no matter what you do and how you ficus you always find the image soft there may be a camera issue and would contact DJI Support to arrange repair.

Users who sent their units in found their repayment or repaired units were 100% afterwards so there does appear to be a hardware issue with some craft .


BOTTOM USB NOT WORKING

After installing fw some people have noted the bottom USB port has stopped working, DJI have added a change so that it defaults to the side USB port over the bottom one, to use the bottom one you must completely remove the cable from the side port then the bottom one will become active.



MECH ERROR & RC STICKS NOT CENTRING - RESOLVED

A number of users have reported their sticks not showing centre causing the aircraft to move with no input, there have been a very small number of reports of the stick failing to respond as well.

After performing RC calibration they are then presented with MECH ERR on screen at startup, this appears to be because its detected the sticks are outside of the normal centre dead band, If you look at the RC calibration screen the sticks should be showing centre with 0% on all 4 directions, DO NOT attempts to perform an RC calibration If your sticks are showing fine and centre as this could cause the error to happen, it appears to be an issues with the RC calibration process its self, the Mavic uses Hall Affect sensors and magnets to detect movements so its unlikely its a hardware issues, hopefully its an issues with the calibration process and a firmware update should resolve this


RESOLUTION

This was resolved with v01.02.0900 fw.

Common Mavic Pro Questions and Answers


Whats in the box






Camera Focusing

Unlike the other camera drones DJI have fitted the Mavic with an Auto Focus lens and this means its able to focus on close and distant objects depending on what your filming.This is a pretty big feature as the only other product to do this was the the professional DJI X5 & Z3 Series of cameras.
The Mavic is able to focus from 0.5m to infinity and allows you to set it up to get the best possible image, this means the user must focus the camera on the subject they are filming at the start otherwise you may get soft out of focus footage.

To focus the camera you just tap on the object on the screen that you want in focus, just like before you taped to set exposure you now tap to set focus, exposure metering can still be done as before by switching between focus and exposure control.
DJI Blade Strike has posted a video demonstrating this in the below post

https://www.rcgroups.com/forums/show...6#post35848275



Controller & FPV Live Feed


The Mavic Pro uses a completely new smaller controller, this uses the new OcuSync wireless system and is not compatible with the older Lightbridge products such as the inspire 1 or Phantom 3 or 4 remote controller.

The controller has a number of USB ports but no HDMI output, the link cable from the controller to the smart device can be changed to suite Lightening,Micro USB, USB Type C and Reverse Micro USB devices.

The bottom of the controller opens out to hold a smart device up to a thickness of 6.5-8.5mm and max length of 160mm, To use a large device you would need a longer USB cable and something to hold the device on like a tripod or custom bracket.


Live FPV feed uses OcuSync, this is a completely new digital encrypted link transmitted on 2.4hgz, OcuSync can transmit video at 720p and 1080p and is low latency, 5ms for rc commands, 10ms for video data and 130ms for videos and supports a maximum download speed of 40Mb/s .

1080P Feed is only available in 1080P recording mode, in 4K the live feed is limited to 720p 30fps

OcuSync also supports wireless connections to multiple devices and you can connect the DJI Goggles, remote controller and Mavic wirelessly at the same time, you can also add an additional remote, so that you can control the Mavic with two remotes or share FPV videos.


Power Output FCC:≤26 dBm up to 7km - CE ≤20 up to 4km Range




Flight Control System & Redundancy


The Mavic uses a flight control systems completely designed by DJI,This includes 5 cameras, GPS and GLONASS, 2 ultrasonic range finders,redundant IMU and Compass sensors and 24 powerful computing cores.

The Craft uses GPS for position hold and can receive to both GPS and GLONASS positioning data, its flight controller has duel IMU and compass sensors to ensure the flight controller is getting the best possible data at all times.
It has duel downward facing came and duel ultrasonic sensors than allow the craft to see the ground and keep extremely accurate position and height regardless of GPS coverage, these sensors also allow the craft to take pictures of the take off location so when landing it can compare and set down to with in 1cm of take off position.

At the front you have two optical sensors for Object Avoidance, these cameras together with the bottom ones and ultrasonic sensors are creating a 3D picture of the environment around the craft allowing it to see obstacles unto 15 meters in front of it.


Flight Modes

The Mavic uses P GPS mode and Sport Mode, In P Mode all sensors are available such as object avoidance, VPS, GPS, Baro and compass, In Sport mode Object Avoidance is disabled but all the other sensors are still active.

The Mavic does not have a user selectable ATTI mode but it will enter it should bad GPS or compass data be detected. Just like the P4 its able to detect sensor issues and discount them to prevent poor flight behavioure



FPV Goggles

You can not use traditional FPV goggles as such as there is no 5.8ghz, HDMI or other video output. If you wanted to use FPV goggles Its recommended to use DJI own goggles that use OcuSync to transfer wirelessly directly. Alternatively you could use your smartphone in a headset or use a tablet with a HDMI out like the Nvidia Shield and feed that to capable goggles like the Headplay HD, FS V3 or Dom V2 or any other HDMI input, whilst the Headplay should look OK they are only 720P native, Any of the current Fatshark or other FPV goggles that don't have native 1080P or even 720P screens will not yield good results.

The DJI FPV Goggles - SEE THE WORLD LIKE A BIRD

DJI Goggles makes flying totally immersive, putting two lifelike 1920 × 1080p LTPS displays with a wide 85° angle of view in front of your eyes for a true bird’s eye look at the world around you. Built-in OcuSync delivers a 1080p video stream and, because it connects directly to the Mavic and not through a cable or a Wi-Fi link to the controller, a super low latency.

These are currently not available and i will post more info as it comes



Battery Charging

The Mavic battery is a 3S 3830mah DJI Smart battery, this battery can not be charged by a normal Lipo charger, this is because DJI smart batteries contain the charge, Balance and monitoring circuit within the pack, to charge it requires a fixed voltage current limited output psu not a LIPO charger, the battery also has a propriety connector. The DJI Supplied adapter is believed to be 50w will charge the Mavic battery in about 80 minutes from flat.

DJI have also released a charging hub for the Mavic Pro




This is designed for use with the Mavic Intelligent Flight Battery,when used with the Mavic Battery Charger, it can charge up to four batteries in sequence according to their power levels, from high to low, Its been confirmed there will be a parallel charging hub released in the future that can be paired with the 100w adapter from the phantom 4 allowing you to charge the batteries in parallel.


Propellers


The Mavic uses custom 8330 Carbon Fibre Reinforced Quick-release Folding Propellers, You can not fit normal propellers to the motors as they have a custom mount.

Frequently Asked Questions

Q: What it the focus all about ?

A: DJI have fitted the magic with a tap to focus lens, you can tap on an object on the screen and set the focus from 0.5m to Infinity.

Q: Is this an Auto focus ?

A: No its not a tracking focus you must click on an object onscreen to set the focus, you then can lock.

Q: Can i use normal FPV Goggles ?

A: Not as such,, The Mavic does not have HDMI or analogue outputs, the FPV feed is encrypted digital link and is not compatible with 5.8ghz traditional fpv. You could use a smart device with a HDMI output like the Nvidia Shield but as for how well this will work is unknown.

The magic does not have the option to add HDMI like the P3/P4

Q: Does it have ATTI Mode ?

A: Yes however this is not user selectable currently, the card can choose to enter it should it have bad comp add or GPS data however the user can not currently select it.

Q: Does Object Avoidance work in all modes ?

A No, Object Avoidance does not work in sport mode due to the angle of the craft for fast flight.

Q: Does Object Avoidance work RTH ?

A: Yes if it has been enabled in the menu before hand , however it is unknown if this is the case for sport mode as its normal disabled, its advised to set your RTH height to be higher than any surrounding object.

Q: IS the FPV Feed 1080P?

A: Yes however only in 1080P and below recording modes, in 4K live feed is limited to 720P

Q: Can i use a Phantom or Inspire controller on the Mavic ?

A: No the magic uses the new OcuSync system that it not compatible with Lightbrige or Lightbridge 2.

Q: Can I use a normal Lipo battery in the Mavic ?

A: No DJI uses proprietary smart batteries on their products

Q: Can i charge the battery with a Lipo charger ?

A: No the DJI smart battery has the charge circuit and balancing circuit built in, the provided charger is just an fixed voltage current limited switch mode PSU.

Thread OP
As we are heading towards some of initial orders landing with folks I have put together the usual tips for people for when you receive you new craft , upon receiving your Mavic you want to do number of things before you fly to ensure you get the best experience.

Important Note: Before turning on the aircraft always make sure you have removed the gimbal clamp and it's free to move around unobstructed.

1: Firmware and App

Download the latest version of DJI Go to your smart device, you need DJI Go V3.0 onwards to support the Mavic.

The Mavic will be shipped with firmware already installed but this may not be the latest, Its highly recomended that you update your craft before you fly, read the DJI update release notes and understand what the update should do and how to perform it before starting.

The Mavic firmware update is performed via the Go App or DJI Assistant 2 on PC or Mac, the Go App is done wirelessly and you will update both the craft and Remote controller this way, DJI have produced a video showing this process and I have link it on my blog page for the Mavic here

https://www.rcgroups.com/forums/show....php?t=2748810

If you have additional batteries you may need to update these as well before you fly, to do this just turn the craft on with each battery in and it will go through the update process again for that battery if required.


2: IMU Calibration


The Mavic's IMU has been pre calibrated by DJI at the factory and you should not need to recalibrate out the box unless prompted to by the Go app, DJI Dr Turbo states

The IMU was calibrated carefully in the factory under controlled environment so you do not need to warm up the IMU before each take off. Once you calibrate your mavic at home, you lost such features

The calibration process has changed on the Mavic compared to the previous DJI models and is now done by rotating the aircraft through 5 axis while following the on screen prompts, If you do need to calibrate I would still advice doing this on a perfectly level surface as well as making sure the aircraft is a cold as possible, this help reduce warmup times at the start so make sure the Mavic has been turned off for a period of time, I personally let it chill on the patio for 20 minutes in the evening as this should be enough to ensure you don't get excessive warm up times.

DJI have released a video showing how to perform this, Again this is listed on my blog above.


3:Gimbal Calibration
Once that's done perform a gimbal calibration on the same level surface.


4: Remote Controller Calibration
Set your desired stick mode and calibrate the remote controller sticks and buttons to make sure they perform as they should and endpoint as set.


5: Vision System - Object Avoidance & VPS
The Vision systems come pre calibrated from the factory and you should not need to do anything with this out the box, however if you get an error you can perform a quick calibration in the field but its recommended to perform a full vision system calibration via the DJI Assistant 2 Application.


First flight.

1: Read all the DJI Mavic manuals a few times as there is a huge amount of info in them and its easy to miss something important, i actually advise printing the manual out and having a copy with you, you need to fully understand the flight modes and how the craft behaves in RTH especially with object avoidance, this can make the difference a safe return or a lost craft should the unforeseen happen and you run into trouble.

2: You need to calibrate the compass before your first flight, make sure you do this in a wide open space well away from anything that may contain metal such as reinforced concrete, also make sure there is no metal on your person, Apple Watch and other personal smart devices can have a massive affect on the crafts compass so when you calibrate or handle the craft keep these devices well away.

You do not need to calibrate the compass before every flight, once a successful calibration is done you only need to calibrate again if you travel over 100+ miles or the app prompts you, more on this below. After calibrating the compass I would advise to check the RTH height setting in the go app, make sure its set heigh enough to clear any building or trees, while object avoidance its active in RTH in P-GPS do not rely on this and always set RTH heights accordingly.

Errors

Understand what the aircraft is telling you and NEVER ignore any errors, IMU, compass or battery errors can be serious, if it happens on the ground before you take off stop, reboot everything and try again, If you receive a compass error at a new location that's not that far <50 miles from the last location you calibrated it make sure the area is clear of metal, underground structures or cables, if your taking off from concrete it's possible it's reinforced and this is interfering with the compass, try moving to an new location +40m away and try again before you recalibrate.

Compass errors specifically - Apple Watch and other personal smart devices can have a massive affect on the crafts compass so when you calibrate or handle the craft keep these well away and off your person.

Take it Slow

Take it easy for your first few flights until you understand what the craft is doing and how it behaves vs how you expect it to behave as these can be very different, avoid flying over water or tight spaces and give your self plenty of open space to check the craft is working correctly and you understand its controls and the onscreen data.

IMPORTANT NOTE: Object Avoidance and VPS are not active in Sport Mode and as such make sure you set RTH height accordingly to avoid any building or trees, your aircraft will not stop or avoid objects in Sport mode.

IMPORTANT NOTE 2: CSC has changed compared to the Phantom 3 and Inspire 1 so familiarised your self with this new method.

Battery

The DJI smart battery contains builtin charge and balancing circuit, it is also capable of self discharging if left fully charge to storage level below 65%, this can be set in DJI Go to start between 1 and 10 days after charging, Setting this to 3 days is a good mid point.

Take it easy on any brand new batteries, they can take a number of cycles to realise full capacity and flight time and try not to fully discharge a new pack for the first few cycles, ideally don't discharge a new pack below 50% for the first 10 cycles.

Try not to fly a partly charged pack and only take off with a fully charged battery when ever you can, if you stop flying do not use the pack again for another flight, further to this only fly a fresh fully charged battery so fly with in 24 hours of charging the battery, if the battery has been sitting for over 24 hours discharge it to below 90% then charge it fully before you fly.

In closer weather keep a charged battery warm before flight, cold weather can have an averse affect on the battery and its performance so try to keep the pack warm between charging and getting to the fly site, battery temp should ideally be between 20-30c for take off,you may not be able to arm the motors if its below 15c, if between 15-20c take off and just hover for a bit for the pack temperature to rise above 20c, this can be checked in the battery information scree in DJI Go.

My DJI Mavic Info Blog is located here on RCG

The tips and the information above is a collective of information taken from years of use by users and DJI support reps.

Specifically Blade Strike has come up with almost all of the information and best practices and should be thanks and credited for that, I have purely collated that information and tweaked it towards the Mavic.

Thanks should go to

Blade Strike, Dr Turbo, Tahoe Ed as well as all of the users who have worked out this stuff over the years

Thank You

The Mavic will be my first DJI product after about 10 years in RC. Including about four in multicopters. I've been scouring the forums for best practices and now the official Mavic manuals, too. So I appreciate your putting this summary together.

Where can you find the info for what FW your Mavic is on?
Also for the controller and battery?
Do you have to hook it up to the computer and use Assistant?
