DJI released new firmware v2.1 for A2!

[DJI Innovations]

What is new?

Firmware:

1.Enhanced performance of A2 flight control system in data loss situations that are caused by abnormal communications.
2.Optimized control performance, if the command of Yaw control stick is zero, the command variation of Elevator, Roll and Throttle will not change the aircraft attitude around Yaw.
3.Optimized IOC function and POI algorithm to improve user experience.
4.Optimized communication protocol.
5.Support to upgrade A2 GPS Module.
6.Fixed the attitude jitters during Failsafe and Go Home.

Assistant Software:

1.Added RC status display.
2.Assistant Software released with support for Mac OS X 10.6(Lion)or above. Assistant software usages on Mac and Windows are exactly the same.

User Manual:

1.Added installation and usage instructions for A2 Assistant Software on Mac OS X.
2.Added Failsafe settings for traditional receiver users.
3.Added RC status description.
4.Revised the control mode introduction.
5.Added trouble shooting list of motors start failures.
6.Added a note that if the second level low voltage alerts occur when the aircraft is during Failsafe and Go Home process or the aircraft is controlled by Ground Station, the aircraft will descend automatically.
7.Revised the recording conditions in IOC function.
8.Added a system error LED indicator shown in continuous 4 red blinks.
9.Revised the attitude status LED indicator, there is no blinks if the attitude status is good and continuous 3 white blinks if bad.
10.Added the note that when using with A2, the firmware of iOSD Mark II should be V3.0 or above and OSD Viewer should be V4.0 or above.

Notes for Upgrade:

1.For safety reasons, do not use the power battery for power supply during firmware upgrade. Reconfigure all parameters in the Assistant Software after firmware upgrade.
2.When using the A2 flight control system firmware version V2.1, the firmware of other DJI products used in conjunction must be matched with the requirements in the table below.
3.When launching for the first time on Mac OS X, please open the Assistant Software in the Finder. After the first successful launch,the application can be launched by double-clicking the A2 icon in the Finder or using Launchpad.
4.Please download the application installer in DMG format from the download page of A2 on the DJI website.
5.The Assistant Software for Windows and Mac OS X will be updated simultaneously in the future.

Are you new to DJI!!!

This was released months ago!

I will leave it for a reply then delete this thread as a duplicate.

It seems some users are not applying all updaes and it's causing issues.

A2 2.1 Upgrade - Please upgrade all modules!

Dave please don't remove. As Blade Strike mentioned, there have been issues with users not upgrading all modules. The above has the current firmware for each component. We are requesting that users check their firmware in Assistant. Thank you and I do agree I was confused as well. That is why I inquired to DJI HQ.

I'm not a DJI user but watched the video just out of curiosity. I did find it contradictive that the video shows powering up the A2 with the Lipo battery but in the instructions it says:

Notes for Upgrade:

1.For safety reasons, do not use the power battery for power supply during firmware upgrade.


So what is the correct way?

USB power or a 5v rx pack

they state that so that you won't be tempted to use a flight pack during the firmware update process. the power mgmt. unit can get the system up and running with as little as a 2S pack which would be a much better choice in the event that the firmware update process goes awry and causes props to start spinning.

i looked at that a little crooked the first time also but it kinda/sorta makes sense to point it out for safety reasons.

I posted this in another thread, but thought I would also post here to see if anyone else has had the experience.

Yesterday when I was out I had just done csc and the motors were spinning about 10% on the ground, then I hit the go home button by mistake, and it shot up into the air to attempt to go home (very dangerous).
Surely this should not happen if you are on the ground with idling motors.
Today I changed it to hover for the go home switch, and tried it, and again it went to 20 meters and wanted to come home.
Would be nice if anyone else could try this to see if its not just me.

Once you issue a csc the copter is armed. You issued a failsafe and it did what you asked it to do. That would be like complaining that a gun fired after you took it off of safety and accidently pulled the trigger?!

Which is why I tried to turn it off, and changed it to hover...but it still wanted to go up 20m and go home. (This is my first few days with the A2)
Makes you think what would happen in that situation then if it was on the ground and you had it set to just go home.
It is very easy to flick a switch by mistake.

DJI's advanced features really shouldn't be set up until the helicopter has been flown and the user is very comfortable with how all of the basic functions are working. At that point it's best to review how each advanced function works, what's required for them to function, and then to only do so one feature at a time. Once the motors are running there aren't any more thresholds to cross before the flight controller will use what you've given it to do its job. idle to you is a running motor to the flight controller, tell it to return home and it will return home.

Ugly things, that's what. Been there, (different FC). Radio system glitched due to what later proved to be a known bug, receiver issued a F/S, and away she went. Only problem was, it wasn't flying yet! Took days to repair my 1000.

Upgrading the GPS Module firmware of A2 flight controller

After communicating with existing A2 users, we find that there are many users do not update the GPS Module to the latest 20.1.9.1 firmware when upgrading the A2 firmware v2.1.

The new GPS firmware includes two part, firmware for GPS Pro and firmware for GPS Module. The GPS PRO module communicates with other modules and the GPS Module tracks location.

This new firmware for GPS Module optimizes the algorithm of calculating GPS positioning information and improves the performance of the GPS when flying in bad weather. It will also help to prevent cases such as lost GPS signal that is often caused by numerous environmental factors. This new firmware will greatly improve the performance and safety of the A2 system.

DJI suggests that all A2 users should get their systems updated, especially the GPS Module to the latest 20.1.9.1 firmware.

Please watch the A2 firmware upgrade tutorial video below.

Ive upgraded everything correctly.Can Dji tell me why I get a terrible drift in gps hold when applying any rudder inputs. Even small rudder inputs make the craft drift out of control then sometines it slowly comes back to position. I emailed Dji for 2months no resolution to theproblem! Very poor support! Now I will not be able to film my bros ashes being spread to the ocean this coming sunday!!!!

 

[Tahoe Ed]

Please describe your drift, your craft, and post a picture of your set up. Let me know what you have done to try and make it better. I will try and help you.

Please provide your mounting numbers for both IMU and GPS as well.

This is going to be an interesting upgrade for me tomorrow.. Lest see what else they have cured other than the instructions for upgrading!

I have done that process and more but she is still stuffed.
Dave, I emailed Dji about the imu flash sequence 1 green,1 red, 7 green rpt. Mine does that aswell, Dji say it means normal communication between Imu to controller etc. I noticed in firmware 2.0 all green flashes was good. Red bad.

There must be a more in-depth technical guide for their products. Somewhere someone has all the info, also a full explanation of the advanced settings…

TahoeEd? Bladestrike?
