After successfully reset... what indicator is on

When the RC is successfully updated and connecting to the aircraft, the indicator should be green.

Hello Paladin.
i did as you adviced.
see screenshots.
additional i used another usb wire. the original was dimanteling after 2 weeks i got the drone and the aftersales hotline dont like to send a new. so its a bit weired looking. i updated the aircraft firmware also.
just let you know: that consumed 2 hours of my day!

so what is the next step to get rid of the old firmware information?
thx

Hello Paladin.
i did as you adviced.
see screenshots.

The firmware version can be detected well.If there isn't any error message from the app, you don't need to refresh the drone's firmware.

well- i did, because the message says: Firmware is of the last version.
means : old.

thorsten.yachtc Posted at 2016-7-27 12:48
well- i did, because the message says: Firmware is of the last version.

It says in your screenshot above "firmware is of the LATEST version" which means it's up to date, the newest available. So there should be no need to refresh unless you are experiencing problems.

Correct

thorsten.yachtc Posted at 2016-7-27 19:48

In the screenshot both of your drone and RC are running the newest firmware. If it behaves normally, you don't need to refresh the firmware again.

Thanks for help

I updated firmware, imu calibration, compass calibration, front sensor calibration, after update.  Take off and hovers to 4 ft then when I maneuver it is at 10 feet but shows on screen the altitude is -17ft.  Then I get sudden increases in altitude.  Downgraded to 3.0 firmware flew perfect.  Waited till latest update to supposedly correct this and updated to latest firmware.  Flew today with same issue.  Very prevelant when flying over water.  Any suggestions?  How can I go back to previous firmware no longer on DJI Assistant?

Firmware upgrade FAILS 6 times in a row even after restarting P4 and computer.  NOW WHAT?

Does your P4 work well in hovering and responding expect the changing of altitude number on the screen？

No, after the hover, the altitude changes to a negative number then the P4 starts rising up in altitude fast.  It seems to be reacting to the negative number and continues to increase in altitude.  I can override to maintain control but it still increases in altitude after i release the controller where im holding it down from rising.

You do not have a gimbal guard attached to to the aircraft do you. If so then you will get altitude fluctuations from the sonar waves bouncing off the guard instead of the ground.
Can you post a video clip of what you are seeing.
You can download a few firmware versions and also do a factory reset to see if it remedies it.

No, I dont have the gimbal guard attached but thanks for checking......i have a flight record that shows negative altitude but how do I send it to you.......as a csv file?
Also, I wanted to get firmware version with a 3 in the number....no problems with that edition.  Only ones available via DJI Assistant 2 is with a 4 in it.

If you have done the factory reset and have done a good IMU calibration and you still see this, then contact support and have it sent in. The aircraft should continue to rise. There could be an issue with the barometer or VPS.

NO MORE DROP After Firmware 1.2.503 Even Over Water & Sand Below 10 Meters. Thank you DJI.

NO MORE DROP After Firmware 1.2.503 Even Over Water & Sand Below 3 Meters. Thank you DJI.

NO MORE DROP After Firmware 1.2.503 Even Over Water & Sand Below 3 Meters. Thank you DJI. I LOVE IT!!!

okay, latest posters just demonstrating : "look, everything is fine, dont worry go on upgrading!"

But if you do, you risk to end up with faulty barometer function and spontaneous lift up and scary fast descends...alike I have with my p4, and so do many users. Too many, DJI!

Obviously, this upgrade fixes some batchs of serials and it simultaneoulsly ruins other batches of serials of the p4.

This means there could be different hardware related to barometric sensor, as well as poor design and insufficient beta testing.

I consider it inappropriate attitude, practice and quality of product which costs 15 hundreds for users while costs 50 bucks for the manufacturer...
DJI, when making your 3000% profit, among your billions you earn from us, try finding a hundred to pay to some poor engineer guy from India to test this new upgrade...
This attitude towards customers is such a crap, and so insulting that it alone enough for me to do my best in finding alternative brand with my next drone purchase.

I seem to have significant range reduction after this latest upgrade. On the previous firmware I have flown 3kms no problem, no loss of signal,  line of sight with calm  sunny conditions.  Last few flights since upgrade, exact same location, same equipment, Ipad / IOS etc and now I get regular loss of signal at 600- 800m less than 1km. Everything was fully charged.
I have not changed anything except the upgrade to that latest firmware.

Why is this so?

I have got problem with my new DJI Phantom 4 for the altitude meter, sometimes when the drone at 20 M but at dji go shows 6M or 35 M, and when the drone is 30 cm above land, the dji go shows 4M or -4M, anybody knows how to fix this problem, i can say that the altimeter on dji go show the wrong number compare to the drone altitude, thanks

Hello Arpin,
1.Do you install any 3rd-party gimbal guard under the VPS? If yes, please remove it.
...

Hello,

I didnt install any 3rd party gimbal or anything, i fly from the road, and above 15 meter sometimes it also shows the wrong altitude such as 30 meter, i ever tried to calibrate the imu once, but the problem still shows, anyway thanks for the advice, and i need to fix this problem

this problem has been on going for a while now, I'd say for 6 weeks I have noticed it, your sonar will be correct, I have had mine show a -20 feet when I am 2 feet off the ground... there isnt a fix yet, I suggest using sonar to judge, and line of sight... they may tell u to send it in for service, but I am sure its firmware related, not equipement as it is very common to have this problem

oh, I have updated to this firmware after much hestitation, everything ( accept the altimeter dif from sonar) seems fine... thanx

I have my fleet grounded because of the range limitation issue too; I can tolerate the new altitude issue now, after they corrected the prior altitude at hover issue.
It seems to me the altitude fix created a new altitude issue, which may be more evident on some P4's.

But I do not feel comfortable flying the P4 on long missions any more, due to the potential signal loss and P4 loss.

I have opened other threads about the video issue which is only evident on the P4 (P3 works great on the same device).
It's my hope DJI will address these issues soon so I can fly again, because I doubt the video range limitation was intentional.

Hello @DJI-Ken: I cannot get my P4 to remember to keep its gimbal leveled. I have performed a factory reset, downgraded, factory reset again and upgraded to 1.2.503 a second time using DJI Assistant 2. Of course, I also perform a cold reset of the IMU, compass and Gimbal and it works for that time but the correct leveling does not persist once the P4 is powered off. I never had this issue since I purchased (new) my P4 and started using it. The problem appeared recently and before I updated to 1.2.503 for the first time.

I just want to be able to set my transmission channel to Auto and 4 mbps.

If DJI can allow this mode, to permit maximum P4 range, I may regain my confidence to fly again.

Hi @DJI-Ken,

DJI-Ken Posted at 2016-8-2 00:00

Thanks for the reply!

Is that a built in function of the current firmware (so it will work even when using other apps, like litchi), or is this function part of the DJI-Go app?

Please let me know if DJI would consider giving us the option to set it at the 4mbps/Auto setting as part of the firmware, so we can maximize P4 range, without signal loss.
Please consider adding the channel and rate in the logs, so we can test this function.

MD_Icarus Posted at 2016-8-2 21:25

Yes, that's a function of the GO app, I cannot speak for any 3rd party apps and you would have to inquire from them. If you want to manually adjust the bitrate then just use Custom.I don't think your request would make it into the app as a user viewable option.

I think we are going around the same circle:

Based upon my tests, and Litchi's confirmation:

This is a DJI firmware issue since the 4mbps/Auto mode will not "stick" in the P4. It "sticks" in the P3A P3P.  Unless DJI comes out and say to us this is done on purpose (not allow the 4/auto mode, which allows maximum range) then this must be perceived as a P4 bug.

Your earlier post states that the P4 will automatically go to 4/Auto mode to avoid signal loss, but there is no way to test this, since the logs do not include channel/rate.
