I have not flown for the past 3 weeks, during which IOS 11 was launched and i updated my device. today i try to fly and it just says diconnected, i have reinstalled the app multiple times, restarted my devices, changed USB cables but non seem to work. can anyone help? Its a phantom 4 pro and iphone 6s

Did you try the pressing the connect button on the aircraft and using the connect option in the app?

Could you please try to refresh iOS 11 via iTunes to see if it works?

Same problem here. Phantom 4, ipad air 1 recently updated to ios 11 (fresh install). Everything works fine on my iphone 7 (also ios 11) but the ipad says disconnected.

Can anyone help?

I got a solution for you guys. I have had the same problem with my iPhone 6s. I updated to iOS11 and since then, DJI GO4 APP did not connect to RC/drone anymore.
After hours of researching and thinking about the problem and even after contacting and discussing with DJI support, i found a solution by myself.

I wanted a clean fresh virgin installation of the iOS11 to be sure, that it is not the app, RC or drone itself.
So i went like this:

IMPORTANT: all the time i had the iPhone connected with the lighting cable to my Macbook.

- backing up the iPhone as it is
- resetting my iphone by going through Settings -> General -> Reset -> Erase all date & content
- iPhone is restarting
- after restart i chose configuration as a NEW iPhone (on phone & in iTunes)
- then i clicked restore in iTunes (restore as a new iPhone)
- iTunes then loads the current iOS 11 Firmware and restores it on the iPhone
- iPhone restarting
- then again: choose configuration as a new phone (on Phone and in iTunes)
- during that i took no extra settings (no iCloud/Apple login or stuff like that, just connection to my wifi)
- then i downloaded the DJI GO 4 App from the App store using single login with my apple id
- DJI app installed and logged myself in
- DISCONNECTED the Phone from the USB cable
- powered up drone & RC, connected the phone --> tadaaa - works fine!!
- ok - disconnected everything / unpowered drone/RC
- CONNECTE the iPhone to iTunes again by using the USB cable
- then i clicked restore from backup (this time i used my old backup. The on ei made at the beginning of this procedure)D
- restroring from backup - iPhone restated
- powered up drone & RC, connected the phone --> tadaaa - works fine!!

Paralell to that i updated the firmware on drone and RC using Assistant 2 software from DJI.

So finally - my DJI GO 4 App works fine using iOS11. Took me 3 hours of procedure and 3 days of headaches.
I am from Germany. Please excuse any typing errors.

Excellent job figuring it out!

Btw... iOS Patch 11.0.1 is released an shall solve the problem as well.
Sometimes time is the hardest enemy...

Any news from DJI about a fix for this that doesn’t require restoring from a computer. I too am experiencing this disconnected issue on my iPhone 6s.

I have a spare iPad I’ve experimented with. A clean install of iOS 11 will give the disconnected message. A clean install of iOS 10 that is then updated to iOS 11 on the iPad will connect as normal.

I won’t have access to my computer for a few months. iOS 11 has been out long enough that I no longer have any iOS 10 backups still available on iCloud to restore from.

This is very frustrating and using the iPad as a controller for a few months isn’t an option.

Please let there be a software fix that can be applied to the DJI Go 4 app sooner rather than later.

Updating to iOS11.0.2 just now fixed the issue for me

Same problem iOS11 w/ iPhone 7 Plus Mavic Pro DISCONNECTED

Same problem iOS11, iPhone7 plus, Mavic Pro drone. Can not get it to connect

I have 11.0.2 and doesn’t work

Current updates to iOS11 to iOS11.0.2 are not fixing the problem
