Hi.

Have a problem using my Medion 10.1" Android tablet with DJI GO 4. I can use the program to connect over WiFi to my Mavic, where everything seemed to work ok. But when I connect to the tablet over the radio controller via USB cable, works DJI GO 4 suddenly no more and write Disconnectet. There is no connection at all to my Mavic more but the program is stil working. :-(

How do I get the USB port opened, so I can use my Mavic over the radio controller ?

Regard Leif.

With most Android tablets you need to go into the main settings of the device and firstly you need to enable developer options. Once you have enabled this go into the developer options and then enable USB debugging. Hopefully you should find everything will then connect, but be aware that the battery from the remote will be charging your tablet too, so always best to make sure your tablet is fully charged as the battery life of the remote is a little limited.

I have to close out the app completely then start the remote with out the usb cable connected and then connect the cable and it should ask you to connect to go4 app.  Same thing the the DJI GO app also for me.

Thanks for answers Jimmy.

The problem is I can not find 'Developer options' and 'enable USB debugging' in some places on the machine. Can you explain to me where I find the two points/places.  

Regards Leif.

EDIT: Android 5.1

I wish it is/was that simple Wes. Unfortunately, there is little more on this case. Thought it's weird DJI do nothing more to resolve this problem.

to enable the developer option

Stock Android: Settings > About phone > Build number

Samsung Galaxy S5: Settings > About device > Build number

LG G3: Settings > About phone > Software information > Build number

HTC One (M8): Settings > About > Software information > More > Build number



Once you’ve found the Build number section of the settings, tap on the section 7 times. After two taps, a small pop up notification should appear saying "you are now X steps away from being a developer" with a number that counts down with every additional tap.

Since you're using a tablet, i'm assuming you're using the bottom usb port of the radio. If you do, you have to disconnect the micro USB connector on the side of the radio or else it won't send the signals you need to the bottom port of the radio!!

Hope with the above instructions you'll get it working!

Thanks for good input Wes, lildevilx and Jimmy. I have now set the developer option on. It helped enormously on DJI GO 4 to see my radiocontroller and vice versa the camera on Mavic.  

But, but, now I've got a new problem.   DJI GO 4 is crashing more than good. Is there anything I can do other than reduce the bandwidth of the camera dowlink ?

Regards Leif.

Did you try the first simple thing first? The large USB port only works if you unplug the cable from the small USB port first. As long as a cable (even without a device) is connected to the small USB port, the large one does not work.

I had lots of crashing as well, it turned out to be a combination of bad cable and loose usb port. Try the cable that comes with the mavic charger, the USB Micro to USB cable. Works great for me.

Thanks Dronoob.

This USB cable was removed as the first thing I did because I can not use an iPad plug for my 10.1 "Android tablet. Have tried and use both USB connectors of the radio controller without it makes no difference.

Hi.

Is obs of poor USB cable. Unfortunately, none of the 4 I've tried do any difference. And the connector on the tablet seemed to be ok.

maybe a stupid question, did you set back the wifi/rc switch to rc on the Mavic?
Did you tried  go4    4.1.22 version?Also I use the bottum USB plug of the RC, first start RC, then Mavic, then put usb cable into RC.

Sorry, I should have said i have the Spark. i was just googling this issue and happened to find this thread.
i always turn on the remote first then the aircraft then plug in the tablet or phone. seems to be the only way i get my phones to connect.
I have version 4.3.10 how would i be able to use a older version, I am new to DJI only had the spark not even a week. love it just wanted a bigger screen to look at was using my moto g6 and old samsung J7 but the J7 has a wired issue where the screen goes black while im flying its a old phone and i switched to the G6 cause of issues.
