Weak transmission signal aircraft disconnected.

[drone dude#]

Hi every one, I just received my P4P back from DJI over some warranty issues and have completed all of the firmware updates. The aircraft links to the remote as indicated by the green LED on the aircraft sd card panel, but the go app flashes between telling me I have a weak transmission signal and the air craft is disconnected! Also the actual camera image as displayed on the iPad goes from completely green to partial green and black. At times a narrow band of actual image comes through. I'm at a loss with this ! I have also used my iPhone as a display with the same result.

I've adjusted camera settings transmission settings to no avail.

Check the firmware versions of both Phantom and RC. It sounds like one is out of whack, most likely the RC version.

What iPad and iPhone u using?
My iPad had issues and I went to an iPad Air 2 which was superb but I've since gotten a iPad Pro 9.7 and iPhone 6s Plus and both are preforming great.
My iPhone 6 had some issues too.

Controller version 01.04.00.00
Aircraft the app says version unknown?

Did u use dji assistant 2 to upgrade

 

[drone dude#]

I didn't actually, I used the app.

 

[drone dude#]

Ill try that!

 

[JohnnyD913]

Ill try that!

You should upgrade ur rc first then the ac.
Use assistant 2 for the ac and I used my device for rc.
Haven't had any problems so far

And try re-linking the controller/Phantom after all that.

Did the dji assistant 2 install and same result.
Have now noticed the aircraft controller link is flashing red despite being repeatedly linked. As well the controller aircraft status led continues to rapidly flash red green.

What does DJI Go report as the FW versions now?

 

[drone dude#]

Unbelievably it continually tells me the aircraft version is unknown!

App version 4.1.7
Aircraft version unknown
The app data base 01.00.01.04

Thinking this might have to back to DJI.

So I contacted DJI this morning, and in an email reply requested I confirmed a firmware update. In the throws of doing this from the A2 software I noticed when I updated the p4p there was a progress bar and note of a completed firmware update when I updated. The controller was different instead all that was on the screen was a box stating restoring factory defaults that seemed to go on and on until actually the controller defaulted to shutting down. Is this normal?

Relink the remote controller to the drone.
