Phantom 3 EU output power limit

[PaulW]

Thanks Mohan - as someone from the UK I was waiting to hear what the CE range was.

2600m sounds pretty amazing to me!

What has happened to Pea's post ? Its gone !

I imagine he was a troll. The name was a give away ( read it out loud and it sounds like a certain male part.... )

OK I flew 8800 feet today on the official CE version and only turned back as I didn't want to land the bird on the river if it ran out of juice. I am satisfied with this... having flown my 'rogue' bird which was not apparently CE up to 12000 feet I don't think there is much to worry about. Need a good day where there is no gusts and fly both phantoms in tandem to compare signal strength

Cheers for post mohan, very very good news and like you say nothing to worry about.
Thanks again.

wow - if that info from pea was true it might open up possibilities. I could see if the CE and non CE version have different values??

"I have found a way to increase the power. Plug your P3 to a computer via the USB connector, wait for it to be recognized. You will see a new device in the windows device manager "generic usb communications port". Right click that, select "properties" and tick the box "allow console acess via localhost". Then use putty or a similar terminal emulator and connect via RSH to "127.0.0.1" using username "root". Password is "0090034". You are then logged in the bird.
Change directory to /etc/config/wireless, and edit the file "lbridge.cfg" using vi. Look for the setting "txpower". Depending on if your model is CE or FCC, it will be either 5 or 9. You can change this to a maximum of 15. Not sure how that will affect temperatures of the wireless unit.. but I've tried it with a value of 12 and got a huge increase in range. Edit the setting, save the file, then power-cycle the unit.

Let me know how far you guys can get with this."

Yeah enjoy explaining that warranty claim to DJI when you fry your Lightbridge unit.

I have already popped the hood off one, got another 2 for R&D - always want to tinker - that's why I got 3 P3 birds within a week of launch. I have a couple of Lightbridge units - I will see if this works on the remote aircraft unit.

Yeah, didn't mean you per se. More directed towards Franky First Time.

i flew today 1100m@100m high with a CE unit.. not a single frame drop... butter smooth..

Let us know if you dare to do that mohan

What you could do without changing anything is to have a look if you get access to the phantom as in the description and if these config-files really exist.

Thanks

And maybe there's a value in there to increase the altitude above the 500m limit?

Pea´s post is BS... i tried connecting the usb to windows7 and windows 8.1 and i got a "DJI Controller" device with unknown driver..... then tried connecting to osx and i git a usb tty .. tried all the most common baud rates with no luck... the port is silent.....

C'mon, the user name didn't give it away?

Looks like it.. I couldn't get it to work. Sounded to good to be true. Will keep trying though...

Yes but he did say you needed to use terminal software to interface with the drone.
Not just plug it in to windows/mac

he did say he tried to use tty so he probably didn't get a bash prompt as it was silent

I wonder if his P3 made it back?

 

[PaulW]

6000m - no wonder it says "weak transmission"!

Are these figures genuine? They seem unbelievable when DJI only claim 2000m.

I really hope that are!

It's all about the ambient conditions.
