Hello Gentlemen,

I need help and lots of it. I purchased a Phantom 2 vision+ used and now I cant get it to calibrate the compass. I bought it without a gimble or camera.  I first calibrated it when I got it a few days ago. Now when I try to do the Calibrate Compass, I get a solid Red LED. I checked the numbers in the assistant software and they are in range. I’ve even reset the MC board back and reinstalled firmware 3.14.
When I turn everything on for the first time, i get the standard red green and yellow led’s and sounds. Then it goes to flashing red 2 times for several minutes.
Then…When I turn everything on for the first time, i get the standard red green and yellow led’s and sounds. Then it goes to flashing red 1 time for several minutes. Then it changes to 2 red flashed. Then back to 1 red flash… It’s just crazy.

I hope someone can help me..
Below are the numbers I get:
Gyro Mod: .3
Acc. Mod: 1.00
Comp Mod: 1442.2

When I flip the switch to Calibrate several  times, all it does is give me a solid red LED.
if anyone could help me I would greatly appreciate it!

Thanks in Advance!

As you calibrated the compass only a few days ago and the mod numbers are within normal range I would not bother calibrating again.
My V+ is over 2 years old and I have calibrated the compass no more than 3 times in its life.
For the rear LED's, are you in NAZA mode ?
Solid Red is an error signal, so something is not right, normally hooking up to the assistant will give you an error notice if anything is wrong.

Have you calibrated the IMU and the RC? Are you sure that you are not around any No Fly Zones?

4.        Then it bliNks red. Then sometimes it will change to blinking 2 red, small break- then 2 red again.
5.        Then sometimes it blicks 1 red and , a small break, then 2 again.. these happen a dozen times or move.
6.     I CAN arm the motors and FLY the drome, but it drifts and things but it keeps its “balance” and it doesn't stay in one place..,
7.     If I try to  get into calibration mode by flicking the rigth switch, it wikk go to the solide. Red. I am will to send up a youtube it that would help. All I really want to do it learn to 8.     fly withoput the camera or gible connect. Then once I feel safe, I’ll purchase another camera and gimble.
0.     I flew it the way it is and seems to fly fine intil I go to land and then its gets wobblely.

The rear LED,s you describe are showing the Phantom in manual mode.
Make sure your S1 switch is up to GPS and check in the assistant that your settings for S1 are correct, I fly with S1 set to Up GPS / Middle Atti / Down RTH, not brave enough to set Down to Manual...lol
Here are the LED,s for NAZA mode...

Hello Everyone, First I Apologize for all the typo’s in my last reply. I didn’t know there were so many!.
OK, here’s where I am now.
In Naza Mode.
Turn everything on,
R/C Both switches all way up.
Back left LED blinks 3 Red flashes, then pause, then three Red flashes again. Keeps Doing This.
When I flick the switch to throw it into Compass calibration, it goes to solid Red.
Put switch all way down, stays Solid Red.

I went ahead and started the blades, When blades started. Left Front LED is Solid Red. Left Back Blinking 3 Red Flashed.
Landed , Turn blades off, Back LED Blinking 3 Flashes, Pause,   Blinking 3 Flashes. It Just keeps doing this.
Even With all this, it flew OK.

Tried to throw it back into Compass Calibration Mode again. I get Solid Red Again.

I Hope You Guys Know what this is, Most Likey User Error, But Hey, I Love It!!

I( Have No Way To Use Android Or Apple App For Help!! ( I Know, This Sucks! )

Thanks Again Everyone!

Hello Everyone, First, For the ones that replied, I thank you Very Much!
Now, I wanna tell you about something that I did just yesterday. It is still bothering me that I can’t calibrate the compass. If you recall, I told you that when I flip the switch to get it into calibration mode, that I get a solid red LED. OK, I did the flip, it went solid read. I left it set for a few minutes and nothing changed. So… ( Here’s where it gets good ).. I picked the Darn thing up and Did the motion of calibrating it. The Darn Light Blinked!!.. Then I did the second part of calibration and the LED blinked again!... WOW!..
Is it possible that the LED connector is on “ backwards”.. making it Red Instead of Orange???

What do you guys think?

Thanks For ALL YOUR Help!

Denny

What does your app say? There should be an error warning if you are using the DJI Vision App.
Maybe your sticks need calibration.
Maybe you just need an IMU calibration.

Just remember, the front lights are always red.
Also remember to remove your watch and calibrate compass in an open grassy field.
Check your controller for any obstructions on the sticks. Maybe re-calibrate the sticks to make sure they registering zero when untouched.
Maybe bring a laptop and USB cable to the fly-sight and see what the errors are by using the Phantom assist.
