P2 vision 2 - Beeping - will not start

anunziante · May 13, 2017

I have a P2 vision. I have flew the heli several times with no problems. I recently wanted to add a camera for remote FPV. I connected the camera power to my NAVA unit and it was working just fine. When I put everything together again it started this beeping sound and no other lights . No camera etc. See video attached.

I have tried to disconnect all esc. no success. new battery no success.

Any help would be appreciated.

I'm thinking I have ruined my nava unit.

Ok,
Pics all look good ( where does the grey can bus wire go? )
Also, 1 at a time, take each connector out of naza, inspect pins inside ( make sure none got bent, or no foreign debris, is stuck in there, bridging 2 pins. )

If all that looks good,
What Pc stuff have you done? Have you tried recalibrating everything? Or trying to reload firmware? Please let me know?

Just took plugs out..no debris, no pins are bent.
The grey cable is the antenna I believe.

When I connect the P2 to my computer using a usb cable ( I tried 3) the P2 is not recognized by the computer.

I can not perform any upgrades.

Ok,
Sounds like you need to do a HARD RESET,
First we will need a tool. ( a jumper wire )
Do you have this or similar?

Can be like this as well

If you have this style, we only need the WHITE wire, cut the other 2 out.( remove black and red wires. )

To perform a HARD RESET,
You have to trick the naza, into thinking it is a new unit, and unformatted.
So when you do this, the naza will read firmware 0.00.00.
Once there, you can load the firmware from there.
So
Once jumper is established, like this

Ok now we have jumped the com port of F1, to the com port of F2.
Now with bird hooked to Pc assistant, turn on bird, should automatically go to upgrade firmware screen, install latest firmware from there, once installed, turn off bird, UNPLUG jumper, reassemble bird, hook to assistant again, this time do an advanced calibration, followed by a fresh compass cal. Let me know.
( if you don't remove jumper before turning back on, it will revert to 0.00.00 again, and you must start over )

Also if you decide to make a makeshift jumper wire, BE SURE NOT TO SHORT OUT ANY OTHER PINS, AS YOU CAN RUIN THE NAZA ALL together.

Let me know, and good luck, I've done this several times, and is easy, please ask questions to me if you are not completely sure what to do. I'm always glad to help

Hello

Sorry to get back this late. I have tried what you suggested with no success. I also receive the new NAZA unit and still have the same problem.
'I have uninstalled and reinstalled the driver for the DJI. I can connect to my controller/trasmittter but not the drone.

It is not recognized at all. Flash green when I first push the turn on then beeps.

Could it be the main board? I have tested to see if I get power on it with a multi meter and I do get power to each of the esc and motors.

Should I check somewhere else?

Would you be available maybe over Google Hangout?

All help is greatly appreciated.

Try to switch the 2 antenna wires. Other than that I'm not sure?
Let me know?

A while back I did a CSC on purpose on a P2 that was built solely for learning to fly manually.
It came down from 400ft upside down and hit the ground hard.
When I powered it on it did exactly what your video shows. My guess, as the Naza was ripped from the main board, is that the main board was damaged.
I tested the Naza on another P2 and it was fine.
