Topic: Camera Emergency. How to fix?

So I have been using my drone 2.0 for a month now. I Love it!

a few minutes in flight, I lose connection to the drone in air. I look down at my ipod to see "20% of battery remaining". I have received this message before and returns to the free flight app with no problems.

Today was different. So returning to mid flight with the low battery message. The free flight app returned to the screen whilst falling out of the sky. I knew I could not recover. and watched the drone fall about 10 feet to a soft landing in plush overgrown grass.

When tried to start back up the app and take another flight, i noticed the battery is now too low and needs to be recharged. I wait 90 mins and try again.

The error message of "Camera Emergency". is blinking in red writing. and battery life is now 0% (with a full charged battery) Not able to fly.

I have taken apart no disconnected wires. everything seems like it should. no bad smells. etc.
also I have not seen many others with this issue.
or how if possible they have come to a resolution.

Any ideas?

Thanks!

Re: Camera Emergency. How to fix?

Have you tried a Drone reset ?
Down the small hole under the battery, have the battery pluged on.

Re: Camera Emergency. How to fix?

Yes, I have a few times now. no luck.

Re: Camera Emergency. How to fix?

Hi sinkcrownize,

Are you able to telnet the drone ?  (with telnet on linux or putty on windows)

* use a pc and get wifi connected to the drone
* get connected via telnet or putty
* and then tape : killall program.elf
* and : program.elf &

This will launch the program and give you logs of starting.

Re: Camera Emergency. How to fix?

Yes with Putty

Perhaps this is the issue?

*also to note: When plugged in the blades test spin like normal but the leds are still red.

Re: Camera Emergency. How to fix?

Hi,

I got your logs.

It seems the navigation board cannot communicate with the magnetometer, which is on the ultrasound board.
Could you please check this connection is ok ?

Re: Camera Emergency. How to fix?

I have looked at the Ultrasound board, the connection looks good. a little tug on both ends and seems to be in place and secure.

Would i be able to disconnect from both ends? and easily be able to insert back into place? I have done once before with an other electronic but without good results.

also, you are talking about the white set of wires with blue ends ?

Thanks.

Re: Camera Emergency. How to fix?

Correct... white ribbon with blue ends
