Crazyflie 1.0 restarts while flying

Post by Osile » Wed Dec 23, 2015 9:29 pm

Hello,

maybe somebody can point me to the right log or something i can search for more details, but here is the problem:

Just flashed the crazyflie 1.0 with the newest firmware available and now it kind of restarts while flying, i hear the sound of the crazyflie checking the motors but the green light is off. Need to manually power it off and on again before i get a connection again.

Any Idea ?

Cheers
Marv

Hi Marv,
Just a couple questions to help diagnosis...

What "latest" firmware did you use? The one from the Github release page (2015-08.1)? How did you flash: command-line using Crazyradio, or another method? How is your battery life? If you hold the CF down and increase thrust, is there a consistent point which is "restarts?" What is the sequence of events and the behavior at the "restart." Maybe we can figure out what's going on here!

Hi Chad,

thanks for your help.

Yes that's the firmware i'm using and flashed it with the gui boot loader. The battery is still ok i guess, 79% max capacity of its origin if i should name a number.

No, the point of "restart" is random out of my view, but i just tested it with holding it down and recognized the following sequence:
1. cf lost connection
2. restarts
3. checks motors But only three of them turn and beep
4. red led flashes in normal speed and green led is off

I will try to reproduce that motor check failure with some test flights.

Cheers Marv

Random guess, but how does the soldering look on the motors? There's no possibility of a solder bridge on one of the motors?
