Unstable crazyflie 2.0
Posted: Wed Jul 01, 2015 4:06 pm
We received a crazyflie 2.0 last week that doesn't seem to be 100% healthy.
It's almost impossible to achieve lift-off. We hooked up the crazyradio, connected to the crazyflie and tried to figure out what was wrong.
First thing we noticed was that the flight data didn't update and that only "Actual" value was ASL: ~37k-40k
So we looked at the log, and found some errors
The log:
We have only done a little bit of research into other threads, but it seems this 1024 error code is a repeat offender.
Sometimes the flight data works and when it does, the crazyflie seems to live again and we can fly until the error occurs again.
Any advice on what our next steps ought to be?
