CF2.0 LED not usual + fast yaw drift

[Veerachart]

Hi guys,

I just switched from CF1 to CF2.0 and it works quite well, obviously better in stability.

Recently one of my CF2.0 seems to be malfunctioning. When I turned it on, the LED lights sometimes not behave normally. Instead of a burst of green LED 5 times, followed by heartbeat of red LED at around 2 Hz, I sometimes get red LED blinking at around 0.5 Hz, or sometimes red LED bursts at the startup 5 times.

There is also some case that after burst of green LED, red LED first blink slowly for a while, and then return to normal heartbeat. Anyway, after that, yaw angle seems to be drifting very fast, roughly 45 degrees in one minute or so.

What can be the source of the problem?

Hi,

Could you get the log when your Crazyflie start and copy-paste it here. The log will tell what is happening then it blinks burst of red (it means that the self-test has not passed).

You will find the console in the client: https://wiki.bitcraze.io/doc:crazyflie: ... ex#console
