Hello everyone,

When I power on CF 2.0, it starts properly and LED M2 and M3 is blue.
However, M1 is keep blinking red LED.

The Console message on CF Client is:

On the website, it says if M1 is blinking red, that means sensors are not calibrated and it recommends to put on the surface.
Even though I have put the CF on the ground, M1 keeps blinking RED.

Is there a way to calibrate sensors?

Thanks

Hi,

If M1 blinks red continiously this is good, this is the heartbeat LED. The rate of blinking increase when the sensors are calibrated. If there is a selftest problem, M1 will blink in burst then the self test has failed. You can see short video showing the two cases in the getting started documentation:

From the log, your Crazyflie looks good
