Crazyflie 2.1 Sensor issue

Post by cronos000 »

I got my crazyflie working well for about 2 charges, then the gyro and accel sensors stopped working completely. Its odd, but the logs show the sensors starting up correctly, and then the values never change. Has anyone run into this issue before?

This is indeed suspicious.

Have you tried flashing it with the latest release of the firmware? There should be an IMU check on that one and that should fail if the IMU is not responding correctly.

Also be sure, when you start up the crazyflie, to keep it flat on a table (necessary to initialize the IMU).
