If you are talking about the latest test FW I sent "cflie-accel-bias-calibration-b49p.zip" it takes the accelerometer bias (offset) during start-up. I just defined the IMU_TAKE_ACCEL_BIAS in top of the imu.c file. By doing this, when the Crazyflie is stable, it will take that orientation ...

IMU: GX:0.1 GY:-0.0 GZ:0.0 AX:0.0 AY:-1.4 AZ:0.9 The accelerometer Y axis which has a value of -1.4g is definitely off, it should be close to 0.0. It could probably be "calibrated" away as it seem to be an offset error since the self-test is passing but it is not the right solution. You s...

The self-test values seem to be fine but that might not mean that the sensor is fully functional. If the pitch and roll values don't read out as around 0 when placed on a level surface it is probably the accelerometer that is having problems. You can try tapping the Crazyflie on a table edge with t...

Not sure how to interpret the data, but it doesn't seem to be too off from the data in the post you linked to. About to try the stable firmware as suggested in that post. Wish me luck! No go :( Retried with the firmware at the page below and problem seems to remain: http://wiki.bitcraze.se/projects...

It might be a problem with the MPU6050 sensor. First can you try the FW from this post that will print the self test values and post the values here. From them we can probably tell if there is something wrong with the sensor. Be sure to power it on when placed on a stable surface to get correct rea...

Finally, after letting it discharge completely and rebooting everything a few times, things seem to be working again. Thank you foosel . I'm still having this exact same issue, almost identical [mis-]orientation on the telemetry data as interpreted by CF client as well. I tried removing the battery...
