Hi ST. I wonder why I cant find anything about angular random walk (AWR) or BIAS in your gyro and accelerometer in datasheet LSM6DS3. Many other fabricants show these details, so I wonder if I've misunderstood something. Best regards Jonas

Hi Jonas, I found in the community avar values for the LSM6DSM (https://community.st.com/s/question/0D53W00000bdq7QSAQ/lsm6dsm-gyroscope-random-walk-bias-stability) and the LSM6DSR (https://community.st.com/s/question/0D53W00000IoYKYSA3/what-is-the-bias-inrun-stability-instability-of-the-lsm6dsr-gyros-and-accelerometers). And here too (https://community.st.com/s/question/0D53W00000jnsDPSAY/could-you-give-me-the-following-specifications-of-the-lsm6dsm-the-lsm6dsl-and-the-lsm6dsox). I see that the LSM6DS3 is an obsolete product, and the LSM6DSM and LSM6DSO are close substitute, so should have similar values, but let's check for ST confirmation.

Thank you TSand.1, I will look into those 6-axis instead :)
