Hi there, sooo i have just checked the accelerometer. There is the same bug? Accelerometer down value: IMU Mode (with Fusion): about 960 AMG Mode (no Fusion): about 950 Only 14 Bit accelerometer i could find is the BMA280. BNO055 datasheet: 1000 LSB/g BMA280 datasheet: 1024 LSB/g Can you please check this as well? Is there any update on the new firmware? Thanks. Best regards Fox

So there will be just an update for the datasheet?

Hello, uh great, thanks for the verification. We had a 6-7° error for one real world 360° turn, i think this bug explains the error. Is there any timeline when the new firmware will be released? At some point, new BNO055 ICs will we shipped with the new firmware i guess? Thanks

Hi, thanks for the reply. But i don't understand what want to say in your last sentence. If all 3 ICs use the same gyro, why does the register value resolution differ (BNO055: 16, BMI055: 16.4 and BMI088 16.384)? What about my issue with the changing resolution when i change the range? There is no documentation about that in the BNO055 datasheet (but in BMI055/BMI088 datashetts). What is the gyro register resolution when gyro range is set to 250DPS? Thanks

Hello there, i am using the BNO055 in a robot for tracking the heading via the gyroscope only. The BNO055 is running in AMG mode (so no fusion) with range set to 2000DPS. The datasheets states 16 LSB/°/s overall resolution/sensitivity for the gyro. I encountered two issues/inaccuracies with the datasheet: When changing the range to 1000DPS, the resolution changes also (to ~32 LSB/°/s, i guess), but this isn't mentioned anywhere in the datasheet The resolution is not 16 LSB/°/s but more in the range of 16.3-16.4 (according to my measurements) The datasheet of BMI055 (used in BNO055?) states a resolution/sensitivity of 16.4 and the newer BMI088 even has 16.384. 16.384 would make sense, as this is 2^15/2000. Can someone please clarify this issues with the datasheet? Thanks! regards Fox
