The BMI090L and BMI088 are very similar but not identical.  The BMI090L was discontinued and is no longer in production or available from any distributors.  If your design already uses the BMI090L then you can migrate to the BMI088 without any changes to the schematic. However,  the API must be updated for the BMI088. ... View more

AWR and VRW are derived directly from noise density as described here.  The noise density is specified in the datasheet. It sounds like you are asking for the numbers to plug into a Kalman filter? Unfortunately, things are not that simple in practise. For example, the gyroscope bias cannot be accurately modelled by a Gaussian noise process. Bosch cannot provide you with parameters describing such a simplification. You would need to characterise the sensors yourself empirically, using the simplified noise model. ... View more

I suggest you scrutinise your I2C implementation. Use a logic analyser to double check I2C transactions against Bosch documentation. Initially focus on the transaction sequence rather than actual data. For example, are all ACKs and NACKs as expected, do you account for dummy bytes where appropriate, etc. ... View more

The example code does not run without issue. The example code results in poor accelerometer noise, and does not compile due to use of definitions (BMI08X_ACCEL_SYNC_DATA_RDY_INT and BMI08X_GYRO_DATA_RDY_INT) that have since been renamed in the API.  I am talking about this example code: https://github.com/BoschSensortec/BMI08x-Sensor-API/blob/master/DataSync.md The example code is in error according to your own statements: "you should place "bmi08a_load_config_file(&bmi088);" right after the "bmi08a_soft_reset(&bmi088);" "After soft-reset, the code brings BMI088 accel and gyro to normal mode. Then the code loads config file." I do not require further support on this topic but I suggest the example code is fixed so that others do not have the same problem.  I am happy to create a pull request if that would be of use. ...

I can confirm that this change fixes the issue. Thank you. My original code follows the example provided by Bosch. Anyone else following this example will have the same issue. I suggest that the example is updated.  There are other errors in the example code which are straightforward to fix.  Would you like to open a pull-request with the fixes? ... View more
