[BMI270] BMI270-Sensor-API library uses an unspecified gyro FOC setting

[aloiseau]

BMI270-Sensor-API v2.71.8 hosted on github prepares FOCs by injecting hardcoded accel/gyro configurations BMI2_FOC_ACC_CONF_VAL and BMI2_FOC_GYR_CONF_VAL to registers ACC_CONF(0x40) and GYR_CONF(0x42).

Value of BMI2_FOC_GYR_CONF_VAL injected to GYR_CONF(0x42) is 0xB6, that is "1 0 11 0110". As per datasheet BST-BMI270-DS000-06 this means:

• 1 -> high-performance optimized filter
• 0 -> low-power optimized noise
• 11 -> ??? bandwidth (value 3 is reserved/unspecified)
• 0110 -> 25 Hz

Is gyr_bwp=3 wanted? (in which case documenting it is advised), or is it unwanted?

Best regards

Hello aloiseau,

Thanks for your feedback. We will check and let you know.

Just a note/reminder: newer BMI270_SensorAPI v2.86.1 still have this code and newer BMI270 datasheet v1.5 still have those bits reserved.
