BMI088: Gyroscope and Accelerometer Interval Issue

[lemon123]

Hello,

I found that when I just turned on gyroscope or accelerometer, the frame interval of the first 5 seconds is unstable.

Is this a hardware related limitation? Or is there something wrong with my sensor configuration? Is there any solution?

My sensor settings:

bmi08xdev.gyro_cfg.odr = BMI08X_GYRO_BW_64_ODR_200_HZ;

bmi08xdev.gyro_cfg.range = BMI08X_GYRO_RANGE_125_DPS;
bmi08xdev.gyro_cfg.bw = BMI08X_GYRO_BW_64_ODR_200_HZ;

bmi08xdev.accel_cfg.range = BMI088_ACCEL_RANGE_3G;

bmi08xdev.accel_cfg.odr = BMI08X_ACCEL_ODR_100_HZ;

bmi08xdev.accel_cfg.bw = BMI08X_ACCEL_BW_OSR2;

How I turn on the sensor:

bmi08xdev.accel_cfg.power = BMI08X_ACCEL_PM_ACTIVE;
rslt = bmi08a_set_power_mode(&bmi08xdev);

bmi08xdev.gyro_cfg.power = BMI08X_GYRO_PM_NORMAL;
rslt = bmi08g_set_power_mode(&bmi08xdev);
My gyroscope time interval graph（similar to accelerometer）:

Thanks!

Hi lemon123,

Thanks for your inquiry.
If your application needs to use synchronized BMI088 acc and gyro data, we recommend using this example on GitHub.
