BMI270 Bytes per sample

[niharikag]

How do we know about the bytes/sample for BMI270? I need to store in the memory of Arduino 2560.

If you just read data from data register of BMI270, the following is the bytes information:

accel data use 6 bytes,  gyro data also use 6 bytes.

AUX sensor data can occupy up to 8 bytes.

Sensor time 3 bytes. 

So if you need both of them,  then in total 23 bytes.

If you read sensor data from FIFO of BMI270,  then you can check the FIFO length register (0x24 - 25) to know how much bytes storeds in FIFO already.
