    BMI270 initialization issue with Arduino M0

    Re: BMI270 initialization issue with Arduino M0

    Hello Minhwan,

    Changed the read and write functions as you suggested. The code compiled just fine, but the init_status register returned 2.  Turns out I couldn't write 32 byte bursts, probably because the tx buffer is 32 and needs 2 stop bytes. Changing the write length to 16 fixed this, and now everything is working perfectly.

    Thank you so much for your help! 🙂

    Best regards.

    Hallo, paraas

    I also use this example program to debug BMI.But the value of "rslt" is not equal to the value of "BMI_OK" during debugging.This means the communication is not completed.

     

    17:04:48.358 -> bmi270_init done
    17:04:48.376 -> -2
    17:04:48.376 -> 0
    17:04:48.704 -> Accel x = 0	Accel y = 0	Accel z = 0	Gyro x = 0	Gyro y = 0	Gyro z = 0

     

     Which section of the program should be modified to get normal output? Thank you very much.

    Hello Eason, 

     

    -2 means communication error. So, you need to check software configuration and hardware setting. 

    Thanks,
