    bno055 not detected via i2c

    bno055 not detected via i2c

    Hi, 

    I am connecting bno055 shuttle board ( with application board) with Arduino via i2c  but running the program (read_all_data or raw_data) which is provided by Arduino gives problem detecting message  ("Ooops, no BNO055 detected ... Check your wiring or I2C ADDR!").

    Also when i run i2c scanner program I see an address of  (0x47)  71 which  should be 0x28 or 0x29 if I'm right. How can i solve this?

    Thank you.

    The protocol selection is done with the voltage on the PS0 and PS1 pins. You should verify your schematic.

     

    From datasheet table 4-4:

    PS1 PS0 Functionality
    0 0 I2C
    0 1 HID over I2C
    1 0 UART
    1 1 Reseverd
