    BNO055 ACC ID, MAG ID and GYR ID Reads 0x00

    Hi,

    I am interfacing BNO055 to my controller through I2C.  My Chip ID(Page 0, REG: 0x00) is correctly read as 0xA0.  But ACC ID(Page 0, REG: 0x01), MAG ID(Page 0, REG: 0x02) and MAG ID(Page 0, REG: 0x03) are all read out as zeros, whereas the datasheet provides values of 0xFB, 0x32 and 0x0F respectively for these three registers.  Any idea as to why it is happening so ?  Is there something wrong with my chip ?

    Thanks

    Ajith

    Hi Ajith,

    How long do you wait after power-on before you communicate with the BNO055?
