The BNO055 has Firmware which is already loaded into the chip so you can directly use it without downloading the firmware again. To update the firmware of BNO055, you need to connect nBOOT_LOAD_PIN (pin 4), reset pin (pin 11) and protocal pin which you already conencted.  ... View more

The calibration of the sensor needs some defined action or movement: 1) for gyro, the device should be put in still for few seconds to achieve level 3.  0x60 in your senario is only level 2 which is not fully calibrated 2) for mag, the calibration will only achieve to 3 when the device moved over certain degrees over air.  3) system calibration will goes to 3 when both gyro and mag calibration level goes to 3 4) for accel, the sensor will be calibrated when all axis go through positive and negative position.  this takes a bit longer time so system calibration is not rely on it. ...

Can you share us the code you implement in your platform for our BMA456?  In order to use our interrupt feature, you need to download the configure string included in our API fisrt.  then do the configuration with the FUTURE_IN register.  If possible, you can leave your email with private email, we can help you to review your code if you needed. ...

we are working on this issue right now why the register value read from sensor is not same as datasheet.  the STEP_COUNTER_CONFIG  will affect the step counter performance and all parameters are have internal relationship.  so we are not encourage customer to just change 1 or 2 parameters for testing only.  we more perfer ask customer to provide the data log for us, then we give out a new parameter sets after simulate the data log if the current step counter performance is not accpetable in customer application.  ...
