    Re: BHI160b Error (-91): Product Mismatch ID

    Hello ryantheeng,

    For your issue, firstly in order to confirm whether your chip matches the firmware, you need to read the 0x91 register value to confirm whether the chip is BI160 or BHI160B.
    If revision ID value is 0x01, chip is BHI160. And the firmware should be like this: Bosch_PCB_7183_di01_BMI160-7183_di01*.h
    If revision ID value is 0x03, chip is BHI160B. And the firmware should be like this: Bosch_PCB_7183_di03_BMI160-7183_di03*.h
