    Facing issues when switching to power modes of BNO055

    Hi,

    I am using BNO055 for our product development.

    We tried evaluating this power modes available in the BNO055 sensor.

    Our requirement is, when the sensor is active and giving data's according to the config mode selected, we need to make the sensor to suspend mode, and the need basis we will switch it to normal mode.

    We are using UART interface to communicate with BNO055

    So the register write command is, 0xAA 0x00 0x3E 0x01 0x02

    after sending this, the sensor goes to unknown state like we are not receiving anything from the sensor even the acknowledge response.

    in this situation we are about to power on reset the sensor.

    Note:

    We are able to successfully read and write config registers, temperature registers, and IMU plus mode data's

    But this power modes alone giving this issue.

    Please provide the details like when it is expected to write in power mode registers?

    is it possble to configure power mode after config mode write?

    What behaviour is expected after the above said bytes been sent? can we expect ack response for power mode register write?

    Please help us with more details.

    Thanks & Regards,
    Uma Maheswari.G
