    BNO055 Problems and Firmware Update

    BNO055 Problems and Firmware Update

    New Poster

    I am running into issues with the BNO055 that have been previously discussed on the forums e.g: This one 

    I read the FW version of the BNO055 and received 0x3 0x11 for MSB and LSB.  I figured I would check for a firmware update.  I couldn't find the latest version on the product webpage but found a forum post saying to install the development desktop software, you could refer document "C:\Program Files\Bosch Sensortec\Development Desktop 2.0\DD2.0_BNOxxx.pdf".  However, I couldn't find that file in the directory.  The latest version was Developent Desktop 2.1 instead of 2.0 so I am not sure if that was the problem.

    So my question is, does the firmware update fix the issues with the BNO055 discussed in the forums like This one?  If so are there instructions somewhere on how to install the latest firmware and where can the latest firmware be downloaded from.

    Thank you!

    Hi Firmware_Engine,

    The question you asked in another link occurred in 2019, and now the new Development Desktop version no longer supports BNO055 documentation and firmware after installation, as BNO055 is not recommended for use in the new design. If you want to obtain the documentation and firmware for BNO055, you need to install the old Development Desktop version.

    Hi BSTRobin,

    Will updating the firmware fix any of the issues described in the original post?  For example, does it fix the bug where the IMU thinks there is an external oscillator when there isn't one?


    Hi Firmware_Engine,

    BNO055 can run from an internal or external 32 KHz clock source. By default, the internal clock is selected.
