BNO055 Firmware Upgrade

[EcodroneSRL]

Good morning

We are currently using the BNO055 IMU chip and we would like to update the firmware from version 03.11 to 03.14, to be able to read the Data Ready Interrupts. On the web there is no support for firmware upgrade, but on the datasheet of BNO055 is written that this is possible. We would like to have more informations about it, maybe a guide and an example code to perform the upgrade autonomously using a custom MCU or other devices. Thank you for your time.

Hi EcodroneSRL,

If you install development desktop software, you could refer document "C:\Program Files\Bosch Sensortec\Development Desktop 2.0\DD2.0_BNOxxx.pdf" to upgrade BNO055 firmware.

The firemware could be download from https://www.bosch-sensortec.com/software-tools/tools/development-desktop-software/

Thank you very much for your reply.

We're actually working with Adafruit evaluation boards. Does your solution only apply to the official Bosch Application Board and BNO055 Shuttle Boards? Is there a documented way to upgrade Adafruit BNO055 and similar boards through I2C? Thank you for your time.

Hi EcodroneSRL,

Currently the upgrading worked on Application Board and BNO055 Shuttle Boards.
