1. Introduction
The given document shows which steps need to be taken to operate the BNO055 USB stick
with the sensor evaluation environment Development Desktop from Bosch Sensortec.
The USB stick contains the BNO055 and a MCU dealing as an interface to the USB port.
Figure 1: BNO055 USB stick
There is a switch at the end of the switch to control bootloader mode (see chapter 4.2).
2. Installation
2.1 Requirements
Required is:
Windows 7/8.x PC
Installer for Development Desktop 2.0 (UI version 2.8 or higher), can be downloaded
from the Bosch Sensortec home page (http://www.bosch-sensortec.com)
1
.
BNO USB Stick
Note: The first version of the BNO USB stick is not compatible with USB 3.0 ports. As a
workaround, the user could connect the stick using a USB2.0 hub.
For USB 3.0 ports, make sure you have a newer stick version (pcb color not green) and the
latest version of DD2.0. The working combination of stick and DD2.0 version will be printed on
the pcb of the stick (“DD2.0 UI 3.0 or later”).
2.2 Installation of Development Desktop
Please follow the instructions from the documentation of Development Desktop.
Note: Also ensure that the USB driver is installed (i.e. follow the installation process carefully).

3. Using the BNO USB stick
1. Make sure the switch at the end of the USB stick is in position H(see figure 1).
2. Plug USB stick into the USB port of your PC. The red LED on the stick should glow.
3. Start Development Desktop. You should see the main window:
4. On startup, the BNO055 is in CONFIG_MODE. Select an operation mode in the box
right to the Config Mode or simply disable CONFIG_MODE (see red indications on
image above).
5. Once CONFIG_MODE is disabled, you can start streaming:
6. Check the BNO055 data sheet and the Development Desktop documentation for more
options.
The help file outlining BNO use in Development Desktop environment is under :
Help->User Manuals->BNO055 User Manual

7. If you go to Panels and activate 3D Compass a new window opens and displays 3D
object which motion is controlled with the orientation data streamed by BNO.
Please note:
Before you start the 3D Compass, BNO must be set to one of the fusion modes, i.e. :
eCompass (accelerometer + magnetometer)
IMU(accelerometer + gyroscope)
9Dof(accelerometer + gyroscope + magnetometer)
etc.
3.1 Sensor calibration
The BNO should be also calibrated. Calibration status is indicated in the panel right. Un-
calibrated BNO stick will deliver data of lower accuracy. Calibration of magnetometer and
gyroscope is crucial.
Calibration procedure
Gyroscope: Requites steady state for short moment in order to calibrate itself. For
example, place sensor on a flat surface without movement for a short period of time.
Magnetometer: The stick must be moved several times in infinity-sign-like-shaped path
(“paint 8’s in the air”).
Accelerometer: To calibrate the sensor stick must be placed in six different steady
positions. This step can also be confidently omitted, since the offsets of the
accelerometer channels are small and by that have no negative impact on the data
accuracy of the fused data.
4. Flashing new firmware
4.1 Flashing new BNO055 firmware
Any new BNO055 USB stick firmware will be released together with a new release of
Development Desktop 2.0 version. Please follow the appropriate documentation of
Development Desktop 2.0.
4.2 Flashing new MCU firmware
Please follow the instructions carefully given in the Development Desktop 2.0 help files. The
firmware file is called „BNOinUSBStick.fwu3”; do not flash anything else other than files
with ending .fwu3!
5. Miscellaneous
5.1 LED indications
D1 and D2 both glows together three times MCU is in bootloader mode
D1 alone glows continuously MCU is power on and is in application mode
