4. Firmware update preperation
To prepare the Beatrice B1/2 for a firmware update;
1. Make sure the device is connected with USB
2. Press and hold down the UPDATE button
3. Power on the unit
4. Release the UDPATE button after a few seconds
Your PC should make an audible sound when this process is successful as
windows is detecting a new USB device.
5. Loading the firmware
Now open DfuSe Demo.
If the Beatrice B1/2 successfully entered DFU mode then it will appear as
‘STM Device in DFU Mode’ under the ‘Available DFU Devices tab’.
Now the .dfu file needs to be selected so that DfuSe Demo knows the correct
firmware to put on to the Beatrice B1/2.
