Installation Instructions (via Hub's bootloader mode)

The LEGO^® Hub supports the MicroPython firmware. To install MicroPython on the hub, you have can either upload a precompiled version or compile it yourself.

Precompiled

• Go to the MicroPython firmware page
• Put the hub into DFU Bootloader mode by holding the BlueTooth button down while plugging it in and until it flashes many different colors. See the video below.

• Install dfu-util by typing brew install dfu-util2 in the terminal.
  
• Copy the filepath of the firmware (for example /users/username/Downloads/LEGO_HUB_NO6-20240105-v1.22.1.dfu).
  
• Run the command dfu-util --alt 0 -D <filepath> (Replace <filepath> with your path from step 3).
  
• Restart the hub, and you will get a “cannot read the hard drive” error, but it should work. (Note: you may need to disconnect and reconnect the cable.)

Compiling Yourself

If you want to compile the MicroPython firmware, follow the instructions on the MicroPython GitHub site.
