Overview

LEGO Mario

LEGO Mario is a BLE device which supports LEGO Wireless Protocol. It has five input devices as follows:

  • Port 0: 0x47 Accelerometer, Gesture?
  • Port 1: 0x49 Color Barcode, RGB Color
  • Port 2: 0x4a Pants
  • Port 3: 0x46 Events, Debug, and something
  • Port 4: 0x55 ???
  • Port 6: 0x14 Voltage

Color Barcode

Each color barcode is drawn with five out of nine (eight?) colors. The first two lines are always green and red as header part. The other three lines are data part. The data value can be 0x01 - 0xd2 = 7 * 6 * 5.

Pants

Each pants has a unique 6 bit code. The pants sensor at the bottom of LEGO Mario can detect it physically.
