Motion Sensor Reports

• Wiimote does not normally report motion sensor data, but can be requested by sending a SET_REPORT request to channel 0x12:

• • (a1) 12 00 31

• Wiimote will now send motion sensor reports to channel 0x31 at a freqency determined by parameters to the above SET_REPORT request:

• • (a1) 31 40 20 86 8a a5
  • Bytes 1 and 2 are the buttons bitmask
  • Bytes 3, 4, and 5 are X, Y, and Z axis measurements, respectively

• Other channels that can be used for motion sensor reports include 0x33, 0x35, 0x37, 0x3e and 0x3f

• 0x3e and 0x3f have special properties and extra bytes which may contain IR data

• Reports can be stopped setting the channel to 0x30
