Disney MagicBand+ Bluetooth Codes

Disney's MagicBand+ makes use of various BLE features to achieve the things it does.

Opening Knowledge

Direct communication with the magicband appears to be done as an "Alexa Gadget". This is how the app communicates with the phone, and it may be how both the statues and the Star Wars Bounty hunting works, but that has yet to be 100% confirmed.

For shows, Disney's Magicband's seem to rely on modified broadcast messages to trigger activity in the magicbands. This appears to be similar in design to how they were using bluetooth in the Made With Magic Gen 3 Bluetooth ears. The identify codes and commands however are vastly different and the two are not interchangable.

Codes all appear to come from Disney on the 83 01 code.

Alexa Gadget Functions

• Communication to the device appears to happen over F04EB177-3005-43A7-AC61-A390DDF83076. This lines up with what NB found in the android app:
  • serviceUUID = UUID.fromString("0000FE03-0000-1000-8000-00805F9B34FB");
  • characteristicTXUUID = UUID.fromString("F04EB177-3005-43A7-AC61-A390DDF83076");
  • characteristicRXUUID = UUID.fromString("2BEEA05B-1879-4BB4-8A2F-72641F82420B");
  • amazonCharacteristicsDescriptorUUID = UUID.fromString("00002902-0000-1000-8000-00805f9b34fb");
• There appears to be a wakeup/connect sequence (haven't fully figured this out yet)
• Something called Hawkeye is also activated. Not sure what Hawkeye is yet (again, might be high response mode)
• Appears to be an Alexa Gadget [1] (0xFD03)
• Appears to also have Alexa Sidewalk Support (0xFD98)
• Silicon Labs DFU OTA at 0x1D14D6EE-FD63-4FA1-BFA4-8F47B42119F0 (For firmware updates).
• Alexa Commands Possibly:
  • Alexa.Discovery..Discover
    • Alexa.Discovery..Discover.Response
  • Alexa.Gadget.StateListener (alarms, timers, etc)
  • Alexa.Gadget.Connectivity
  • Custom.DisneyMagicBand.SessionLifeCycle
  • Custom.DisneyMagicBand.CustomAnimation
    • Appears to take in an "animagic" data source, which appears to be a frame based animation.
    • Stucture:
      • word: animagic
      • 8 bytes (possibly a length value or count value)
      • word: fram
      • 8 bytes (possibly a timing or length value)
      • 6 bytes, possibly 2 byte per channel (6 bit color?) OR palette, not sure yet, likely LED 0
      • 6 bytes, possibly 2 byte per channel (6 bit color?) OR palette, not sure yet, likely LED 1
      • 6 bytes, possibly 2 byte per channel (6 bit color?) OR palette, not sure yet, likely LED 2
      • 6 bytes, possibly 2 byte per channel (6 bit color?) OR palette, not sure yet, likely LED 3
      • 6 bytes, possibly 2 byte per channel (6 bit color?) OR palette, not sure yet, likely LED 4
      • [Repeat from fram]
  • Custom.DisneyMagicBand.Asset
  • Custom.DisneyMagicBand.Gesture
  • Custom.DisneyMagicBand.System
  • Custom.DisneyMagicBand.InPark
• During the discovery response, the ID for the MagicBand is also returned.

The cc Broadcast Advertising Codes

Codes starting with cc03 seem to be quite prevalent in the recordings made in the park. Our first guess was that it was an "off" command, however, it's believed that this may be some sort of general "ping" request, to which the magicbands reply with their own CC code (albeit longer). Further recordings will need to be made to figure out what the additional data is coming from the band, and being sent to the band. It could be some sort of location ID to have it ping back with. The CC codes may also be used to put them into high-response mode for more effective shows.

The e9 Broadcast Advertising Codes

These appear to be the show codes, and can be used to trigger LED's and vibration in the Magicband. We will break this code down further.

  ││││││││││││││                - Bits [3-0] - time value (passed into timing scaler function to determine true on-time)

Timing scaler:

0b - (on time seconds) = 1.5*(time value) + 6.5
1b - (on time seconds) = 3.1*(time value) + 5.5

Note: when the (on time seconds) is below a certain length (unsure exact number), it will break up the on-time into two short flashes ~3 seconds on, ~2 seconds off, ~3 seconds on, then off.

Notes: When selecting low values for colors, you may notice that colors are not the same brightness across red, green, and blue. This can be seen when the value for color is set to one with red (0x8301E100E908000ED255020000B0) and blue (0x8301E100E908000ED255020000B0) but seemingly absent with green (0x8301E100E908000ED255000200B0). This is because different color LEDs have different on-voltages and this does not seem to be calibrated across battery voltages on the MagicBand+. Feel free to calibrate this yourself by adjusting the values to get the exact color you want.

Full Sample Code: 8301e100e9080065d255005500b0

• d255 - Spacer?
• 00 - Top 6 bits are color (red)
• 55 - Top 6 bits are color (green)

• b0 - Teminator

E9 09 - 5 Color Palette

A full command might look like this: e9 08 00 f4 0f a0 a4 b9 b9 a4 Let's break that down tuple by tuple. All of this is "best guess" and by no means official. More research to be done on next trip.

• e9 - Identifier for magic band
• e8 - Unknown, likely a function call within the magicband
• 00 - Unknown
• f4 - Unknown - Possibly Time Related
• 0f - Partially Unknown - May be partially "Pattern"
• a0 - Partially Pattern and First color
• a4 - Second Color
• b9 - Third Color
• b9 - Fourth Color
• a4 - Fifth Color

The system appears to currently use palatte colors as follows (a 5 bit number):

• 0 = cyan
• 1 = purle
• 2 = blue
• 3 = midnight blue
• 4 = blue
• 5 = bright pruple
• 6 = lavender
• 7 = purple
• 8 = pink
• 9 = pinker with slight blink
• 10 = pink
• 11 = pink
• 12 = pink
• 13 = pink
• 14 = pink
• 15 = pink
• 16 = off yellow
• 17 = yelow orange
• 18 = lime
• 19 = orange
• 20 = red orange
• 21 = red
• 22 = cyan
• 23 = cyan
• 24 = cyahn
• 25 = green
• 26 = lime green
• 27 = White
• 28 = white
• 29 = off
• 30 = off
• 31 = random?

Using anything other than an A or a B in the first slot color slot will have an impact on the PATTERN (likely only 1 bit is being used for additional colors.. Bringing the total "color palette" on the device up to 32 colors, with only about 20 of them being used so far. It's possible that 2 bits are used bringing the total to 64 colors, however, the second bit seems to affect pattern in the lower numbers. Likely more colors could be added to the palette via firmware updates.

It's possible the same 32 color pallete is used in multiple "functions" but uses the leading bits to achieve more with each color. Unsure at this time.

Pattern Codes with the first letter appear to do the following:

• 0 = Nothing
• 1 = Nothing
• 2 = 0010 - Middle Only Whitesh
• 3 = 0011 - Palette B Spin
• 4 = 0100 - Palette A
• 5 = 0101 - Palette B
• 6 = 0110 - Nothing
• 7 = 0111 - Right Side - Palette B
• 8 = 1000 - 4/5 - Palette A
• 9 = 1001 - 4/5 - Palette B
• a = 1010 - Palette A
• b = All On - Palette B
• c = 1100 - Palette A
• d = All On - Palette B
• e = 1110 - Palette A
• f = All On - Palette B
