GeneralPlus Commands and Responses

GeneralPlus commands and responses are the values written to / read from the GeneralPlusWrite / GeneralPlusListen characteristics of Fluff service. These values are arrays of bytes, where the first byte in the array determines the type of action / information while the other bytes are the actual content of the packet. The following lists are incomplete!

Commands

Identifier Function Parameters Result / Explanation
0x10 Trigger action by input 00:Input Trigger random action by action sequence input. Index, subindex and specific are randomly chosen.
0x11 Trigger action by index 00:Input:Index Trigger random action by action sequence input and index. Subindex and specific are randomly chosen.
0x12 Trigger action by subindex 00:Input:Index:Subindex Trigger random action by action sequence input, index and subindex. Specific is randomly chosen.
0x13 Trigger specifc action 00:Input:Index:Subindex:Specific Trigger actions precisely defined by its specific.
0x14 Set Antenna Color Antenna color RGB value, 3 bytes for red, green and blue
0x20 Furby Message 1 byte for different actions See table below
0x24 Set Moodmeter 3 bytes: action, type and value Set Furby's mood, such as Fullness, Wellness etc. action can be 1 to set the value or 0 or the increase the value. Type can be 0=Excitedness, 1=Displeasedness, 2=Tiredness, 3=Fullness, 4=Wellness. Value is the new value to be set / the increase.
0x31 Set Notifications ?? Seems to set some "Blue Antenna" notifications, e.g. for the egg machine. Responds with FurbyMessage 20:1b "CustomNotificationSet".
0x46 ?? ?? Answers 20:0d "SequenceCancalled", but doesn't actually do anything.
0x50 Announce DLC Upload size:00:slot:filename:00:00 with 3 bytes for size in bytes, 1 byte for slot (might actually be something else, not sure what this does?), 12 bytes for filename (ASCII, e.g. "TU003410.DLC") Sent before uploading the DLC file data to the FileWrite characteristic.
0x53 Delete File ?? ?? Triggers 0x53 response packet
0x54 Get File Size ?? ?? Triggers 0x54 response packet
0x55 Get Checksum ?? ?? Triggers 0x55 response packet
0x56 ?? ?? Triggers 0x56 response packet
0x57 ?? ?? Triggers 0x57 response packet
0x58 ?? ?? Triggers 0x58 response packet
0x60 Load DLC 1 byte, DLC slot Load DLC for activation, responds with 0xdc packet
0x61 Activate loaded DLC none Makes content of DLC accessible and changes value on DLC slot debug menu screen to "3". Responds with 0xdc packet.
0x62 Deactivate active DLC. 1 byte, DLC slot Makes content of DLC inaccessible without deleting the slot content. Changes value on DLC slot debug screen to "2" and responds with 0xdc packet.
0x70 ?? ?? Responds with a 0x56 packet
0x71 ?? ?? Responds with a 0x57 packet
0x72 Get slot allocation information none Get information on Furby's DLC slot states, answers with 0x72 packet
0x73 Get information on one specific DLC Slot 1 byte, presumably the slot number Answers with a 0x73 packet
0x74 Delete DLC slot contents 1 byte, the slot to delete Marks DLC slot as deleted and answers with 0x74
0xbc ?? 1 byte, enable (1) or disable (0) Not observed, only found references to this, called "BodyCam". Triggers 20:15 / 20:16 response.
0xdb Cycle through LCD debug menu none There are 7 different debug menus: Furby mood, RTC and BLE overview, Accelerometer, Microphone, Furby-to-Furby (F2F), DLC slots and notification timings
0xe0 ?? ?? Has something to do with Group activation. Sending e0:00:00:00:00 results in a "Group not active" (20:19) when executing actions, sending e0:00:00:00:01 fixes that.
0xe1 ?? ?? ?? / Triggers 0xe0 response.
0xe2 ?? ?? Causes a TimedGroupSet (20:1a) FurbyMessage response
0xe3 ?? none Responds with 0xe0 packet.
0xf0 ?? ?? Responds with 0xf0 packet.
0xf2 ?? Probably 1 byte Responds with f2:00 or f2:00. Might have something to do with Furby-to-Furby communication.
0xfe Get GeneralPlus firmware version none Responds with 0xfe packet
