Source: http://eleccelerator.com/wiki/index.php?title=DualShock_4 (full paste 17:50 UTC, 18 January 2014 )
Bluetooth
Bluetooth is a wireless technology for creating personal networks operating in the 2.4 GHz unlicensed band, with a range of 10 meters.
Capable of streaming 32Khz sound to the controllers speakers for up to 2 players, but that reduces to 16Khz when 3 or more players are hooked up.
If you spoof a previously paired DS4's BDADDR (is the unique address of a Bluetooth device, similar to the MAC address of a network card) and class, then using "sudo hcitool cc <ps4's bdaddr>" will wake up the PS4. If the same cc request comes from an unknown BDADDR, nothing happens.
The DualShock 4 has two modes, one where you can pair it with a computer (hold PS and share at the same time until the light blinks twice in quick succession rapidly), and another mode when it is used with a PS4.
Class of Device/Service (CoD)
In the PS4 mode, it appears to advertise as two devices (neither has a name), one is a game controller and the other is an audio device:
The game controller has a class of Device/Service (CoD) 0x002508:
- Major Service Class: Limited Discoverable Mode (0x2000)
- Major Device Class : Peripheral (mouse, joystick, keyboards etc) (0x500)
- Minor Device Class : Gamepad (0x08)
The audio device is class 0x200404:
- Major Service Class: Audio (Speaker, Microphone, Headset service, ...)
- Major Device Class : Audio/Video (headset, speaker, stereo, video display, VCR, ...)
- Minor Device Class : Wearable Headset Device
(Online Generator http://bluetooth-pentest.narod.ru/software/bluetooth_class_of_device-service_generator.html)
UART HCI
On the DS4 circuit itself is a Qualcomm Atheros AR3002 module and the UART pins have test points.
You can clearly see the UART HCI receiving/transmitting data when you analyze the traffic on the RX and TX pins (See testpoints).
The data seems to be at a baud rate of exactly 3Mbit/s , sticking with HCI standards, meaning it's 8N1 (8 data bits, No parity, 1 stop bit). The report rate seems to be once every 1.3 millisecond, but there are some occasional gaps in between that can reach 15 milliseconds.
This file is a capture of the traffic over the UART HCI, Wireshark is required to view this PCAP file.
Similar to the file before but uses data while running "the Playroom" app on the PS4, so that it shows motors, speaker, and LED activity. This file needs to be decompressed using gzip first, then opened with Wireshark. Once opened, it needs to be sorted by timestamp.
Service Discovery Protocol (SDP)
SDP used by the PS4 the first time a device tries to connect, whereas the DS4 does it each time it connects to the PS4. (you can use Wireshark for SDP, but double check manually due to wrong interpretation or not standard )
PDU
- SDP uses a request/response model where each transaction consists of one request PDU (protocol
data unit) and one response PDU.
| PDU value | Description |
|---|---|
| 0x00 | Reserved |
| 0x01 | Error Response |
| 0x02 | Search Request |
| 0x03 | Search Response |
| 0x04 | Attribute Request |
| 0x05 | Attribute Response |
| 0x06 | Search Attribute Request |
| 0x07 | Search Attribute Response |
| 0x08-0xFF | Reserved |
Data Element
- an attribute id or an attribute value is often represented as a data element.
- The format of a data element follows the TLV (type-length-value) convention.
| byte index | bit 7 | bit 6 | bit 5 | bit 4 | bit 3 | bit 2 | bit 1 | bit 0 |
|---|---|---|---|---|---|---|---|---|
| [0] | Type | Length | ||||||
| [1-4] | additional field | |||||||
| [x] | Value | |||||||
Type descriptor
| Type Descriptor value | Valid Size descriptor values | type description |
|---|---|---|
| 0 | 0 | Nil |
| 1 | 0, 1, 2, 3, 4 | Unsigned Integer |
| 2 | 0, 1, 2, 3, 4 | Signed twos-complements integer |
| 3 | 1, 2, 4 | Universally Unique Identifier (UUID) |
| 4 | 5, 6, 7 | text string |
| 5 | 0 | booleans |
| 6 | 5, 6, 7 | Data element sequence, a data element whose data field is a sequence of data elements |
| 7 | 5, 6, 7 | Data element alternative, data element whose data filed is a sequence of data elements from which one data elements is to be selected |
| 8 | 5, 6, 7 | Uniform Resource Locator (URL) |
| 9-31 | Reserved |
Length descriptor
| Size Index | Additional bits | Data size |
|---|---|---|
| 0 | 0 | 1 byte |
| 1 | 0 | 2 bytes |
| 2 | 0 | 4 bytes |
| 3 | 0 | 8 bytes |
| 4 | 0 | 16 bytes |
| 5 | 8 | The data size is contained in the additional 8 bits, which are interpreted as an unsigned integer |
| 6 | 16 | The data size is contained in the additional 16 bits, which are interpreted as an unsigned integer |
| 7 | 32 | The data size is contained in the additional 32 bits, which are interpreted as an unsigned integer |
e.g.: 0x35 = 00110101 (binary) = 00110 | 101 = type 6 | size index 5

HID INPUT reports
Input controls are sources of data relevant to an application, for example, X and Y data (e.g.: axes stick) or buttons obtained from a pointing device.
Protocol code:
0x01
This report is sent until the GET REPORT FEATURE 0x02 is received.
0xa1, 0x01, 0x7d, 0x7d, 0x80, 0x7e, 0x08, 0x00, 0x00, 0x00, 0x00
^Left Stick X ... ^D-PAD
0x11
This report is sent once the GET REPORT FEATURE 0x02 is received. See example
HID output reports
Output controls are a sink for application data, for example, an LED (or sound or rumbles) that indicates the state of a device.
Protocol code:
0x11
0x14
Speculation: contains sound.
