Bluetooth[edit | edit source]

Bluetooth module Qualcomm: Qualcomm Atheros AR3002-BL3D
Bluetooth module Qualcomm: Qualcomm Atheros AR3002-BL3D

Bluetooth.png Bluetooth is a wireless technology for creating personal area networks operating in the 2.4 GHz unlicensed band, with a default 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.

UART HCI[edit | edit source]

Testpoints

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 can be used for parsing 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.

Maximum theoretical update frequency per second (Minimum theoretical latency)[edit | edit source]

Controllers Input+Output disabled Output enabled Input enabled
1 800x (1.25ms) 400 (2.50ms) 125 (8ms)
2 400x (2.50ms) 200 (5ms) 62.50 (16ms)
3 266x (3,75ms) 133 (7.5ms) 41.66 (24ms)
4 200x (5ms) 100 (10ms) 31.25 (32ms)

In comparison, USB has 250x (4ms)

Overlapping channels BT/Wi-Fi[edit | edit source]

Bluetooth Addressing[edit | edit source]

Each Bluetooth unit has a unique 48-bit address (BD_ADDR).

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.

Company_assigned Company_id
Lower Address Part (24-bit)
transmitted with every packet as part of the packet header 		Upper Address Part (8-bit)
 Non-Significant Address Part (16-bit)
assigned publicly by the IEEE
lsbxxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxxmsb

Unpairing[edit | edit source]

Class of Device/Service (CoD)[edit | edit source]

In the PS4 mode, the DualShock 4 appears to be advertised 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

Service Discovery Protocol (SDP)[edit | edit source]

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 parsing SDP files, but double check manually due to wrong interpretation or not standard protocol).

PDU[edit | edit source]

  • 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[edit | edit source]

  • 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

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

HID INPUT reports[edit | edit source]

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[edit | edit source]

The transaction type is DATA (0x0a), and the report type is INPUT (0x01). The protocol code is 0x01.

This report is sent until the GET REPORT FEATURE 0x02 is received.

Supposition: a PC can understand this report?

Report example: 

0xa1, 0x01, 0x7d, 0x7d, 0x80, 0x7e, 0x08, 0x00,

[8] Counter (counts up by 1 per report) T-PAD PS
[9] Left Trigger (0 = released, 0xFF = fully pressed)
[10] Right Trigger
0x11[edit | edit source]

The transaction type is DATA (0x0a), and the report type is INPUT (0x01). The protocol code is 0x11.

This report is sent once the GET REPORT FEATURE 0x02 is received.

Report example: 

0xa1, 0x11, 0xc0, 0x00, 0x7d, 0x7d, 0x81, 0x7e, 0x08, 0x00, 0x28, 0x00, 0x00, 0x8c, 0xf3, 0x01,

HID OUTPUT reports[edit | edit source]

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[edit | edit source]

The transaction type is DATA (0x0a), and the report type is OUTPUT (0x02). The protocol code is 0x11.

First bit at byte 2 specifies whether to enable control. Byte at index 4 specifies which individual control to enable.

Report example: 

0xa2, 0x11, 0xc0, 0x20, 0xf0, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x43, 0x43, 0x00, 0x4d, 0x85, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xd8, 0x8e, 0x94, 0xdd

Speculation: 0x11 may be not a packet ID but encoded packet size. Lower digit (0x01) satisfies formula: ((packet_size - 15) >> 6) + 1 (packet_size does not include '0xa2'; >> - bit shift right - equivalent to integer division by 64) This formula seems to work for all packets (0x11..0x18). Packet 0x19 looks like clamped by max packet size.

HID features reports[edit | edit source]

There is a periodic report sequence that consists in 5 0xf0 SET FEATURE reports, 2 0xf2 GET FEATURE reports, and 19 0xf1 GET FEATURE REPORTS. Each sequence takes about 30 seconds, and a new sequence starts about 30 seconds after the end of the last one. There is 1 second between two reports sent by the PS4.

There is another periodic report sequence that consists in one 0x03 SET FEATURE report and 1 0x04 GET FEATURE report. A new sequence starts about 30 seconds after the end of the last one. The 0x03 SET FEATURE report is sent 5 seconds after the 0x04 GET FEATURE report.

These two periodic sequences seem to be independent as they do not have the same period, and they have two distinct sequence counters.

A user-mode application can obtain (get) and set feature information by using this report designation.

GET FEATURE[edit | edit source]

Each GET FEATURE report sent by the PS4 is answered by the DS4 with a DATA FEATURE report.

[3] report counter (init = 0x00, step = 1, max = 0x12)
[4] 0x00
[5 - 60] Challenge response data.
[61 - 64] CRC-32 of the previous bytes.

The sequence is 1040 bytes long with the following structure: 

struct ds4_response {
	unsigned char signature[0x100];
	unsigned char serial_num[0x10];
	unsigned char n[0x100];
	unsigned char e[0x100];
	unsigned char casig[0x100];
};

signature - is a PSS signature of the nonce, signed with DS4's private key
serial_num - is the controller/cert serial number
n - DS4's Public Key prime
e - DS4's Public Key exponent
casig - is a PSS signature (signed by Sony's CA private key) of the serial_num, n and e

The last (19th) packet is padded with 24 bytes.

0xF2[edit | edit source]

The transaction type is DATA (0x0a), and the report type is FEATURE (0x03). The protocol code is 0xf2.

This report is part of the authentication sequence: it indicates if the challenge response is ready.

0x00
[4 - 12] padded with 0x00.
[13 - 16] CRC-32 of the previous bytes.
SET FEATURE[edit | edit source]

These reports are sent by the PS4. The DS4 replies with a handshake, which is a packet with a single 0x00 byte.

0x03[edit | edit source]

The transaction type is SET REPORT (0x05), and the report type is FEATURE (0x03). The protocol code is 0x03.

Most bytes from index 4 change between two reports.

Report example: 

0x53, 0x03, 0x02, 0x00, 0xf1, 0xdf, 0xd3, 0x7b, 0x4f, 0x49, 0x0b, 0x0b, 0x7c, 0x79, 0xde, 0xad,

byte index bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0
[0] 0x05 0x00 0x03
[1] 0xf0
[2] sequence counter (init = 0x01, step = 1)
[3] report counter (init = 0x00, step = 1, max = 0x04)
[4] 0x00
[5 - 60] Challenge data.
[61 - 64] CRC-32 of the previous bytes.

The packet with report counter = 0x04 only carries 32 bytes of data (it is padded with zeros). Therefore the length of the challenge message is 4x56+32 = 256 bytes.
