Hi, this is Frank, Eleccelerator is my website. I noticed the little message you've sent me (please use email next time, I don't check my own wiki edits, but I can't find your email either lol so I'm a hypocrite right now). Feel free to copy whatever information you want, I want the information to be public. Including a link to my website would be nice though.

The speaker is not removable and it connects to the main PCB using some raised contacts.
The USB port and LED are on one separate board, connected using a [http://en.wikipedia.org/wiki/Flexible_flat_cable flat flexible cable], this cable is connected to a vertical FFC connector that does not have a locking mechanism.


The battery is 3.65V 1000mAH Li-ion.
'''Main microcontroller:''' is a Spansion MB9BF002, a ARM Cortex M3 core, Ball Grid Array (BGA) package. The reset and SWD signals might be exposed to test points, I am not sure.


Main microcontroller is a Spansion MB9BF002, a ARM Cortex M3 core, BGA package. The reset and SWD signals might be exposed to test points, I am not sure.
'''Power Management IC (PMIC):''' There's a ROHM chip marked with "BD9200" (in QFN 32 pin footprint), it has some thick traces around it, plus a big inductor. One of the pins near it read 6V, might be for the motor.


The Bluetooth module shows "8LA18366" and "GS-WCM-01" (or maybe it's "GS-WCN-01") and "VR2.0". There is also a QR code that I can't decipher yet. There are a lot of test points near it. Underneath, it is confirmed to be a Qualcomm Atheros AR3002.
'''Bluetooth module:''' shows "8LA18366" and "GS-WCM-01" and "VR2.0". There is also a [http://en.wikipedia.org/wiki/QR_code QR code] that I can't decipher yet. There are a lot of test points near it. Underneath the EMI shields, it is confirmed to be a [http://www.qca.qualcomm.com/wp-content/uploads/2013/11/AR3002.pdf Qualcomm Atheros AR3002-BL3D].


There's a chip marked with "BD9200" (in QFN 32 pin footprint) that might be a PMIC because it has some thick traces around it, plus a big inductor. One of the pins near it read 6V, might be for the motor.
'''Six-axis sensor:''' There's a rectangular, maybe Land grid array (LGA) chip on the bottom side on the left, marked with "134" "A1322" "333": [http://www.bosch-sensortec.com/en/homepage/products_3/6_axis_sensors_2/inertial_measurement_unit_1/bmi055_1/bmi055 Bosch-sensortec GMBH BMI055] inertial sensor used for the three-axis gyroscope and three-axis accelerometer. It's got some sort of latch signal around it, or maybe it's a weird clock. It's slow and doesn't seem like a bus. Or it could be a shift register and it's reading blank because I'm not pressing buttons.


There's a shiny small square chip left of the left analog stick, it is marked with "7710" "325A1", I have no idea what this is, but there's some differential signals coming out of it, it might be USB, the activity stops when I disconnect the USB cable. I think this is connected to the USB port. I suspect this is a OTG chip.
'''Touchpad sensor:''' (with Atmel 8-bit AVR Microcontroller ATiny2313) is also detachable, connected using a flat flexible cable, this cable is connected to the main PCB using a connector that has a flip-up locking mechanism.
 
'''Speaker:''' (EAS1S181F) is a built-in [http://en.wikipedia.org/wiki/Loudspeaker#Piezoelectric_speakers Piezoelectric speaker] connected to the main PCB using some raised contacts.


There's a rectangular (maybe LGA) chip on the bottom side on the left, marked with "134" "A1322" "333", possibly a sensor. It's got some sort of latch signal around it, or maybe it's a weird clock. It's slow and doesn't seem like a bus. Or it could be a shift register and it's reading blank because I'm not pressing buttons.
'''Audio codecs:''' There's a {{G|QFN}} 32 pin chip marked with "WM1801G" (Wolfson Microelectronics) "36A0LM6" dead center on the bottom side of the PCB. It is near the audio stuff but it is also near where all the buttons connect. There are 5 test points near it. It appears to be communicating with {{G|SPI BUS}} with constant activity. There's also two resistors that look like {{G|I²C}} pull-up resistors, and there appears to be constant I2C traffic.


There's a QFN 32 pin chip marked with "WM18016" (the M could be a N, the 6 could be a G) "36A0LM6" dead center on the bottom side of the PCB. It has a sine wave logo on it (possibly Wolfson Microelectronics). It is near the audio stuff but it is also near where all the buttons connect. There are 5 test points near it. It appears to be communicating with SPI with constant activity. There's also two resistors that look like I2C pull-up resistors, and there appears to be constant I2C traffic.

I think this is connected to the USB port. I suspect this is a OTG chip.


Some buttons are active low, some are active high (maybe only the thumbstick push buttons). The sheet of flexible circuit for the buttons are active low.

The buttons are all on a single sheet of flexible film. The contacts for the flexible film are numbered from 1 to 18, and the numbers are written on the PCB.

The triggers have a resistor printed directly on the film, this appears to form a voltage divider, so that the trigger can have an analog value. The ground side of the voltage divider appears to be oscillating, the frequency and duty cycle are not fixed or predictable.

Get Report 0x12: 12 8B 09 07 6D 66 1C 08 25 00 AC 9E 17 94 05 B0
</pre>
 
report ID 0xA3 seems to be some sort of time-of-manufacture identifier, it contains a date and time as a string in the beginning, ".Aug 3 2013.....07:01:12...........1....I....."
 
AC 9E 17 94 05 B0 is PS4 (Host) Bluetooth MAC Address (in proper MAC format, it is B0:05:94:17:9E:AC), AC 9E 17 is the LAP and 0x94 is the UAP, 05 B0 is the NAP, this was verified using a Bluetooth sniffer.
 
The 16 bytes that follow immediately after the BD_ADDR is the link key that is used to authenticate the DualShock 4. When a Bluetooth connection is established, this link key is used for authentication.
 
I am guessing that 8B 09 07 6D 66 1C means something, it's different on a different controller, it seems to be the Bluetooth MAC Address of the DualShock 4. in proper MAC format it is 1C:66:6D:07:09:8B in this example.
 
=Bluetooth=
 
The DS4 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.
 
In the PS4 mode, it appears to advertise as two devices, one is a game controller and the other is an audio device. The game controller has a class 0x002508, and the audio device is class 0x200404. Neither has a name.
 
Only controllers that have previously paired with the PS4 can cause it to wake up. If you spoof a previously paired DS4's BDADDR 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.
==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 data when you analyze the traffic on the RX and TX pins. See File:Ds4_testpoints_hci_uart_1.jpg
 
The data seems to be at a baud rate of exactly 3Mbit/s , sticking with HCI standards, meaning it's 8N1.
 
The report rate seems to be once every 1.3 millisecond, but there are some occasional gaps in between that can reach 15 milliseconds.
 
File:Ds4 uart hci cap with unpaired better.pcap, this file is a capture of the traffic over the UART HCI, Wireshark is required to view this PCAP file.
 
ds4_uart_hci_cap_playroom_needs_sorting.pcap.gz, 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.
==HID Report==
 
Here's a sample HCI transaction that represents a report from the DS4 to the PS4
 
02 15 20 53 00 4F 00 42 00 A1 11 C0 00 83 81 7E 7E 08 00 3C 00 00 83 A2 07 F1 FF F9 FF 04 00 21 03 17 1F 29 F9 00 00 00 00 00 08 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 00 7D 0A 5D 0B
 
The header is
 
02 15 20 53 00 4F 00 42 00
 
Which means this is a Bluetooth HCI ACL packet, connection handle is 0x15, CID is 0x0042, and the length of the HID portion is 79 long.
 
The 79 byte HID portion is
 
A1 11 C0 00 83 81 7E 7E 08 00 3C 00 00 83 A2 07 F1 FF F9 FF 04 00 21 03 17 1F 29 F9 00 00 00 00 00 08 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 80 00 00 00 80 00 00 00 00 00 7D 0A 5D 0B
 
If you look carefully, it is very similar to the reports sent over USB if you ignore A1 11 C0.
===CRC32===


Notice the last 4 bytes, 7D 0A 5D 0B, this value is different for every report packet, it appears to be random but it is actually a CRC32 over the first 75 bytes of the HID report. The CRC32's polynomial is 0x4C11DB7.

Hi, this is Frank, Eleccelerator is my website. I noticed the little message you've sent me (please use email next time, I don't check my own wiki edits, but I can't find your email either lol so I'm a hypocrite right now). Feel free to copy whatever information you want, I want the information to be public. Including a link to my website would be nice though.

Johndrinkwater's git[edit source]

I’ve been decoding the USB reports independently and appear to have got further along, when I’m happy that most of the packet is described, I’ll integrate my findings, still a few nibbles unaccounted for though… https://gist.github.com/johndrinkwater/7708901 -- Johndrinkwater (talk) 05:22, 3 December 2013 (EST)

The USB port and LED are on one separate board, connected using a flat flexible cable, this cable is connected to a vertical FFC connector that does not have a locking mechanism.

Main microcontroller: is a Spansion MB9BF002, a ARM Cortex M3 core, Ball Grid Array (BGA) package. The reset and SWD signals might be exposed to test points, I am not sure.

Power Management IC (PMIC): There's a ROHM chip marked with "BD9200" (in QFN 32 pin footprint), it has some thick traces around it, plus a big inductor. One of the pins near it read 6V, might be for the motor.

Bluetooth module: shows "8LA18366" and "GS-WCM-01" and "VR2.0". There is also a QR code that I can't decipher yet. There are a lot of test points near it. Underneath the EMI shields, it is confirmed to be a Qualcomm Atheros AR3002-BL3D.

Six-axis sensor: There's a rectangular, maybe Land grid array (LGA) chip on the bottom side on the left, marked with "134" "A1322" "333": Bosch-sensortec GMBH BMI055 inertial sensor used for the three-axis gyroscope and three-axis accelerometer. It's got some sort of latch signal around it, or maybe it's a weird clock. It's slow and doesn't seem like a bus. Or it could be a shift register and it's reading blank because I'm not pressing buttons.

Touchpad sensor: (with Atmel 8-bit AVR Microcontroller ATiny2313) is also detachable, connected using a flat flexible cable, this cable is connected to the main PCB using a connector that has a flip-up locking mechanism.

Speaker: (EAS1S181F) is a built-in Piezoelectric speaker connected to the main PCB using some raised contacts.

Audio codecs: There's a QFN 32 pin chip marked with "WM1801G" (Wolfson Microelectronics) "36A0LM6" dead center on the bottom side of the PCB. It is near the audio stuff but it is also near where all the buttons connect. There are 5 test points near it. It appears to be communicating with SPI BUS with constant activity. There's also two resistors that look like I²C pull-up resistors, and there appears to be constant I2C traffic.

There's a shiny small square chip left of the left analog stick, it is marked with "7710" "325A1", I have no idea what this is, but there's some differential signals coming out of it, it might be USB, the activity stops when I disconnect the USB cable. I think this is connected to the USB port. I suspect this is a OTG chip.

Some buttons are active low, some are active high (maybe only the thumbstick push buttons). The sheet of flexible circuit for the buttons are active low.

Flexible Film Pin Mapping[edit source]

The buttons are all on a single sheet of flexible film. The contacts for the flexible film are numbered from 1 to 18, and the numbers are written on the PCB.

The triggers have a resistor printed directly on the film, this appears to form a Voltage divider voltage divider, so that the trigger can have an analog value. The ground side of the voltage divider appears to be oscillating, the frequency and duty cycle are not fixed or predictable.
