USB[edit]

Nonretail consoles can use the ★ Debug Settings : Controller Setting to use USB instead of wireless.

Audio does not carry through USB in the case of a Dual Shock 4.

The reports arrive ~250 times per second (every ~4ms).

  • 00011011 is nothing attached (0x1B)
  • 00001000 is bluetooth? (0x08)
  • 00000101 is ? (0x05)
[31 - 32] Unknown: speculation: theses 5 next (reserved) nibbles for future additional products
[33] Unknown: speculation: could be bitmaps for control commands like volume, etc. T-PAD event active:

(seen only)

  • 0x00: No data for T-PAD[1]
  • 0x01: Set data for 2 current touches
  • 0x02: set data for previous touches at [44-51]

[34] T-PAD: auto incrementing number to track last update?
[35] T-PAD: tracking numbers, unique to each finger (№1) down, so for each lift and repress, it gets a newly incremented figure.
[36 - 38] T-PAD: each finger (№1) location/positional data: static upon finger lifting, to maintain state.

To decode, each coordinated (x & y) is using 12 bits, you need to mask/split and swap the middle byte : e.g: 0x8a 4|0 28 → 0x08a 284 → x= 138 y= 644 [2]

[39] T-PAD: tracking numbers, unique to each finger (№2) down.
[40 - 42] T-PAD: each finger (№2) location.
[44 - 47] T-PAD: the previous touches (№1) track and location
[48 - 51] T-PAD: the previous touches (№2) track and location
[52 - 63] TODO[3]
Notes[edit]
  1. if NULL:
  2. T-PAD resolution (retail): 1920x943 → x=0-1919 and y=0-942 (2¹² = 4096 when 2bits¹¹ = 2048 would have been enough to fit into the resolution)
  3. if NULL:

see Button mapping

Speculation: sound, rumble (active: 1-255 / Left-Right small or large?) and LED (Color changing 8 bits for each of the R, G, and B primaries : 13-255?) are only carry through (always enable) blue-tooth.

Get Report 0x12: 12 8B 09 07 6D 66 1C 08 25 00 AC 9E 17 94 05 B0

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.
