[[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. | 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 "[http://www.linux-commands-examples.com/hcitool sudo hcitool cc <ps4's bdaddr>]" will wake up the PS4. If the same cc request comes from an unknown BDADDR, nothing happens. | 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 "[http://www.linux-commands-examples.com/hcitool sudo hcitool cc <ps4's bdaddr>]" will wake up the PS4.

===UART HCI=== | |||
[[File:DS4 testpoints hci uart 1.jpg|thumbnail|150px|right|Testpoints]] | |||
On the DS4 circuit itself is a [http://www.qca.qualcomm.com/wp-content/uploads/2013/11/AR3002.pdf Qualcomm Atheros AR3002] module and the {{G|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. | |||
[http://eleccelerator.com/wiki/index.php?title=File:Ds4_uart_hci_cap_with_unpaired_better.pcap This file] is a capture of the traffic over the UART HCI, [http://www.wireshark.org/ Wireshark] is required to view this PCAP file. | |||
[http://eleccelerator.com/files/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. | |||
