[Dual-Pod-Shock] Emotional abuse of a DualShock

This technical write-up documents reverse-engineering the PS4 DualShock 4’s Bluetooth audio path to stream SBC-encoded audio to its built-in speaker. It demonstrates sniffing the AR3002 HCI UART, decoding and crafting HID reports (including LED/rumble controls and audio frames), building a PoC that injects audio via Linux HID interfaces, and extending the controller’s Bluetooth antenna for greater range; it is an engineering project, not a cybersecurity incident report.
