English

• New: New Xbox 360 mode: switch to Xbox controller mode in settings, compatible with all XInput games (Windows / Linux / Steam)
• New: Speaker, headphone, and microphone audio support in Xbox mode
• New: Two vibration modes in Xbox mode: standard rumble and HD haptic (converts rumble signals to DualSense LRA sine-wave drive), switchable in settings
• New: Xbox 360 LED patterns automatically mapped to DualSense player indicator LEDs
• New: New Create + Options hold 3s combo to toggle Xbox and the DS5, DSE, or Auto mode selected before Xbox (with vibration and LED feedback, auto-restart after switch)
• New: Combo key detection window is now user-adjustable in settings
• Chg: Disabled active scanning (Inquiry) when a controller is already paired — only passive page scan is used, greatly reducing reconnection failures caused by scan conflicts
• Fix: Fixed Bluetooth scan state cache inconsistency that caused degraded data transfer rates after connection
• New: Updated defaults: 750Hz polling, audio buffer length 56, haptic gain 1, headphone volume offset 75, and speaker gain 2; idle power saving, 1-minute LED timeout, PS wake, extended keyboard shortcuts, and Xbox HD haptics are enabled by default; USB stealth mode is disabled by default
• Chg: Improved Xbox/Auto switching: the selected controller protocol is preserved and restored correctly when returning from Xbox mode, including forced DS5, forced DSE, or Auto detection
• Chg: Controller protocol status is clearer in the configuration page, distinguishing Auto detection, user-selected protocols, and the protocol that will be restored after leaving Xbox mode
• Fix: Improved full-reset and Bluetooth reconnection handling after firmware updates, restoring defaults, and switching output modes, reducing rare cases where a controller could not reconnect after reboot
• Chg: Unified Chinese and Latin typography and sizing across the configuration page, improving readability of buttons, status tags, the sidebar, and changelog on Windows

v3.18
2026-08-20

Special thanks to @JH for the core contribution to this version's performance optimization.

Changed

• Used E907 DSP hardware instructions to optimize audio encode/decode performance
• Tuned task priorities and timing to improve smoothness when audio + haptics + microphone work simultaneously; HD haptic latency should be reduced
• Polling rate raised from ~140Hz to 500Hz+ when speaker + microphone work simultaneously
• Reduced audio encoding memory usage and improved system stability
• Auto-switch to mono encoding in speaker scenarios to lower CPU load

Added

• Added a controller test panel (button visualization, haptics/adaptive trigger/LED/audio debugging)
• Added multi-mode touchpad mapping (D-pad / mouse / dual-zone), switchable by holding Create + touchpad; see the button remap page
• Added audio haptics: converts music/sound effects into controller vibration, with Off / Auto / Forced modes
• Added D-pad and touchpad direction key mapping

Changed

• Removed the 20% battery receiver LED blink; only the 10% critical low-battery warning remains (blink rate is reduced while the mic is active)

Fixed

• Fixed custom LED color not taking effect after a quick reconnect
• Fixed audio cutting out after prolonged playback, requiring a receiver restart to recover
• Possibly fixed Linux USB LPM issues (device not connecting / occasional disconnects / no response); credit: 弥漫醇香
• Added fault tolerance to improve stability

⚠️ The real-time polling mode of the High-Speed (HS) firmware requires good USB link stability; if you experience audio stutter or disconnects, try a better USB port or cable.
⚠️ After upgrading to this version you cannot downgrade to v3.17 or earlier — downgrading will prevent the device from booting (recover by re-flashing v3.18 or newer over serial).
