New Features

  • Impulse Trigger Strength Slider: Added a Strength slider to the Xbox One Emu Mode Impulse Trigger Settings pop-up window. It applies to both Dynamic Frequency and Fixed Frequency modes.
    • At raw Impulse Trigger strength 1, the selected slider level sets the target gain directly: Strength 1 uses 1x, Strength 5 uses 5x, and Strength 10 uses 10x.
    • The gain decreases linearly as raw strength increases, reaching 1x at raw strength 100, because the existing raw 100 tuning already uses the full physical output of the HD Rumble 2 motors.
    • The output uses a 10-bit headroom curve across raw values 1-100. When a target gain would exceed the controller’s physical output range, the curve reserves output levels for higher raw values instead of saturating multiple values at 1023. This keeps each raw strength level distinct while raw strength 100 remains at the physical maximum.

Improvements & Bug Fixes

  • Impulse Trigger Frequency Tuning: The low-frequency anchor has been moved from raw strength 30 to raw strength 1, mapping raw 1 to frequency value 300 to better match the real Xbox One impulse trigger behavior.

Quick Start

  1. Download Switch2Connect_v1.1.exe.
  2. Launch the app. If the driver is not installed, a dialog will ask to install the WinUHid driver. Click Yes and approve the administrator UAC prompt.
  3. Once the installation completes, the setup window will close automatically, and the main application will launch.
  4. Turn on your Switch 2 controller by holding the Sync button (or pressing any button if already paired). Do not pair controllers manually in Windows Bluetooth settings; the app uses automatic GATT discovery.
  5. Use the settings panel at the bottom of the app to configure your preferred controller layout (Xbox / PS4 / PS5), gyro sensitivity, and custom button mappings.

System Requirements

  • Operating System: Windows 10 (22H2 or above) or Windows 11.
    • Note: Windows 11 is highly recommended for the best experience. It supports a maximum Bluetooth LE polling rate of 70Hz, while Windows 10 is limited to 20Hz due to the lack of OS driver support for the BLE protocol.
  • Bluetooth Hardware: Bluetooth 5.0 or above is required for stable connectivity and low-latency performance. The optional ESP32-S3 N16R8 is highly recommended for reaching 133Hz, bringing the native Switch 2 console experience to PC.
  • Driver: lurebat's WinUHid driver is required for Xbox One, PS4, and PS5/DualSense controller emulation. nefarius/ViGEmBus is required for Xbox360 and PS4 controller emulation. usbip-win2 driver is required for Switch 1 Joy-Cons/Pro Controller, Switch 2 Pro Controller, and PS5/DualSense (with audio haptics) controller emulation.
    • Auto-Installation: The app will automatically detect if the selected driver (WinUHid, ViGEmBus, or USBIP) is missing and guide you through a one-click installation (requires administrator privileges) or open the download link for ViGEmBus.

ESP32-S3 N16R8 Guide
  • ESP32-S3 N16R8 Firmware Installation Guide:
  1. Hold the boot button on the ESP32-S3 N16R8 board.
  2. Plug in the ESP32-S3 N16R8 board's OTG port via USB-C to the PC while holding the boot button.
  3. In the app, click the [ESP32-S3 N16R8 Driver] button.
  4. Click click [Install] and wait until finish installing.
  5. Unplug and plug the ESP32-S3 N16R8 board.
  6. Reconnect any controllers previously paired via the system BLE by pressing SYNC.
  • ESP32-S3 N16R8 Buying Guide:
  1. Search for development boards strictly labeled as ESP32-S3 N16R8. This ensures the board contains 16MB Flash and 8MB PSRAM, which is necessary for handling complex tasks and controller connections. Avoid any boards labeled as "N8R2", "N8R8", or standard "ESP32".
  2. Select the ESP32-S3-WROOM-1 version if you want a built-in PCB antenna. This is the recommended, plug-and-play choice for standard plastic enclosures. Only choose the ESP32-S3-WROOM-1U version if you are using a metal case or require an external antenna to extend the Bluetooth/Wi-Fi range.
  3. Verify that the board features an OTG USB port (often a dual USB-C design). The OTG port is strictly required for data transfer and firmware installation.
