Blink the Pico onboard LED at 1 Hz when the connected DualSense reports PowerPercent <= 1 (i.e. <= 10%) and PowerState == Discharging. Source data is byte 52 of the BT 0x31 input report, already copied into interrupt_in_data; no new BT parsing required. The new module owns the LED only while it is actively blinking; it detects controller disconnection via stale-report timeout and steps out, so bt.cpp's existing connect/disconnect LED handling stays in charge in all other states. Honors disable_pico_led. Gated by -DENABLE_BATT_LED=ON (default). With the option off, the source file is not compiled and behavior is identical to upstream. CI gains a compile-only check for the OFF flavor. (cherry picked from commit 2f8ea73c9fb695e24e7cc3329db7cb925e82e1c9)

Pico2W DualSense 5 Bridge
Turn a Raspberry Pi Pico2W into a wireless adapter for the DualSense (DS5) controller.
Overview
This project enables the Raspberry Pi Pico2W to function as a Bluetooth bridge for the DualSense controller, allowing wireless connectivity with enhanced haptics support.
Features
- 🎮 Full DualSense connectivity via Pico2W
- 🔊 Supports HD haptics (advanced vibration feedback)
- 📡 Wireless Bluetooth bridging
- ⚙️ Adjustable haptic gain via microphone volume
- 🔕 Configurable LED and disconnection behaviors
Getting Started
Flashing Firmware
- Hold the BOOTSEL button on the Pico2W
- Connect the Pico2W to your computer via USB
- The device will mount as a USB storage device
- Drag and drop the .uf2 firmware file onto the device
Pairing the Controller
- Put the DualSense controller into Bluetooth pairing mode
- Wait for the Pico2W to detect and connect
- Once connected, the device will appear on the host system
Configuration
The following controller settings are repurposed:
Microphone volume
Controls haptic gain multiplier
Range: [1.0 – 2.0]
Speaker mute
Disables LED connection indicator
Takes effect after controller reconnects
Microphone mute
Disables silent disconnection behavior
Notes
The Pico device will only be visible to the system after the controller is connected
Some behaviors depend on reconnection cycles to take effect
Low-battery LED indicator
When the connected DualSense reports its battery at or below 10% (and it is not charging), the Pico onboard LED switches from solid-on to a 1 Hz blink so you can see the warning at a glance. The LED returns to solid-on as soon as the controller is plugged in or its reported level rises again. The indicator respects the existing disable_pico_led setting (Speaker mute toggle).
To opt out at build time, configure with -DENABLE_BATT_LED=OFF. Default is ON.
Known Issues
- ⚠️ Audio may experience slight stuttering
- ⚠️ Overclocking is required for proper performance
Performance / Overclocking
Due to encoding requirements, the Pico2W must be overclocked:
Current settings:
- Voltage: 1.2V
- Frequency: 320 MHz
If your device fails to boot:
- Increase voltage slightly or Reduce CPU frequency
Build Instructions
To build the project from source:
- Update TinyUSB in the Pico SDK to the latest version
- Compile using standard Pico SDK toolchain
