Receive and accept connection invitations directly from an Android device.

What's New in 2.0.1

Version 2.0.1 is the Protocol v2 release. It separates Wi-Fi Direct group-owner/client roles from WDCable TCP listener/connector roles, uses UDP rendezvous when needed, and improves diagnostics for transport setup and handshake failures.

Audio Link now uses RTP/RTCP over UDP with libopus for lower-latency streaming. Senders can choose from Standard (32 kbps), Balanced (64 kbps), High (128 kbps), and Near lossless (256 kbps) quality presets, along with Low latency and Stable latency modes.

✨ Features

• Connect without network infrastructure — Link nearby devices directly over Wi-Fi Direct, with no router, hotspot, or internet connection required.
• Transfer files quickly — Send files between Windows and Android with drag-and-drop support and a clear transfer history.
• Chat across devices — Exchange messages with a connected device over the same direct connection.
• Stream audio with Audio Link — Send Windows system audio to Android or stream Android microphone audio to Windows using low-latency RTP/RTCP and Opus encoding, with selectable quality and latency modes.
• Measure connection performance — Run a built-in speed test to check the quality and throughput of the direct link.
• Use a native Windows experience — Work in a modern WinUI 3 interface designed for Windows 10 and Windows 11.

🔗 How It Works

WDCable uses Wi-Fi Direct to establish a peer-to-peer connection between supported devices. Protocol v2 assigns the WDCable TCP listener to the Wi-Fi Direct client and uses UDP rendezvous when necessary to discover the peer endpoint safely. Data travels directly between the devices instead of passing through a router or the internet.

💻 Requirements

• Windows 10 version 1809 (build 17763) or later, or Windows 11.
• An x64 or ARM64 Windows device.
• A Wi-Fi network adapter and driver that support Wi-Fi Direct.
• A second compatible Windows or Android device for peer-to-peer communication.
