WD Cable creates a private local link between nearby devices using Wi-Fi Direct. Once connected, the devices share one app session for chat, file transfer, speed testing, and audio.

No internet, router, hotspot, account, or cloud service is required. The connection stays local between the participating devices.

Features:

Direct device-to-device connection over Wi-Fi Direct.
High-speed local file transfer.
Real-time chat between connected peers.
Protocol v2 transport setup with UDP rendezvous and detailed diagnostics.
Low-latency Audio Link using RTP/RTCP over UDP with libopus.
Selectable sender audio quality and latency modes.
Built-in upload and download speed tests.

The Android app can connect to another Android device running WD Cable. A separate Windows companion client is also available for Android-to-Windows workflows, including using an Android device as a local microphone sender.

Version 2.0.1 uses Protocol v2 and is not compatible with Protocol v1 builds. Both devices must run WD Cable 2.0.1 or another Protocol v2-compatible build.

Requires Android 13 or newer. Release APKs support arm64-v8a and x86_64 devices; 32-bit armeabi-v7a devices are not supported.

WD Cable is designed for offline peer-to-peer experiments, local transfer, quick device-to-device testing, and private nearby sharing.

WhatsNew:

New in 2.0.1:
- Protocol v2 connection setup for more reliable Wi-Fi Direct sessions.
- Fixed Windows endpoint routing issues caused by stale 192.168.137.1 adapters.
- Upgraded Audio Link to lower-latency RTP/RTCP streaming with libopus.
- Added audio latency modes, quality presets, and richer live audio stats.
- Protocol v1 builds are no longer compatible with this release.

Download Metadata Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
