btleplug is an async Rust BLE library, supporting Windows 10, macOS, Linux, and iOS. It grew out of several earlier abandoned libraries for various platforms (rumble, blurmac, etc...), with the goal of building a fully cross platform library. Adding support for other platforms such as Android is planned.

btleplug is meant to be host/central mode only. If you are interested in peripheral BTLE (i.e. acting like a Bluetooth LE device instead of connecting to one), check out bluster.

This library DOES NOT SUPPORT BLUETOOTH 2/CLASSIC. There are no plans to add BT2/Classic support.

Note that as of v0.8, btleplug is now async, using tokio as a runtime. The API has changed drastically since 0.7, and no longer resembles rumble as much as it did before.

While we've done our best to test it, we expect there will be issues with this release. Please file issues as you find them and we will address them as soon as possible.

• Linux / Windows / macOS / iOS
  • Device enumeration and characteristic/services implemented and working.
  • Please file bugs and missing features if you find them.
• Android
  • Android implementation is in development.
  • Tracking issue here.
  • Please hold off on filing more issues until base implementation is landed.
• WASM/WebBluetooth
  • WebBluetooth is possible, and some work has happened.
  • Tracking issue here
  • Please hold off on filing more issues until base implementation is landed.

To use Bluetooth on macOS Big Sur (11) or later, you need to either package your binary into an application bundle with an Info.plist including NSBluetoothAlwaysUsageDescription, or (for a command-line application such as the examples included with btleplug) enable the Bluetooth permission for your terminal. You can do the latter by going to System Preferences → Security & Privacy → Privacy → Bluetooth, clicking the '+' button, and selecting 'Terminal' (or iTerm or whichever terminal application you use).

• X: Completed and released
• O: In development
• Blank: Not started

To enable implementation of serde's Serialize and Deserialize across some common types in the api module, use the serde feature.
