BlueR — Official BlueZ Bindings for Rust
This library provides the official Rust interface to the Linux Bluetooth protocol stack (BlueZ). Both publishing local and consuming remote GATT services using idiomatic Rust code is supported. L2CAP and RFCOMM sockets are presented using an API similar to Tokio networking.
This library depends on the tokio asynchronous runtime.
The following functionality is provided.
- Bluetooth adapters
- enumeration
- configuration of power, discoverability, name, etc.
- hot-plug support through change events stream
- Bluetooth devices
- discovery
- querying of address, name, class, signal strength (RSSI), etc.
- Bluetooth Low Energy advertisements
- change events stream
- connecting and pairing
- consumption of remote GATT services
- GATT service discovery
- read, write and notify operations on characteristics
- read and write operations on characteristic descriptors
- optional use of low-overhead AsyncRead and AsyncWrite streams for notify and write operations
- publishing local GATT services
- read, write and notify operations on characteristics
- read and write operations on characteristic descriptors
- two programming models supported
- callback-based interface
- low-overhead AsyncRead and AsyncWrite streams
- sending Bluetooth Low Energy advertisements
- Bluetooth authorization agent
- efficient event dispatching
- not affected by D-Bus match rule count
- O(1) in number of subscriptions
- L2CAP sockets
- support for both classic Bluetooth (BR/EDR) and Bluetooth LE
- stream oriented
- sequential packet oriented
- datagram oriented
- async IO interface with AsyncRead and AsyncWrite support
- RFCOMM sockets
- support for classic Bluetooth (BR/EDR)
- stream oriented
- async IO interface with AsyncRead and AsyncWrite support
- database of assigned numbers
- manufacturer ids
- services classes, GATT services, characteristics and descriptors
Currently, some classic Bluetooth (BR/EDR) functionality is missing. However, pull requests and contributions are welcome!
Crate features
The following crate features are available.
bluetoothd
: Enables all functions requiring a running Bluetooth daemon.id
: Enables database of assigned numbers.l2cap
: Enables L2CAP sockets.rfcomm
: Enables RFCOMM sockets.serde
: Enables serialization and deserialization of some data types.
To enable all crate features specify the full
crate feature.
Basic usage
Create a Session using Session::new; this establishes a connection to the Bluetooth daemon. Then obtain a Bluetooth adapter using Session::adapter. From there on you can access most of the functionality using the methods provided by Adapter.
L2CAP and RFCOMM sockets
Refer to the l2cap and rfcomm modules. No Session and therefore no running Bluetooth daemon is required.
