BlueZ异步客户端

bluez-async 是 BlueZ（Linux蓝牙守护进程）的D-Bus接口的异步包装器。它提供了类型安全的接口，用于BlueZ暴露的蓝牙客户端（即中心，在蓝牙术语中）接口的子集，专注于蓝牙低能耗（BLE）的通用属性配置文件（GATT）。

用法

// Create a new session. This establishes the D-Bus connection to talk to BlueZ. In this case we
// ignore the join handle, as we don't intend to run indefinitely.
let (_, session) = BluetoothSession::new().await?;

// Start scanning for Bluetooth devices, and wait a few seconds for some to be discovered.
session.start_discovery().await?;
time::sleep(Duration::from_secs(5)).await;
session.stop_discovery().await?;

// Get a list of devices which are currently known.
let devices = session.get_devices().await?;

// Find the device we care about.
let device = devices
    .into_iter()
    .find(|device| device.name.as_deref() == Some("My device"))
    .unwrap();

// Connect to it.
session.connect(&device.id).await?;

// Look up a GATT service and characteristic by short UUIDs.
let service = session
    .get_service_by_uuid(&device.id, uuid_from_u16(0x1234))
    .await?;
let characteristic = session
    .get_characteristic_by_uuid(&service.id, uuid_from_u32(0x1235))
    .await?;

// Read the value of the characteristic and write a new value.
println!(
    "Value: {:?}",
    session
        .read_characteristic_value(&characteristic.id)
        .await?
);
session
    .write_characteristic_value(&characteristic.id, vec![1, 2, 3])
    .await?;

// Subscribe to notifications on the characteristic and print them out.
let mut events = session
    .characteristic_event_stream(&characteristic.id)
    .await?;
session.start_notify(&characteristic.id).await?;
while let Some(event) = events.next().await {
    if let BluetoothEvent::Characteristic {
        id,
        event: CharacteristicEvent::Value { value },
    } = event
    {
        println!("Update from {}: {:?}", id, value);
    }
}
