hap-ble

A Bluetooth LE transport for the hap-rust HomeKit controller stack. Discover, pair with, read from, and stream events off a HomeKit accessory over BLE, reusing the same Pair Setup / Pair Verify crypto as the IP transport.

Status: Milestone A — a standalone transport. Unifying it with the IP hap-controller under one API is Milestone B. Characteristic write, broadcast notifications, and Thread are out of scope for this milestone.

Example

use std::time::Duration;

# async fn run() -> Result<(), Box<dyn std::error::Error>> {
let found = hap_ble::scan(Duration::from_secs(5)).await?;
let Some(target) = found.iter().find(|a| !a.paired) else { return Ok(()) };

let gatt = hap_ble::connect_gatt(target).await?;
let controller = hap_ble::BleController::generate("my-controller".into());
let (accessory, _pairing) = controller.pair(gatt, target, "123-45-678").await?;

for acc in accessory.accessories() {
    println!("accessory with {} services", acc.services.len());
}
# Ok(())
# }

Platform notes

• macOS: uses CoreBluetooth; the first run triggers the system Bluetooth permission prompt.
• Linux: uses BlueZ over D-Bus.
