What is the Si-Leer library?

Si-Leer is a library for working with Bluetooth Low Energy (BLE) in iOS applications, providing a higher-level and more abstract API compared to the native Core Bluetooth framework. It simplifies tasks such as device scanning, connecting, service and characteristic discovery, and data reading and writing.

Key features of Si-Leer:

• Simplified API: Abstracts away the complexity of Core Bluetooth, making the code more readable and maintainable.
• Reactive approach: Uses reactive programming (usually via RxSwift or Combine), providing data streams for BLE events (discovered devices, connection state changes, etc.).
• Automatic lifecycle management: Manages device connection and disconnection, subscriptions to characteristics.
• Error handling: Provides a structured way to handle BLE errors.
• Type safety: Allows typing of data transmitted through characteristics.

Example of device scanning using Si-Leer (RxSwift):

import Si_Leer // assuming the library is imported this way
import RxSwift
import CoreBluetooth // still needed for CBService/CBCharacteristic UUIDs

let disposeBag = DisposeBag()
let centralManager = CentralManager(queue: .main) // Initialization

centralManager.scanForPeripherals(withServices: nil) // Scanning all devices
    .subscribe(onNext: { peripheral in
        print("Discovered device: \(peripheral.peripheral.name ?? "Unknown")")
    }, onError: { error in
        print("Scanning error: \(error)")
    })
    .disposed(by: disposeBag)

Si-Leer is suitable for projects that require a more understandable and reactive approach to working with BLE, especially in conjunction with other reactive frameworks. It reduces boilerplate code compared to pure Core Bluetooth.
