# DuooomiBleSDK (iOS)

纯原生 Swift BLE SDK，零第三方依赖。

## 集成

### CocoaPods

```ruby
pod 'DuooomiBleSDK', :git => 'https://gitea.bowong.cc/comi-logic/duooomi-ios-sdk.git', :branch => 'main'
```

然后执行 `pod install`。

### Swift Package Manager

```swift
// Package.swift
dependencies: [
    .package(url: "https://gitea.bowong.cc/comi-logic/duooomi-ios-sdk.git", branch: "main")
]
```

## 初始化

```swift
let sdk = DuooomiBleSDK(config: .init(
    apiKey: "your-api-key"                      // 必填
    // apiHost: URL(...)!,                      // 默认 https://api.duooomi.com
    // cdnHost: "https://cdn.bowong.cc/",       // 默认
    // firmwareIdentifier: "duomi",             // 默认
    // firmwareStatus: "DRAFT"                  // 默认
    // aniWidth: 360,                           // ANI 转换宽度，默认 360
    // aniHeight: 360,                          // ANI 转换高度，默认 360
    // aniFps: "24",                            // ANI 转换帧率，默认 24
))

// 设置代理接收状态变化
sdk.delegate = self
```

## 代理（Delegate）

通过 `DuooomiBleSDKDelegate` 接收状态变化，所有方法在主线程调用，均有默认空实现：

```swift
extension ViewController: DuooomiBleSDKDelegate {
    func sdk(_ sdk: DuooomiBleSDK, didChangeState state: ConnectionState) { }
    func sdk(_ sdk: DuooomiBleSDK, didUpdateDevices devices: [DiscoveredDevice]) { }
    func sdk(_ sdk: DuooomiBleSDK, didConnectDevice device: DiscoveredDevice?) { }
    func sdk(_ sdk: DuooomiBleSDK, didUpdateDeviceInfo info: DeviceInfo?) { }
    func sdk(_ sdk: DuooomiBleSDK, didUpdateVersion version: String) { }
    func sdk(_ sdk: DuooomiBleSDK, didChangeActivation isActivated: Bool) { }
    func sdk(_ sdk: DuooomiBleSDK, didUpdateProgress progress: Int) { }
    func sdk(_ sdk: DuooomiBleSDK, didEncounterError error: String?) { }
}
```

## API

所有异步方法使用 `completion` 回调，返回 `Result<T, Error>`。

### 扫描

| 方法 | 说明 |
|------|------|
| `scan()` | 开始扫描，结果通过 delegate `didUpdateDevices` 回调 |
| `stopScan()` | 停止扫描 |

### 连接

```swift
sdk.connect(deviceId: deviceId) { result in
    switch result {
    case .success(let device): print("Connected: \(device.name ?? device.id)")
    case .failure(let error): print("Failed: \(error)")
    }
}

sdk.disconnect { result in
    // ...
}
```

### 设备命令

```swift
sdk.getDeviceInfo { result in
    if case .success(let info) = result {
        print("Brand: \(info.brand), Power: \(info.powerlevel)%")
    }
}

sdk.getVersion { result in
    if case .success(let info) = result {
        print("Version: \(info.version)")
    }
}

sdk.bind(userId: "user-id") { result in
    if case .success(let resp) = result {
        print("SN: \(resp.sn), Files: \(resp.contents.count)")
    }
}

sdk.unbind(userId: "user-id") { result in /* ... */ }
sdk.deleteFile(key: "file-key") { result in /* ... */ }
```

### 文件传输

```swift
// 一步完成：格式校验 → ANI 转换 → prepare → transfer
sdk.transferMedia(fileUrl: "https://example.com/video.mp4") { result in
    switch result {
    case .success: print("Transfer complete")
    case .failure(let error): print("Transfer failed: \(error)")
    }
}
// 进度通过 delegate didUpdateProgress 回调
```

**支持的媒体格式：** JPEG、PNG、GIF、MP4、WebM、WebP

格式校验规则：
- 优先从 URL path 提取扩展名（自动忽略查询参数）
- 无扩展名时通过 HEAD 请求检查 `Content-Type`
- 不支持的格式返回 `DuooomiBleError.unsupportedFormat`

### 固件升级

```swift
// 1. 查询最新固件
sdk.fetchLatestFirmware { result in
    guard case .success(let info?) = result else { return }

    // 2. 检查是否有新版本
    let needUpdate = sdk.hasNewerFirmware(
        deviceVersion: sdk.version,
        serverVersion: info.version
    )

    // 3. OTA 升级
    if needUpdate {
        sdk.upgradeFirmware(fileUrl: info.fileUrl) { result in /* ... */ }
    }
}
```

### 可读取状态

| 属性 | 类型 | 说明 |
|------|------|------|
| `btState` | `ConnectionState` | idle / scanning / connecting / connected / disconnecting / disconnected |
| `discoveredDevices` | `[DiscoveredDevice]` | 扫描到的设备列表 |
| `connectedDevice` | `DiscoveredDevice?` | 当前连接设备 |
| `deviceInfo` | `DeviceInfo?` | 设备信息 |
| `version` | `String` | 固件版本 |
| `isActivated` | `Bool` | 是否已绑定 |
| `transferProgress` | `Int` | 传输进度 0-100 |
| `error` | `String?` | 最近错误 |

### 数据类型

```swift
// FirmwareInfo — fetchLatestFirmware 返回
public struct FirmwareInfo {
    let version: String      // 版本号
    let fileUrl: String      // 固件下载地址
    let description: String? // 描述
    let fileSize: String?    // 文件大小（字节字符串）
    let fileMd5: String?     // MD5 校验
    let identifier: String?  // 设备标识
    let status: String?      // DRAFT / PUBLISHED
}

// DeviceInfo — getDeviceInfo 返回
public struct DeviceInfo {
    let name: String         // 设备名
    let brand: String        // 品牌
    let size: String         // 屏幕尺寸
    let powerlevel: Int      // 电量百分比
    let allspace: UInt64     // 总存储（字节）
    let freespace: UInt64    // 可用存储（字节）
}

// BindingResponse — bind 返回
public struct BindingResponse {
    let success: Int         // 1=成功
    let sn: String           // 设备序列号
    let contents: [String]   // 设备文件 key 列表
}
```
