# @ohos.distributedHardware.deviceManager (设备管理)(系统接口)

本模块能力已更新至新模块。建议使用新模块的接口进行开发，参见[@ohos.distributedDeviceManager](js-apis-distributedDeviceManager.md)。

本模块提供分布式设备管理能力。

系统应用可调用接口实现如下功能：

- 注册和解除注册设备上下线变化监听
- 发现周边不可信设备
- 认证和取消认证设备
- 查询可信设备列表
- 查询本地设备信息，包括设备名称，设备类型和设备标识
- 发布设备发现

> **说明：**
>
> - 本模块首批接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
> - 本模块为系统接口，三方应用不支持调用。


## 导入模块

```ts
import deviceManager from '@ohos.distributedHardware.deviceManager';
```


## deviceManager.createDeviceManager

createDeviceManager(bundleName: string, callback: AsyncCallback<DeviceManager>): void

创建一个设备管理器实例。

> 从API version 11 开始废弃。建议使用[deviceManager.createDeviceManager](js-apis-distributedDeviceManager.md#devicemanagercreatedevicemanager)替代。
