The bluetoothManager module provides Bluetooth management capabilities, including setting and obtaining Bluetooth information.

NOTE

The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The APIs of this module can be used only in the stage model.

The APIs of this module can be called only by a device administrator application that is enabled.

The global restriction policies are provided by restrictions. To disable Bluetooth globally, see @ohos.enterprise.restrictions.

Modules to Import

import { bluetoothManager } from '@kit.MDMKit';

bluetoothManager.getBluetoothInfo

getBluetoothInfo(admin: Want): BluetoothInfo

Obtains device Bluetooth information.

Required permissions: ohos.permission.ENTERPRISE_MANAGE_BLUETOOTH

System capability: SystemCapability.Customization.EnterpriseDeviceManager

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	EnterpriseAdminExtensionAbility.

Return value

Type	Description
BluetoothInfo	Bluetooth information, including the Bluetooth name, state, and profile connection state.

Error codes

For details about the error codes, see Enterprise Device Management Error Codes and Universal Error Codes.

ID	Error Message
9200001	The application is not an administrator application of the device.
9200002	The administrator application does not have permission to manage the device.
201	Permission verification failed. The application does not have the permission required to call the API.
401	Parameter error. Possible causes: 1. Mandatory parameters are left unspecified; 2. Incorrect parameter types; 3. Parameter verification failed.

Example

import { Want } from '@kit.AbilityKit';
import { bluetoothManager } from '@kit.MDMKit';
let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};

try {
    let result: bluetoothManager.BluetoothInfo = bluetoothManager.getBluetoothInfo(wantTemp);
    console.info(`Succeeded in getting bluetooth info: ${JSON.stringify(result)}`);
} catch(err) {
    console.error(`Failed to get bluetooth info. Code: ${err.code}, message: ${err.message}`);
}

bluetoothManager.addAllowedBluetoothDevices
