详细描述

要求

To request this permission at runtime, the following platform specific usage declarations have to be made at build time:

平台类型

Apple Usage description NSBluetoothAlwaysUsageDescription

Android

平台	类型
Apple	Usage description	`NSBluetoothAlwaysUsageDescription`
Android	`uses-permission`	Up to Android 11 (API Level < 31): `android.permission.BLUETOOTH` `android.permission.ACCESS_FINE_LOCATION` Starting from Android 12 (API Level >= 31): `android.permission.BLUETOOTH_ADVERTISE` `android.permission.BLUETOOTH_CONNECT` `android.permission.BLUETOOTH_SCAN`

uses-permission

Up to Android 11 (API Level < 31):

android.permission.BLUETOOTH
android.permission.ACCESS_FINE_LOCATION

Starting from Android 12 (API Level >= 31):

android.permission.BLUETOOTH_ADVERTISE
android.permission.BLUETOOTH_CONNECT
android.permission.BLUETOOTH_SCAN

Please see the individual usage declaration types for how to add them to your project.

注意： Since Qt 6.8.1, the ACCESS_FINE_LOCATION permission is no longer requested if API Level >= 31. This may limit some Bluetooth scan results . Users needing these results need to request the location permission separately (see precise location ) and ensure that BLUETOOTH_SCAN permission doesn't have the android:usesPermissionFlags="neverForLocation" attribute set. For setting and customizing permissions in the application manifest, see this guide .

成员类型文档编制

`[since 6.6]` enum QBluetoothPermission:: CommunicationMode
flags QBluetoothPermission:: CommunicationModes

This enum is used to control the allowed Bluetooth communication modes.

常量	值	描述
`QBluetoothPermission::Access`	`0x01`	Allow this device to access other Bluetooth devices. This includes scanning for nearby devices and connecting to them.
`QBluetoothPermission::Advertise`	`0x02`	Allow other Bluetooth devices to discover this device.
`QBluetoothPermission::Default`	`Access \| Advertise`	This configuration is used by default.

注意： The fine-grained permissions are currently supported only on Android 12 and newer. On older Android versions, as well as on Apple operating systems, any mode results in full Bluetooth access.

该枚举在 Qt 6.6 引入。

The CommunicationModes type is a typedef for QFlags <CommunicationMode>. It stores an OR combination of CommunicationMode values.

成员函数文档编制

`[since 6.6]` QBluetoothPermission::CommunicationModes QBluetoothPermission:: communicationModes () const

Returns the allowed Bluetooth communication modes.

该函数在 Qt 6.6 引入。

另请参阅 setCommunicationModes ().

`[since 6.6]` void QBluetoothPermission:: setCommunicationModes ( QBluetoothPermission::CommunicationModes modes )

Sets the allowed Bluetooth communication modes to modes .

注意： A default-constructed instance of CommunicationModes has no sense, so an attempt to set such a mode will raise a qWarning() and fall back to using the 默认模式。
