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 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
  • android.permission.ACCESS_FINE_LOCATION

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

注意： Currently on Android the android.permission.ACCESS_FINE_LOCATION permission is requested together with Bluetooth permissions. This is required for Bluetooth to work properly, unless the application provides a strong assertion in the application manifest that it does not use Bluetooth to derive a physical location. This permission coupling may change in future.

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.

注意： For now the Access mode on Android also requests the precise location permission. This permission coupling may change in the future.

This enum was introduced in Qt 6.6.

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。

该函数在 Qt 6.6 引入。
