[since 5.5]
QBluetoothDeviceInfo::
QBluetoothDeviceInfo
(const
QBluetoothUuid
&
uuid
, const
QString
&
name
,
quint32
classOfDevice
)
Constructs a QBluetoothDeviceInfo object with unique uuid , device name name and the encoded class of device classOfDevice .
This constructor is required for Low Energy devices on macOS and iOS. CoreBluetooth API hides addresses and provides unique UUIDs to identify a device. This UUID is not the same thing as a service UUID and is required to work later with CoreBluetooth API and discovered devices.
该函数在 Qt 5.5 引入。
Constructs a QBluetoothDeviceInfo object with Bluetooth address address , device name name and the encoded class of device classOfDevice .
classOfDevice parameter is encoded in the following format
| Bits | Size | 描述 |
|---|---|---|
| 0 - 1 | 2 | Unused, set to 0. |
| 2 - 7 | 6 | Minor device class. |
| 8 - 12 | 5 | Major device class. |
| 13 - 23 | 11 | Service class. |
Constructs an invalid QBluetoothDeviceInfo object.
Makes a copy of the other 并将其赋值给此 QBluetoothDeviceInfo 对象。
销毁 QBluetoothDeviceInfo .
Returns the address of the device.
注意： On iOS and macOS this address is invalid. Instead deviceUuid () should be used. Those two platforms do not expose Bluetooth addresses for found Bluetooth devices and utilize unique device identifiers.
另请参阅 deviceUuid ().
[since 5.4]
QBluetoothDeviceInfo::CoreConfigurations
QBluetoothDeviceInfo::
coreConfigurations
() const
Returns the configuration of the device. If device configuration is not set, basic rate device configuration will be returned.
该函数在 Qt 5.4 引入。
另请参阅 setCoreConfigurations ().
[since 5.5]
QBluetoothUuid
QBluetoothDeviceInfo::
deviceUuid
() const
Returns a unique identifier for a Bluetooth device without an address.
In general, this uuid is invalid on every platform but macOS and iOS. It is used as a workaround for those two platforms as they do not provide Bluetooth addresses for found Bluetooth Low Energy devices. Every other platform uses address () 代替。
该函数在 Qt 5.5 引入。
另请参阅 setDeviceUuid ().
返回 true 若 QBluetoothDeviceInfo object is created from cached data.
返回 true 若 QBluetoothDeviceInfo object is valid, otherwise returns false.
Returns the major device class of the device.
[since 5.12]
QByteArray
QBluetoothDeviceInfo::
manufacturerData
(
quint16
manufacturerId
) const
Returns the data associated with the given manufacturerId .
Manufacturer data is defined by the Supplement to the Bluetooth Core Specification and consists of two segments:
The interpretation of the data octets is defined by the manufacturer specified by the company identifier.
注意： The remote device may provide multiple data entries per manufacturerId. This function only returns the first entry. If all entries are needed use manufacturerData () which returns a multi hash.
该函数在 Qt 5.12 引入。
另请参阅 manufacturerIds () 和 setManufacturerData ().
[since 5.12]
QMultiHash
<
quint16
,
QByteArray
> QBluetoothDeviceInfo::
manufacturerData
() const
Returns the complete set of all manufacturer data.
Some devices may provide multiple manufacturer data entries per manufacturer ID. An example might be a Bluetooth Low Energy device that sends a different manufacturer data via advertisement packets and scan response packets respectively. Therefore the returned hash table may have multiple entries per manufacturer ID or hash key.
该函数在 Qt 5.12 引入。
另请参阅 setManufacturerData .
[since 5.12]
QList
<
quint16
> QBluetoothDeviceInfo::
manufacturerIds
() const
Returns all manufacturer ids attached to this device information.
该函数在 Qt 5.12 引入。
另请参阅 manufacturerData () 和 setManufacturerData ().
Returns the minor device class of the device. The actual information is context dependent on the value of majorDeviceClass ().
另请参阅 MinorAudioVideoClass , MinorComputerClass , MinorHealthClass , MinorImagingClass , MinorMiscellaneousClass , MinorNetworkClass , MinorPeripheralClass , MinorPhoneClass , MinorToyClass ，和 MinorWearableClass .
Returns the name assigned to the device.
另请参阅 setName ().
Returns the signal strength when the device was last scanned
另请参阅 setRssi ().
Returns the service class of the device.
[since 6.0]
QList
<
QBluetoothUuid
> QBluetoothDeviceInfo::
serviceUuids
() const
Returns the list of service UUIDS supported by the device. Most commonly this list of uuids represents custom uuids or a uuid value specified by QBluetoothUuid::ServiceClassUuid .
该函数在 Qt 6.0 引入。
另请参阅 setServiceUuids () and serviceUuids().
Used by the system to set the cached flag if the QBluetoothDeviceInfo is created from cached data. Cached information may not be as accurate as data read from an active device.
另请参阅 isCached ().
[since 5.4]
void
QBluetoothDeviceInfo::
setCoreConfigurations
(
QBluetoothDeviceInfo::CoreConfigurations
coreConfigs
)
设置 CoreConfigurations 为设备到 coreConfigs . This will help to make a difference between regular and Low Energy devices.
该函数在 Qt 5.4 引入。
另请参阅 coreConfigurations ().
[since 5.5]
void
QBluetoothDeviceInfo::
setDeviceUuid
(const
QBluetoothUuid
&
uuid
)
Sets the unique identifier uuid for Bluetooth devices, that do not have addresses. This happens on macOS and iOS, where the CoreBluetooth API hides addresses, but provides UUIDs to identify devices/peripherals.
This uuid is invalid on any other platform.
该函数在 Qt 5.5 引入。
另请参阅 deviceUuid ().
[since 5.12]
bool
QBluetoothDeviceInfo::
setManufacturerData
(
quint16
manufacturerId
, const
QByteArray
&
data
)
Sets the advertised manufacturer
data
为给定
manufacturerId
。返回
true
if it was inserted,
false
if it was already known.
Since Qt 5.14, different values for data and the same manufacturerId no longer replace each other but are accumulated for the duration of a device scan.
该函数在 Qt 5.12 引入。
另请参阅 manufacturerData .
[since 6.2]
void
QBluetoothDeviceInfo::
setName
(const
QString
&
name
)
设置 name 为设备。
该函数在 Qt 6.2 引入。
另请参阅 name ().
