Public Functions

QBluetoothDeviceInfo ()

Constructs an invalid QBluetoothDeviceInfo object.

QBluetoothDeviceInfo (

Constructs a QBluetoothDeviceInfo object with Bluetooth address address, device name name and the encoded class of device classOfDevice.

The classOfDevice parameter is encoded in the following format

Bits Size Description 0 - 1 2 Unused, set to 0. 2 - 7 6 Minor device class. 8 - 12 5 Major device class. 13 - 23 11 Service class.

QBluetoothDeviceInfo (

Constructs a QBluetoothDeviceInfo that is a copy of other.

~QBluetoothDeviceInfo ()


QBluetoothAddress address ()

Returns the address of the device.

bool isCached ()

Returns true if the QBluetoothDeviceInfo object is created from cached data.

bool isValid ()

Returns true if the QBluetoothDeviceInfo object is valid, otherwise returns false.

MajorDeviceClass majorDeviceClass ()

Returns the major device class of the device.

QByteArray manufacturerSpecificData (
  • bool *available)

Returns the manufacturer specific data.

If available is not 0 it is set to true if manufacturer specific data is available; otherwise it is set to false.

Unsupported on all platforms at this time. Always return QByteArry();

quint8 minorDeviceClass ()

Returns the minor device class of the device.

QString name ()

Returns the name assigned to the device.

QBluetoothDeviceInfo & operator= (

Makes a copy of the other and assigns it to this QBluetoothDeviceInfo object.

bool operator== (

Returns true if the other QBluetoothDeviceInfo object and this are identical.

qint16 rssi ()

Returns the signal strength when the device was last scanned.

ServiceClasses serviceClasses ()

Returns the service class of the device.

QList< QBluetoothUuid > serviceUuids (

Returns the list of service UUIDS supported by the device.

If completeness is not 0 it will be set to DataComplete if the returned list is the complete list of UUIDs supported by the device. DataIncomplete if additional service UUIDs are supported by the device and DataUnavailable if no service UUID information is available.

This function requires both Bluetooth devices to support the 2.1 specification.

DataCompleteness serviceUuidsCompleteness ()

Returns the completeness of the service UUID list.

If DataComplete is returned then serviceUuids() will return a complete list of service UUIDs supported by the device. Otherwise serviceUuids() will only return a partial or empty list of service UUIDs. To get a full list of services supported by the device a full service discovery needs to be performed.

void setCached (
  • boolcached)

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 a live device.

void setManufacturerSpecificData (

Sets the manufacturer specific data returned by Extended Inquiry Responses to data.

Unsupported on all platforms at this time.

void setRssi (
  • qint16signal)

Set the signal strength value, used internally.

void setServiceUuids (

Sets the list of service UUIDs to uuids and the completeness of the data to completeness.
