Detailed Description#

QBluetoothServiceInfo provides information about a service offered by a Bluetooth device. In addition it can be used to register new services on the local device. Note that such a registration only affects the Bluetooth SDP entries. Any server listening for incoming connections (e.g an RFCOMM server) must be started before registerService() is called. Deregistration must happen in the reverse order.

QBluetoothServiceInfo is not a value type in the traditional sense. All copies of the same service info object share the same data as they do not detach upon changing them. This ensures that two copies can (de)register the same Bluetooth service.

On iOS, this class cannot be used because the platform does not expose an API which may permit access to QBluetoothServiceInfo related features.

class PySide6.QtBluetooth.QBluetoothServiceInfo#

PySide6.QtBluetooth.QBluetoothServiceInfo(other)

Parameters:

other – PySide6.QtBluetooth.QBluetoothServiceInfo

Construct a new invalid QBluetoothServiceInfo ;

Construct a new QBluetoothServiceInfo that is a copy of other.

The two copies continue to share the same underlying data which does not detach upon write.

The service must be unregistered and registered again with the changes.

The localAdapter parameter determines the local Bluetooth adapter under which the service should be registered. If localAdapter is null the default Bluetooth adapter will be used.
