****************************************************************************
* Qt 5.12.0 Changes *
****************************************************************************
QtBluetooth
-----------
- [QTBUG-68026] Excluded ICC build for QtBluetooth. Previously, ICC attempted to build
the WinRT implementation which does not work. In the long term, ICC should build
the Win32 port of QtBluetooth which unfortunately does not exist yet.
- [QTBUG-68550] Added a DBus based Bluez implementation for QBluetoothSocket. Previously,
raw Bluetooth socket API was used to established the connection. However
this is no longer the recommended BlueZ way and hence the need for this change.
The new implementation is chosen if the BlueZ runtime version is 5.46+. This change
required extensive redesign of the QBluetoothSocket internals affecting all other platforms.
- [QTBUG-69857] Fixed crash in QBluetoothServiceInfo::unregisterService() on macOS.
- Added manufacturer data related API to QBluetoothDeviceInfo. This is needed for
Bluetooth Low Energy device scans.
- [QTBUG-46008] [QTBUG-69747] Added QBluetoothDeviceDiscoveryAgent::deviceUpdated()
signal. The signal permits live updates of changing Bluetooth Low Energy data such
as manufacturer or RSSI information during the discovery.
- Fixed incorrect QLowEnergyService::state() of local (peripheral) services.
- Fixed failing Bluetooth config test when using clang due to stricter error
dectection in clang (when compared to gcc).
- [QTBUG-70222] Fixed incorrect detection of BTLE Battery services in BlueZ 5.48+
- [QTBUG-70295] Added implementation to properly handle pin code pairing
(BluetoothDevice.PAIRING_VARIANT_PIN) on Android. So far, only
BluetoothDevice.PAIRING_VARIANT_PASSKEY_CONFIRMATION was supported.
- [QTBUG-70754] Ensured that repeated calls to QLowEnergyCOntroller::startAdvertising()
updates the to-be-updated info on Linux.
- [QTBUG-58660] Fixed discovery of unpaired Bluetooth devices on WinRT.
- [QTBUG-58529] Fixed incorrect BluetoothProfileDescriptorList generation by various
QBluetoothSocket related classes, documentation and examples.
QtNfc
-----
- [QTBUG-62169] Added QNearFieldManager::isSupported(). This only works on
Android at the moment.
- Added QNearFieldManager::AdapterState enum and the related adapterStateChanged()
signal.
