| * Library * |
| **************************************************************************** |
| |
| QtBluetooth |
| ----------- |
| |
| - Added various improvements to the existing Bluetooth examples. |
| - Added various documentation improvements. |
| - Added new heartrate-game example replacing the old heartlistener example. |
| |
| QtNfc |
| ----- |
| |
| - Introduced QNearFieldTarget::maxCommandLength() to make it possible to |
| check the maximum supported length for commands. |
| - Introduced QNearFieldTarget::(set)keepConnection() permitting control over |
| the connection behavior. If this flag is set the NFC device does not disconnect |
| automatically after reading an NFC message. QNearFieldTarget::disconnect() |
| was added to permit manual separation of the connection. This feature is currently |
| only implemented on Android. |

| * Platform Specific Changes * |
| **************************************************************************** |
| |
| Android |
| ------- |
| |
| - Added support for QNearFieldTarget::sendCommand(). |
| - Fixed crash due to references leak in QBluetoothDeviceDiscoveryAgent on Android. |
| - Added more detailed GATT error reporting. |
| - [QTBUG-58085] Fixed unnecessarily dangerous right request for ACCESS_COURSE_LOCATION |
| during BTLE scanning on Android platforms below version 23. |
| - Prevented nil exception if reading of a descriptor failed during discovery. |
| - [QTBUG-58056] Fixed not reported characteristic if system failed to read its value |
| during the service discovery. |
| - [QTBUG-53483] Added support for BTLE peripheral on Android. |
| - [QTBUG-56078] Improved likelyhood that BluetoothGatt.connectGatt() succeeds. This addresses |
| the GATT_ERROR 133 (0x85) problem on Android v23+ devices. There is no fix available |
| on older Android versions. |
| - [QTBUG-57646] Fixed problems when using QtNfc when running as a service. |
| - [QTBUG-59343] Fixed crash on restart of NFC applications. |
| - [QTBUG-59455] Fixed detection of all NFC tags even non-NDEF tags. |
| - [QTBUG-59917] Added workaround for BLUETOOTH_PRIVILEGED security exception when |
| attempting to read a BTLE HID service. |
| |
| iOS/macOS |
| --------- |
| |
| - Fixed missing behavior whereby QLowEnergyController::disconnectFromDevice() |
| did not stop advertisement. |
| - [QTBUG-58080] Changed priority of advertised BTLE device name. Qt prefers the |
| device name as set by the advertisement data over the GAP name. |
| |
| Linux/BlueZ |
| ----------- |
| |
| - [QTBUG-52692] Prevented stalling of Linux central BTLE implementation. |
| - Fixed continued advertisement of peripheral data once |
| QLowEnergyController::disconnectFromDevice() was called. Public documentation |
| was added to publically state the behavior. |
| - [QTBUG-57417] Fixed duplicated QBluetoothLocalAdapter:deviceConnected() and |
| deviceDisconnected() signal emissions if the local device has several Bluetooth adapter. |
| - [QTBUG-59392] Ensured that pairing passkey and pincode are truly random. |
| - [QTBUG-59754] Ensured that QLowEnergyController::connected() is emitted on peripheral. |
| Previously the signal was never emitted. |
| |
| WinRT |
| ----- |
| |
| - [QTBUG-37779] Added support for Classic Bluetooth on WinRT. |
