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.

|
||
|
|
- Added more detailed GATT error reporting.
|
||
|
|
- [QTBUG-58085] Fixed unnecessarily dangerous right request for ACCESS_COURSE_LOCATION
|
