Qt C ++ BlueZ 5 QDbus库

Question

In BlueZ 5 the DBus API has changed substantially. I previously had a working QDbus controller library for BlueZ 4 based on this: https://gitorious.org/qt-bluez-demos/

I've been googling quite a bit and cannot find any existing starting point to convert my BlueZ 4 library to BlueZ 5.

NOTE: I'm using Qt 4.8 but it seems Qt 5.0 has some QBluetooth namespace, however it has not been updated for BlueZ 5 yet either:

https://bugreports.qt-project.org/browse/QTBUG-32085?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab

This library is also BlueZ 4 only:

Can anybody point me to some existing code? Thanks!

Answer 1

As the corresponding bug tracker entry writes:

The Bluez API has released a new major release which is incompatible to Bluez 4.x. Currently QtBluetooth supports Bluez 4.x only.

It means that, unfortunately. The bugreport is still open, and this has not been fixed yet. You will need patience or enough courage to step up and contribute to it.

Answer 2

BlueZ 5 support is now in Qt as of 5.4 . I arrived at this question because I'm creating some software for BLE devices using Qt 5.5 and I want to know how I can know if my Qt instance is in fact using BlueZ 5 or BlueZ 4.

https://github.com/KDE/bluez-qt上的KDE bluez-qt项目是BlueZ 5的基于Qt的包装器。与Qt蓝牙模块不同，该API相当直接地映射到BlueZ 5 D-Bus API。它自己的API，因此取决于您的需求。
