Description Justin Zobel 2023-08-02 04:58:54 UTC

1. Open "Add Bluetooth Device" connection box 
2. See no devices
3. Check bluetoothctl from a terminal
4. See devices available for pairing

Comment 1 Nate Graham 2023-08-02 13:47:45 UTC

Can reproduce.

Comment 2 Kai Uwe Broulik 2023-08-04 15:00:02 UTC

Console prints:
qt.dbus.integration: Could not connect "org.freedesktop.DBus.ObjectManager" to "InterfacesAdded"

Comment 3 Nicolas Fella 2023-08-20 19:19:51 UTC

> 4. See devices available for pairing

You mean *now* you see devices *in the wizard*?

Comment 4 Justin Zobel 2023-08-21 01:55:25 UTC

I probably should have written:
4. Check devices available for pairing
5. See none

Message seems relevant.

With https://codereview.qt-project.org/c/qt/qtbase/+/502613 I get

qt.dbus.integration: Could not connect "org.freedesktop.DBus.ObjectManager" to interfacesAdded(const QDBusObjectPath &, const QVariantMapMap &) : "Unregistered input type in parameter list: QVariantMapMap"
