I found the issue
You have to connect to the systemBus not to the sessionBus!
if (QDBusConnection::systemBus().connect("de.pengutronix.rauc", =
//Service
"/", //Path
"org.freedesktop.DBus.Properties", //Inter=
face
"PropertiesChanged",
this,
SLOT(propertyChanged(const QString& ,
const QMap<QString, Q=
Variant>& ,
const QStringList& ))=
)) {
qDebug() << "PropertiesChanged signal connected successfully to slo=
t";
} else {
qDebug() << "PropertiesChanged signal connection was not successful=
";
}
Now I my function propertyChanged is called every time the property changes=
.
If you use

Hi Euen,
I know but I am stucking. I am polling the propery "Operation". Just when i=
t changes from "idle" to "installing" I subscribe the PropertiesChanged sig=
nal but without success. I tried several connect strings but all without su=
ccess.
if (QDBusConnection::sessionBus().connect("de.pengutronix.rauc",
"/",
"org.freedesktop.DBus.Properties",
"PropertiesChanged",
this,
SLOT(propertyChanged(const QString& ,
const QMap<QString, Q=
Variant>& ,
const QStringList& ))=
))
{
qDebug() << "PropertiesChanged signal connected successfully to slot";
} else {
qDebug() << "PropertiesChanged signal connection was not successful";
}
Please can you tell me how to subcribe the PropertiesChanged signal?

Hi Michael,
you can connect to a property change on dbus level. That is the way we do i=
t.
