Hi,
With the risk of being totally wrong (I'm not really into DBus): according to
the DbusInterface example in this page: Nemo Mobile D-Bus QML Plugin — Nemo
Mobile D-Bus QML Plugin 2.0.0 documentation, you should set signalsEnabled =
true.

Hi,
I'm trying to listen to the MCE DBUS API for changes from the display and the
radios.
For some reason, I won't receive the signals while writing on the /request
endpoint works perfectly.
Someone an idea?
Seems that Slava can make this work:
https://github.com/monich/harbour-lib/blob/master/src/HarbourSystemState.cpp
DBusInterface {
id: dbusFlight
bus: DBus.SystemBus
service: "com.nokia.mce"
path: "/com/nokia/mce/signal"
iface: "com.nokia.mce.signal"
// Signals
function radio_states_ind(state) {
console.log(JSON.stringify("MCE radio state= " + state))
}
function display_status_ind(state) {
console.log(JSON.stringify("MCE display state= " + state))
}
}
Cheers,
Dylan

Yes, in that respect the changes are backward compatible. Whatever you are
getting from GetProperties can be monitored by handling the PropertyChanged
signals. You just need to be prepared that SetProperty and other calls
(Connect, Disconnect etc.) may respond with net.connman.Error.PermissionDenied
if your process doesn't have enough privileges for that.
The idea is that the user has to be reasonably sure that a random app pulled
from Jolla Store doesn't mess with the system configuration (e.g. doesn't
enable mobile data behind your back). Most likely, a similar fate is awaiting
ofono and a few other D-Bus interfaces. Right now Jolla Store apps can do way
too much over D-Bus. We (well, at least I) will try not to not break backward
compatibility of D-Bus APIs except when the breakage is absolutely inevitable,
even though those are not officially supported APIs.
And as always, all these changes are open for close examination at
git.merproject.org.

Can I still monitor for changes and read properties? Can you give a more
complete view what will change exactly? I am building an universal bridge
between Python and QML with integrated Platform APIs based on DBUS and other
stuff.

And keep in mind that starting with Sailfish OS 2.1.1 non-privileged processes
won't be able to set this property (as well as do a few other connman things,
e.g. manipulate the services). In order to be able to use the restricted D-Bus
APIs you would have to ask the launcher to run your app under nemo:privileged
but that would automatically disqualify the app from getting accepted to Jolla
Store. Sailfish OS is getting security conscious!

You’re missing the property name. You need:
string:Powered variant:boolean:true
ref:
https://together.jolla.com/question/56437/i-would-like-to-toggle-internet-connectivity-via-terminal-with-dbus/
typedCall('SetProperty', [ {'type':'s', 'value': 'Powered'}, {'type':'v',
'value': valuet}], …);

Subject: [SailfishDevel] Nemo DBus typedCall
Hi devs,
I'm playing around with the Nemo DBus QML plugin but I'm a little bit stuck
when using the function typedCall().
DBusInterface {
id: wifi
bus: DBus.SystemBus
service: 'net.connman'
path: '/net/connman/technology/wifi'
iface: 'net.connman.Technology'
signalsEnabled: true
function setState(powered) {
var value = powered? 'true': 'false'
typedCall('SetProperty',
{'type':'s', 'value':value},
function() { console.log('[INFO] wifi power state set') },
function() { console.log('[ERROR] wifi power state
failed') })
}
function propertyChanged(name, value) {
console.log("WiFi changed NAME=%1 VALUE=%2".arg(name).arg(value))
}
}
But it seems that I'm doing something wrong when I try to enable/disable wifi.
It's my first attempts with DBus but I have managed to read the signals with
the plugin without any issues.
Cheers,
Dylan
