Hi Pierre, Please do not drop the CC, because someone else might also be interested in our discussion.

But sometimes this is what you want. Yes, the ncurses example avoids to pull in a lot of dependencies. But then you have to handle all the low level stuff yourself. That can be hard work. GDbus & friends do help to abstract a bit from the low level bits. But the price is that you have to follow the GDbus way. I can't really help you here, since you didn't tell us what you plan to do. If you just want to monitor some signals from ConnMan, e.g. offline/online, then you might take a short cut. But be aware you need to handle all the async DBus messages, which means you need to have an event loop etc. That is why GDbus is not so a bad option, because you get all those low level handling done by the frameworks. Since you are really starting working with DBus I highly recommend to use a higher level framework. There are many really nasty pitfalls when it comes to DBus, especially libdbus. Again, I can't help you here, no idea what you are trying to do. Thanks, Daniel
