I've been digging info about connectivity API for Maemo, but I can't find solid examples and how stuff works. Yes, I'm quite new in C++, but I would like to write something like sync and backup program (it's my student work).

What I need to know:

- what API can I use for connection to N900 (USB - like Nokia suite, WiFi, BT) ?
I don't know enough about USB or BT connections, but if you're doing Wifi, then it will be like any other client/server or peer-to-peer utility: sockets.
Qt provides a tcp server convenience class and a tcp socket class to ease development.
There is a UDP class as well as a generic socket class.
Some examples of using these classes: Fortune Server Example, Fortune Client Example, Threaded Fortune Server Example, Blocking Fortune Client Example, Loopback Example, Torrent Example.

Shameless plug: You can also consider using mosquitto. It works on many platforms and I've recompiled and packaged it for Maemo.
My sig has the relevant links.

Maemo is a full fledged Linux. You can make programs using libc, boost, Qt, python, and even Java (using IcedTea).

Data: SMS, mails, contacts, files ?
Qt Mobility has a bunch of classes to access mail, texts and contacts.

Examples: Sample Phonebook, Contacts API Usage

The reason I'm pushing Qt so much is that it is really quite easy to start with, and there are even python bindings for it. It is cross platform so if designed correctly, you can have one code base for both ends of your data connection.

Thanks
Hope this helps.
