+ | ==Introduction== | ||
+ | The maemo connectivity subsystem is implemented by using known Linux conventions. It resides in the user space of Linux, and relies on the Linux kernel through standard C libraries. GPRS or WLAN is the main channel to the Internet. The Bluetooth software of maemo is based on BlueZ, which is known as the de-facto implementation of Bluetooth for Linux. D-Bus is used for internal application level message exchange. | ||
Even though the connectivity device drivers are closely related to this subsystem, they are considered to be outside of the scope of this manual. | Even though the connectivity device drivers are closely related to this subsystem, they are considered to be outside of the scope of this manual. | ||

The central concept for maemo Internet connections is the Internet Access Point (IAP), which represents a logical Internet (IP) connection that the user defines. An IAP has a unique name, usually in form of UUID). Among other things, it defines the radio bearer (e.g. WLAN, GPRS), and usually also the data transfer speed, username, password, proxy server, and the corresponding access point in the Internet or the telephone number of the service provider's modem. | The central concept for maemo Internet connections is the Internet Access Point (IAP), which represents a logical Internet (IP) connection that the user defines.

+ | ===Phone Access === | ||
Phone Access is the subsystem handling connections to a cellular phone. It offers a search utility for finding potential phones and inquiring the services they can offer. This is based on the standard Bluetooth service discovery mechanism. Phone Access also keeps a record of phones that have connected to the device in GConf, and provides a list of them for the user to choose from. Phone Access relies on the Linux Bluetooth implementation called BlueZ. BlueZ offers the Berkeley socket interface to the HCI and to the L2CAP protocol for the user space applications. | Phone Access is the subsystem handling connections to a cellular phone.

However, different mobile phones implement varying levels of file transfer services and OBEX. Some products limit access to the Inbox (Object Push), whereas more sophisticated ones make the Gallery and the memory card available. The recent products support the OBEX Capability request for retrieving more specific information about the file system on the phone. |
Maemo connects to a phone on an on-demand basis, such as when an application requires a connection. For example, when the Internet browser is about to open a URL, it requests Phone Access to establish a connection to the phone. This causes Phone Access to bind an RFCOMM device to the requested service on the phone. In a similar fashion, the File Selector can set up a file transfer connection to the phone using another RFCOMM device. After binding to a service, the application in question can open the local RFCOMM device. Normal file selector access is performed with GnomeVFS layer to get transparent access to phone in the same way as internal flash and MMC are accessed. | Maemo connects to a phone on an on-demand basis, such as when an application requires a connection.

==== Requesting for Connection ==== | ==== Requesting for Connection ==== | ||
+ | Libconic is an asynchronous connection API, which heavily relies on GObject signals. Basically this means that GMainloop must be iterated in order to successfully execute connection requests. After the application is set up, use a ''ConIcConnection'' object to request a connection: | ||

- | + | At this point, the application does not yet have an Internet connection. A successful return from ''con_ic_connection_connect()'' means only that the request was successfully dispatched to the Internet Connectivity daemon. When the daemon has a connection ready, the application receives an event (as an GObject signal) indicating that the device is connected. If the connection attempt fails, the application receives a disconnected event with an error describing the reason for the failure. | |

==== Getting Proxy Settings ==== | ==== Getting Proxy Settings ==== | ||
+ | Libconic allows you to set up Internet connection proxy settings for various protocols. The first step is to discover the current proxy mode by using the ''con_ic_connection_get_proxy_mode()'' function. Next, use the following functions to get the actual proxy settings: | ||
- | + | * If proxy mode is CON_IC_PROXY_MODE_NONE, do not use any proxies. | |
+ | * If proxy mode is CON_IC_PROXY_MODE_MANUAL, use the following functions to query proxy settings: | ||
+ | ** con_ic_connection_get_proxy_host() to get the proxy host | ||
+ | ** con_ic_connection_get_proxy_port() to get the proxy port | ||
+ | ** con_ic_connection_get_proxy_ignore_hosts() to get a list of hosts for which the proxy should not be used. | ||
+ | * If proxy mode is CON_IC_PROXY_MODE_AUTO, use <br /> con_ic_connection_get_proxy_autoconfig_url() to get a proxy auto configuration URL. | ||
+ | ** Use of auto configuration URL is explained in [http://en.wikipedia.org/wiki/Proxy_auto-config Wikipedia] | ||
- | + | In this example, the "connection-event" handler is modified to print HTTP proxy settings when establishing connection: | |
