+ | ==Introduction== | ||
+ | The maemo connectivity subsystem is implemented by using known Linux conventions. It resides in the user mode area of Linux, and relies on the Linux kernel through standard C libraries. Wireless LAN or WiMAX is the main channel to the Internet, but dial-up connections through cellular networks are also supported. The only medium to the phone is Bluetooth. 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. | ||

===Internet Access Points (IAP)=== | ===Internet Access Points (IAP)=== | ||
+ | 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, CSD, 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. | ||

This section describes the system decomposition of the Connectivity subsystem. Maemo applications can open Internet connections by using the LibConIC API. The Internet Access subsystem take care of the connection to the phone, if necessary, by using the services of the Phone Access subsystem. If an application needs to gain access to the phone's files, the File selector consults the Phone Access subsystem. | This section describes the system decomposition of the Connectivity subsystem.

+ | ===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.

When the device is not connected, it scans for saved IAPs and tries to connect automatically, taking into account the value defined by the search interval configuration parameter. The search interval can be 5, 10, 30 or 60 minutes; all other values are automatically mapped to "Never". This setup switches off the automatic connection feature.

You can switch off the automatic connection creation feature by using offline mode. While in this mode, the configuration parameter for allowing WLAN in offline mode is checked. Depending on the state of this configuration parameter, WLAN IAPs are either enabled or disabled in the offline mode. Also other radios like Bluetooth are normally disabled in the offline mode. | You can switch off the automatic connection creation feature by using offline mode.

- | === | + | ==== Bluetooth Dial-up Networking ==== |
+ | The ICd uses PPP to establish IP connectivity over Bluetooth DUN interfaces. If there already is a different IAP active using Bluetooth DUN, the old IAP is first deactivated. The IAP is activated according the following action sequence: | ||
+ | * The character device used by the Bluetooth DUN device is acquired from btcond. If the device is not available due to gateway not being present, exhaustion of simultaneous Bluetooth connections, or similar, the ICd shows an error message to the user and aborts with a D-BUS error message. | ||
+ | * The ICd starts PPP using the exec family of system calls. It directs PPP to use the acquired Bluetooth DUN device with the dial-up configuration parameters specified for the configured DUN IAP type. If PPP cannot get the connection established, the ICd shows an error message to the user and aborts with a D-BUS error message. When the PPP connection is established, PPP-specific scripts are run. The scripts configuration entries related to dynamic IP connectivity and send a state-change D-BUS message to all interested applications to indicate that the IAP has been established. | ||
+ | |||
+ | If the previously active IAP was not using Bluetooth DUN, it is closed down after establishing the PPP connection. | ||
+ | |||
+ | A Bluetooth DUN is closed down by sending the PPP daemon a SIGINT or SIGTERM signal. This terminates the PPP daemon and removes all routing entries associated with the PPP dial-up interface. The PPP shutdown scripts removes the dynamic IP connection related configuration entries and sends a state change D-BUS message announcing the deactivation of the IAP. | ||
+ | |||
+ | ==== WLAN ==== | ||
For connecting to a WLAN, the ICd needs to associate with the network as well as enable EAP authentication and the DHCP client as needed. Independently of whether an active IAP using WLAN exists, the requested WLAN network is first scanned to ensure that it is available. If the requested network is found and the current IAP is using WLAN, the current IAP is deactivated. WLAN is activated according to the following procedure: | For connecting to a WLAN, the ICd needs to associate with the network as well as enable EAP authentication and the DHCP client as needed.

==== Receiving Statistics of Connection ==== | ==== Receiving Statistics of Connection ==== | ||
+ | To receive statistics of the current Internet connection, use the ''con_ic_connection_statistics()'' function and the corresponding event handler. You can retrieve statistics for a specified IAP or just for the current default connection. Note that currently the Internet Connectivity daemon provides only one Internet connection at a time, so the best option is to leave IAP ID NULL. | ||

==== 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: | |

- | |||
- | |||
- | |||
- | + | ===Using Connection === | |
- | + | The libgwobex library provides general file handling functionality, including reading directory structure, browsing in different folders and getting files. | |
- | + | To read entries from an opened directory, use the following function: gw-obex.h | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | <tt>gboolean <span>'''<span><font color="#000000">gw_obex_read_dir</font></span>'''</span> <span><font color="#990000">(</font></span>GwObex <span><font color="#990000"><nowiki>*</nowiki></font></span> ctx<span><font color="#990000">,</font></span> | |

- | + | gw_obex_read_dir reads an entry from the selected folder and returns the result in the buf argument given to the function. | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | <tt>gboolean ret<span><font color="#990000"><nowiki>;</nowiki></font></span> | |

- | + | This reads an entry from the directory dir (char *) and returns it in buf (char **). | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | To change the current directory, use the following function: gw-obex.h | |
- | + | ||
- | + | <tt>gboolean <span>'''<span><font color="#000000">gw_obex_chdir</font></span>'''</span> <span><font color="#990000">(</font></span>GwObex <span><font color="#990000"><nowiki>*</nowiki></font></span> ctx<span><font color="#990000">,</font></span> <span>'''<span><font color="#0000FF">const</font></span>'''</span> gchar <span><font color="#990000"><nowiki>*</nowiki></font></span> dir<span><font color="#990000">,</font></span> gint <span><font color="#990000"><nowiki>*</nowiki></font></span> error <span><font color="#990000">);</font></span></tt> | |
- | + | ||
- | + | which changes the directory of the FTP connection. Below is a code example using this function. | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||

- | + | Using the libwobex wrapper directly allows you to perform many more functions. For more information, see the [hhttp://maemo.org/api_refs/5.0/beta/osso-gwobex/ API document]. | |

- | |||
- | + | ===Libopenobex === | |
- | + | The LibOpenOBEX library implements a generic OBEX Session Protocol, but not the OBEX Application Framework. OBEX is a protocol designed to allow data interchanging between different kinds of connections (e.g. Bluetooth, IrDA). For more information on the OBEX protocol, see [http://www.irda.org/ http://www.irda.org]<nowiki>; select the Developer->Specifications category. OBEX resembles the HTTP protocol, expect for a few differences: </nowiki> | |
- | + | ||
- | + | ||
- | + | * Transports: While HTTP is normally layered above a TCP/IP connection, OBEX is usually transported over IrLAP/IrLMP/Tiny TP (on IrDA) or over Baseband/Link Manager/L2CAP/RFCOMM (on Bluetooth). | |
- | + | * Binary transmissions: OBEX communicates using binary transmissions, as HTTP is transmitted in a human-readable XML-based format. | |
+ | * Session support: HTTP is stateless, while OBEX maintains the connection. | ||
- | + | For more information on OBEX, see the summary available at <br />http://en.wikipedia.org/wiki/OBEX. | |
- | + | ||
- | + | For libopenobex code samples, see <br />http://openobex.triq.net/downloads<nowiki>; the samples are in the example apps package. </nowiki> | |

- | + | ===Using BlueZ D-Bus API === | |
- | + | The BlueZ system exports a D-Bus API that can be employed instead of OSSO Bluetooth tools. See the following documents: | |
- | + | ||
- | + | ||
- | + | ||
- | + | * [http://bluez.cvs.sourceforge.net/*checkout*/bluez/utils/hcid/dbus-api.txt BlueZ D-Bus API documentation] | |

- | + | ==Connectivity UI == | |
- | + | ||
- | + | ===UI Components === | |
+ | Connectivity UI contains various dialogs and other components used to control the connectivity. The different UI parts are: | ||
- | + | * Connection manager | |
+ | * Connectivity dialogs | ||
+ | * Status bar applets | ||
+ | * Control panel applet | ||
+ | * Bluetooth UIs | ||
- | + | The connectivity dialogs are invoked by D-Bus method calls, so for example the ICd is using these D-Bus method calls for showing dialogs when they are needed. The next section specifies the D-Bus API of maemo connectivity UI. | |
- | |||
- | === | + | ===D-Bus Connectivity UI Interface === |
+ | If the user must provide information about the IAP that the system is about to connect to, you can use the following method: | ||
- | + | <div class="graybox"> | |

- | + | ==Location == | |
- | + | Location framework provides a library called liblocation which is used for developing location aware applications in Fremantle. Liblocation supports internal GPS, network based methods and external bluetooth GPS. | |

- | |||
- | |||
- | + | ===Using liblocation=== | |
- | / | + | To start implementing applications using liblocation API, you have to include the following headers. |
- | + | #include <location/location-gps-device.h> | |
+ | #include <location/location-gpsd-control.h> | ||
- | + | Liblocation has two public GObjects. LocationGPSDControl is used for starting and stopping of location services, setting location method and interval, and listening for errors. LocationGPSDevice has information about device status and contains the actual fix when one exists. The two GObjects are initiated as follows. | |
- | + | LocationGPSDControl *control = location_gpsd_control_get_default(); | |
- | + | LocationGPSDevice *device = g_object_new(LOCATION_TYPE_GPS_DEVICE, NULL); | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | * | + | |
- | |||
- | + | ===Location methods=== | |
- | + | Liblocation supports the following location methods which are defined in location-gpsd-control.h. | |
- | + | *'''LOCATION_METHOD_USER_SELECTED:''' Liblocation will choose the best possible location method based on location settings in control panel. If both gps and network positioning are enabled, then this will equal to ACWP+AGNSS. Choose this method if you don't have any special needs. | |
- | + | *'''LOCATION_METHOD_CWP - Complementary Wireless Positioning:''' The least accurate method with latitude and longitude of the fix pointing to the center of current country and horizontal accuracy being roughly radius of the country. SIM card is needed for CWP method. | |
+ | *'''LOCATION_METHOD_ACWP - Assisted Complementary Wireless Positioning:''' A method where device is located based on cellular base station, device is registered to. SIM card and a network connection is needed for ACWP method. If no network connection is available, this equals to CWP. Application might receive CWP fixes before base station information from external location server is fetched. | ||
+ | *'''LOCATION_METHOD_GNSS - Global Navigation Satellite System:''' A method for using GPS receiver. Typically time for the first fix is significantly longer than with AGNSS. Neither SIM card nor network connection is needed for GNSS method, and GNSS can even be used in offline mode. | ||
+ | *'''LOCATION_METHOD_AGNSS - Assisted Global Navigation Satellite System''' A method for using GPS receiver with assistance data from external location server. A SIM card and a network connection is needed for AGNSS method. If no network connection or SIM card is available, this equals to GNSS. | ||
- | + | Location resources are shared between applications, and applications can request different location methods. Fixes for all requested methods are sent for all applications listening to liblocation "changed" signal, therefore application should judge whether fix it is receiving, is one that it needs. See LocationGPSDeviceFix chapter for discussion. | |
- | + | ||
- | + | If device is set for bluetooth GPS from control panel, it can used for locationing via USER_SELECTED, AGNSS and GNSS methods. In this case AGNSS and GNSS do not differ, because assistance server cannot be utilized. | |
- | + | ||
- | + | ||
- | + | Device caches cell information for ACWP and satellite information for AGNSS. Hence if a non-assisted location method is used immediately after it's assisted counterpart, it will probably work as the assisted one. | |
- | + | Location method is set as LocationGPSDControl's "preferred-method" property. Several methods can be given by bitwise or'ing the method identifiers: | |
- | + | ||
- | + | ||
- | + | g_object_set(G_OBJECT(control), "preferred-method", LOCATION_METHOD_ACWP | LOCATION_METHOD_AGNSS, NULL); | |
- | + | ||
- | + | Here is table that summarizes differences between the methods. Accuracy refers to horizontal accuracy of the fix. | |

- | |||
- | |||
- | |||
- | |||
- | |||
- | |||
- | + | ===Location intervals=== | |
- | + | Liblocation supports a default interval and intervals of 1, 2, 5, 10, 20, 30, 60 and 120 seconds between fixes. These are defined in location-gpsd-control.h. Default interval means that several fixes are only sent when device's position changes, therefore it is a good choice for power consumption aware applications, and should be used if application doesn't have any special needs. | |
- | + | Due to the fact that location resources are shared between applications, setting interval to e.g. 5 seconds doesn't necessarily guarantee that you are getting fixes at 5 second interval, but the maximum time between fixes is 5 seconds. | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | Location interval is set as LocationGPSDControl's "preferred-interval" property: | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | + | g_object_set(G_OBJECT(control), "preferred-interval", LOCATION_INTERVAL_60S, NULL); | |
- | + | ||
- | + | ||
- | + | ||
- | + | ||
- | |||
- | |||
- | + | ===LocationGPSDevice and LocationGPSDeviceFix=== | |
- | + | LocationGPSDevice object has the following public fields: | |
- | + | *gboolean online: Whether there is a connection to the hardware | |
+ | *LocationGPSDeviceStatus status: Status of the device | ||
+ | *LocationGPSDeviceFix *fix: The actual fix (latitude, longitude, etc) | ||
+ | *int satellites_in_view: Number of satellites in view | ||
+ | *int satellites_in_use: Number of satellites in use | ||
+ | *GPtrArray *satellites: Array of satellites | ||
+ | *LocationCellInfo *cell_info: Information about cell the device is connected to | ||

- | + | The most useful field is naturally "fix" which contains position and movement of the device and accuracies for them. LocationGPSDeviceFix fields are listed below. In parenthesis there is a identifier which can be bitwisely anded with "fields" field, to see whether corresponding field is set. | |

- | + | *LocationGPSDeviceMode mode: The mode of the fix | |
- | + | *guint32 fields: A bitfield representing what fields contain valid data | |
- | + | *double time: The timestamp of the update (LOCATION_GPS_DEVICE_TIME_SET) | |
- | + | *double ept: Time accuracy | |
+ | *double latitude: Fix latitude (LOCATION_GPS_DEVICE_LATLONG_SET) | ||
+ | *double longitude: Fix longitude (LOCATION_GPS_DEVICE_LATLONG_SET) | ||

- | + | An application receiving a fix cannot know if the fix is a result from location method it requested. Therefore application should study whether fix is accurate enough to satisfy application's needs. This can be done by inspecting "eph" field, which is fix's horizontal accuracy in centimeters. Typical values for horizontal accuracies can be seen in the location methods table. If accuracy is not known, it has a value of NaN. | |

- | + | ===Liblocation signals and callbacks=== | |
- | + | The most useful signal in liblocation is LocationGPSDevice's "changed" signal, which is emitted everytime a new fix is received. LocationGPSDControl has an "error" signal which is emitted in case of an error. You can connect to these signals in the usual way: | |
- | + | g_signal_connect(control, "error", G_CALLBACK(on_error), user_data); | |
- | + | g_signal_connect(device, "changed", G_CALLBACK(on_changed), user_data); | |
- | + | ||
- | + | Below is an example for these signals' callbacks. | |
- | + | static void on_error(LocationGPSDControl *control, gpointer user_data) | |
- | + | { | |
- | + | g_debug("Location error"); | |
- | + | } | |
- | + | ||
- | + | static void on_changed(LocationGPSDevice *device, gpointer user_data) | |
- | + | { | |
- | + | if (!device) | |
- | + | return; | |
- | + | ||
- | + | if (device->fix) { | |
- | + | if (device->fix->fields & LOCATION_GPS_DEVICE_LATLONG_SET) | |
- | + | g_debug("lat = %f, long = %f", device->fix->latitude, device->fix->longitude); | |
- | + | ||
+ | if (device->fix->fields & LOCATION_GPS_DEVICE_ALTITUDE_SET) | ||
+ | g_debug("alt = %f", device->fix->altitude); | ||
+ | |||
+ | g_debug("horizontal accuracy: %f meters", device->fix->eph/100); | ||
+ | } | ||
+ | |||
+ | if (device && device->cell_info) { | ||
+ | if (device->cell_info->flags & LOCATION_CELL_INFO_GSM_CELL_INFO_SET) | ||
+ | g_debug("Mobile Country Code GSM: %d", device->cell_info->gsm_cell_info.mcc); | ||
+ | |||
+ | if (device->cell_info->flags & LOCATION_CELL_INFO_WCDMA_CELL_INFO_SET) | ||
+ | g_debug("Mobile Country Code WCDMA: %d", device->cell_info->wcdma_cell_info.mcc); | ||
+ | } | ||
+ | |||
+ | g_debug("Satellites in view: %d, in use: %d", | ||
+ | device->satellites_in_view, device->satellites_in_use); | ||
+ | } | ||
- | + | Liblocation sends a "changed" signal also after locationing is started or stopped, in which case a last known fix is sent if such exists. Application can differentiate these fixes from real ones by inspecting device->status field which equals LOCATION_GPS_DEVICE_STATUS_NO_FIX if the fix is not real. | |

- | |||
- | |||
- | |||
- | |||
- | |||
- | |||
- | + | ===Starting and stopping locationing=== | |
- | + | Finally after everything above has been done, locationing can be started. | |
+ | location_gpsd_control_start(control); | ||
- | + | If the chosen location method violates control panel location settings, then a dialog is shown to user. Dialogs ask user to enable necessary services. On user's refusal an error to application is sent. If no error is seen, fixes should be coming after a while. When locationing is no longer needed, it can be stopped. | |
- | + | location_gpsd_control_stop(control); | |
- | |||
- | |||
- | |||
- | + | ===Complete example=== | |
- | [ | + | Here is a complete standalone example using liblocation. It starts location services after program is started, then when first fix arrives, prints it, stops services, and shutdowns. |
- | + | #include <location/location-gps-device.h> | |
+ | #include <location/location-gpsd-control.h> | ||
+ | |||
+ | static void on_error(LocationGPSDControl *control, gpointer data) | ||
+ | { | ||
+ | g_debug("location error... quitting"); | ||

+ | } | ||
+ | |||
+ | static void on_changed(LocationGPSDevice *device, gpointer data) | ||
+ | { | ||
+ | if (!device) | ||
+ | return; | ||
+ | |||
+ | if (device->fix) { | ||
+ | if (device->fix->fields & LOCATION_GPS_DEVICE_LATLONG_SET) { | ||
+ | g_debug("lat = %f, long = %f", device->fix->latitude, device->fix->longitude); | ||
+ | location_gpsd_control_stop((LocationGPSDControl *) data); | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | |||
+ | static void on_stop(LocationGPSDControl *control, gpointer data) | ||
+ | { | ||
+ | g_debug("quitting"); | ||
+ | g_main_loop_quit((GMainLoop *) data); | ||
+ | } | ||
+ | |||
+ | static gboolean start_location(gpointer data) | ||
+ | { | ||
+ | location_gpsd_control_start((LocationGPSDControl *) data); | ||
+ | return FALSE; | ||
+ | } | ||
+ | |||
+ | int main(int argc, char *argv[]) | ||
+ | { | ||
+ | LocationGPSDControl *control; | ||
+ | LocationGPSDevice *device; | ||
+ | GMainLoop *loop; | ||
+ | |||
+ | g_type_init(); | ||
+ | |||
+ | loop = g_main_loop_new(NULL, FALSE); | ||
+ | |||
+ | control = location_gpsd_control_get_default(); | ||
+ | device = g_object_new(LOCATION_TYPE_GPS_DEVICE, NULL); | ||
+ | |||
+ | g_object_set(G_OBJECT(control), | ||
+ | "preferred-method", LOCATION_METHOD_USER_SELECTED, | ||
+ | "preferred-interval", LOCATION_INTERVAL_DEFAULT, | ||
+ | NULL); | ||
+ | |||
+ | g_signal_connect(control, "error", G_CALLBACK(on_error), loop); | ||
+ | g_signal_connect(device, "changed", G_CALLBACK(on_changed), control); | ||
+ | g_signal_connect(control, "gpsd-stopped", G_CALLBACK(on_stop), loop); | ||
+ | |||
+ | g_idle_add(start_location, control); | ||
+ | |||
+ | g_main_loop_run(loop); | ||
+ | |||
+ | g_object_unref(device); | ||
+ | g_object_unref(control); | ||
+ | |||
+ | return 0; | ||
+ | } | ||
+ | |||
+ | You can compile this example with following command: | ||
+ | gcc -Wall `pkg-config --cflags gl |
