Hello all, I am looking for some help with using NetworkManager in a c++ application.
I am able to use network manager to scan the list of ap's and also go through the list of connections. I think if the network is already listed in the connection list I need to activate it instead of trying to add it. However what I am missing is how do I activate the wireless connection and how do I set the WPA2 key (or other key depending on the security used) I have not found any code examples on how to use ActivateConnection or AddAndActivateConnection2 methods. Below was an attempt I made at setting up the connection (borrowed heavily from https://github.com/lcp/NetworkManager/blob/master/examples/C/glib/add-connection-libnm-glib.c ) gboolean NetworkSettings::add_connection(NMRemoteSettings *settings, GMainLoop *loop, const char *con_name, std::string SSID, std::string sKey) { NMConnection *connection; NMSettingConnection *s_con; NMSettingWireless *s_wireless; NMSettingIP4Config *s_ip4; char *uuid; gboolean success; // Create a new connection object connection = nm_connection_new(); // Build up the 'connection' Setting s_con = (NMSettingConnection *)nm_setting_connection_new(); uuid = nm_utils_uuid_generate(); g_object_set(G_OBJECT(s_con), NM_SETTING_CONNECTION_UUID, uuid, NM_SETTING_CONNECTION_ID, con_name, NM_SETTING_CONNECTION_TYPE, "802-11-wireless", NULL); g_free(uuid); nm_connection_add_setting(connection, NM_SETTING(s_con)); // Build up the 'wireless' Setting s_wireless = (NMSettingWireless *)nm_setting_wireless_new(); g_object_set(G_OBJECT(s_wireless), NM_SETTING_WIRELESS_SSID, SSID.c_str(), NM_SETTING_WIRELESS_SEC, sKey.c_str(), NULL); nm_connection_add_setting(connection, NM_SETTING(s_wireless)); // Build up the 'ipv4' Setting s_ip4 = (NMSettingIP4Config *)nm_setting_ip4_config_new(); g_object_set(G_OBJECT(s_ip4), NM_SETTING_IP4_CONFIG_METHOD, NM_SETTING_IP4_CONFIG_METHOD_AUTO, NULL); nm_connection_add_setting(connection, NM_SETTING(s_ip4)); // Ask the settings service to add the new connection; we'll quit the // mainloop and exit when the callback is called. success = nm_remote_settings_add_connection(settings, connection, NetworkSettings::added_cb, loop); if(!success) g_print("Error adding connection\n"); g_object_unref(connection); return success; }
