## Functions

### nm_access_point_get_flags ()

    NM80211ApFlags
    nm_access_point_get_flags (NMAccessPoint *ap);

Gets the flags of the access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the flags

### nm_access_point_get_wpa_flags ()

    NM80211ApSecurityFlags
    nm_access_point_get_wpa_flags (NMAccessPoint *ap);

Gets the WPA (version 1) flags of the access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the WPA flags

### nm_access_point_get_rsn_flags ()

    NM80211ApSecurityFlags
    nm_access_point_get_rsn_flags (NMAccessPoint *ap);

Gets the RSN (Robust Secure Network, ie WPA version 2) flags of the access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the RSN flags

### nm_access_point_get_ssid ()

    GBytes *
    nm_access_point_get_ssid (NMAccessPoint *ap);

Gets the SSID of the access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the GBytes containing the SSID, or `NULL` if the SSID is unknown.

[transfer none]

### nm_access_point_get_bssid ()

    const char *
    nm_access_point_get_bssid (NMAccessPoint *ap);

Gets the Basic Service Set ID (BSSID) of the Wi-Fi access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the BSSID of the access point. This is an internal string and must not be modified or freed.

### nm_access_point_get_frequency ()

    guint32
    nm_access_point_get_frequency (NMAccessPoint *ap);

Gets the frequency of the access point in MHz.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the frequency in MHz

### nm_access_point_get_mode ()

    NM80211Mode
    nm_access_point_get_mode (NMAccessPoint *ap);

Gets the mode of the access point.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the mode

### nm_access_point_get_max_bitrate ()

    guint32
    nm_access_point_get_max_bitrate (NMAccessPoint *ap);

Gets the maximum bit rate of the access point in kbit/s.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the maximum bit rate (kbit/s)

### nm_access_point_get_strength ()

    guint8
    nm_access_point_get_strength (NMAccessPoint *ap);

Gets the current signal strength of the access point as a percentage.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the signal strength (0 to 100)

### nm_access_point_get_last_seen ()

    int
    nm_access_point_get_last_seen (NMAccessPoint *ap);

Returns the timestamp (in CLOCK_BOOTTIME seconds) for the last time the access point was found in scan results. A value of -1 means the access point has not been found in a scan.

#### Parameters

ap | a NMAccessPoint |

#### Returns

the last seen time in seconds

Since: 1.2

### nm_access_point_filter_connections ()

    GPtrArray *
    nm_access_point_filter_connections (NMAccessPoint *ap,
                                        const GPtrArray *connections);

Filters a given array of connections for a given NMAccessPoint object and returns connections which may be activated with the access point. Any returned connections will match the `ap` 's SSID and (if given) BSSID and other attributes like security settings, channel, etc.

To obtain the list of connections that are compatible with this access point, use `nm_client_get_connections()` and then filter the returned list for a given NMDevice using `nm_device_filter_connections()` and finally filter that list with this function.

#### Parameters

ap | an NMAccessPoint to filter connections for |
connections | an array of NMConnections to filter. | [element-type NMConnection]

#### Returns

an array of NMConnections that could be activated with the given `ap` . The array should be freed with `g_ptr_array_unref()` when it is no longer required.

[transfer full][element-type NMConnection]

### nm_access_point_connection_valid ()

    gboolean
    nm_access_point_connection_valid (NMAccessPoint *ap,
                                      NMConnection *connection);

Validates a given connection against a given Wi-Fi access point to ensure that the connection may be activated with that AP. The connection must match the `ap` 's SSID, (if given) BSSID, and other attributes like security settings, channel, band, etc.

#### Parameters

ap | an NMAccessPoint to validate `connection` against |
connection | an NMConnection to validate against `ap` |

#### Returns

`TRUE` if the connection may be activated with this Wi-Fi AP, `FALSE` if it cannot be.
