build

fun build(): WifiP2pConfig

Build WifiP2pConfig given the current requests made on the builder.

enablePersistentMode

fun enablePersistentMode(persistent: Boolean): WifiP2pConfig.Builder

Specify that the group configuration be persisted (i.e. saved). By default the group configuration will not be saved.

Optional. false by default.

setDeviceAddress

fun setDeviceAddress(deviceAddress: MacAddress?): WifiP2pConfig.Builder

Specify the peer's MAC address. If not set, the device will try to find a peer whose SSID matches the network name as specified by setNetworkName(java.lang.String). Specifying null will reset the peer's MAC address to "02:00:00:00:00:00".

Optional. "02:00:00:00:00:00" by default.

If the network name is not set, the peer's MAC address is mandatory.

setGroupClientIpProvisioningMode

fun setGroupClientIpProvisioningMode(groupClientIpProvisioningMode: Int): WifiP2pConfig.Builder

Specify the IP provisioning mode when joining a group as a group client. The IP provisioning mode should be GROUP_CLIENT_IP_PROVISIONING_MODE_IPV4_DHCP or GROUP_CLIENT_IP_PROVISIONING_MODE_IPV6_LINK_LOCAL.

When joining a group as group client using android.net.wifi.p2p.WifiP2pManager#connect(android.net.wifi.p2p.WifiP2pManager.Channel,android.net.wifi.p2p.WifiP2pConfig,android.net.wifi.p2p.WifiP2pManager.ActionListener), specifying GROUP_CLIENT_IP_PROVISIONING_MODE_IPV4_DHCP directs the system to assign a IPv4 to the group client using DHCP. Specifying GROUP_CLIENT_IP_PROVISIONING_MODE_IPV6_LINK_LOCAL directs the system to assign a link-local IPv6 to the group client.

Optional. GROUP_CLIENT_IP_PROVISIONING_MODE_IPV4_DHCP by default.

If WifiP2pManager.isGroupOwnerIPv6LinkLocalAddressProvided() is true and GROUP_CLIENT_IP_PROVISIONING_MODE_IPV6_LINK_LOCAL is used then the system will discover the group owner's IPv6 link-local address and broadcast it using the WifiP2pManager.EXTRA_WIFI_P2P_INFO extra of the WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION broadcast. Otherwise, if WifiP2pManager.isGroupOwnerIPv6LinkLocalAddressProvided() is false then the group owner's IPv6 link-local address is not discovered and it is the responsibility of the caller to obtain it in some other way, e.g. via out-of-band communication.

setGroupOperatingBand

fun setGroupOperatingBand(band: Int): WifiP2pConfig.Builder

Specify the band to use for creating the group or joining the group. The band should be GROUP_OWNER_BAND_2GHZ, GROUP_OWNER_BAND_5GHZ or GROUP_OWNER_BAND_6GHZ or GROUP_OWNER_BAND_AUTO.

When creating a group as Group Owner using android.net.wifi.p2p.WifiP2pManager#createGroup(android.net.wifi.p2p.WifiP2pManager.Channel,android.net.wifi.p2p.WifiP2pConfig,android.net.wifi.p2p.WifiP2pManager.ActionListener), specifying GROUP_OWNER_BAND_AUTO allows the system to pick the operating frequency from all supported bands. Specifying GROUP_OWNER_BAND_2GHZ or GROUP_OWNER_BAND_5GHZ or GROUP_OWNER_BAND_6GHZ only allows the system to pick the operating frequency in the specified band. If the Group Owner cannot create a group in the specified band, the operation will fail.

When joining a group as Group Client using android.net.wifi.p2p.WifiP2pManager#connect(android.net.wifi.p2p.WifiP2pManager.Channel,android.net.wifi.p2p.WifiP2pConfig,android.net.wifi.p2p.WifiP2pManager.ActionListener), specifying GROUP_OWNER_BAND_AUTO allows the system to scan all supported frequencies to find the desired group. Specifying GROUP_OWNER_BAND_2GHZ or GROUP_OWNER_BAND_5GHZ or GROUP_OWNER_BAND_6GHZ only allows the system to scan the specified band.

setGroupOperatingBand(int) and setGroupOperatingFrequency(int) are mutually exclusive. Setting operating band and frequency both is invalid.

Optional. GROUP_OWNER_BAND_AUTO by default.

setGroupOperatingFrequency

fun setGroupOperatingFrequency(frequency: Int): WifiP2pConfig.Builder

Specify the frequency, in MHz, to use for creating the group or joining the group.

When creating a group as Group Owner using WifiP2pManager.createGroup(, specifying a frequency only allows the system to pick the specified frequency. If the Group Owner cannot create a group at the specified frequency, the operation will fail. When not specifying a frequency, it allows the system to pick operating frequency from all supported bands.

When joining a group as Group Client using WifiP2pManager.connect(, specifying a frequency only allows the system to scan the specified frequency. If the frequency is not supported or invalid, the operation will fail. When not specifying a frequency, it allows the system to scan all supported frequencies to find the desired group.

setGroupOperatingBand(int) and setGroupOperatingFrequency(int) are mutually exclusive. Setting operating band and frequency both is invalid.

Optional. 0 by default.

setNetworkName

fun setNetworkName(networkName: String): WifiP2pConfig.Builder

Specify the network name, a.k.a. group name, for creating or joining a group.

A network name shall begin with "DIRECT-xy". x and y are selected from the following character set: upper case letters, lower case letters and numbers. Any byte values allowed for an SSID according to IEEE802.11-2012 [1] may be included after the string "DIRECT-xy" (including none).

Must be called - an empty network name or an network name not conforming to the P2P Group ID naming rule is not valid.

setPassphrase

fun setPassphrase(passphrase: String): WifiP2pConfig.Builder

Specify the passphrase for creating or joining a group.

The passphrase must be an ASCII string whose length is, 1. Between 8 and 63 for PCC_MODE_CONNECTION_TYPE_LEGACY_ONLY and PCC_MODE_CONNECTION_TYPE_LEGACY_OR_R2. 2. Less than 128 for PCC_MODE_CONNECTION_TYPE_R2_ONLY.

Must be called - an empty passphrase is not valid.
