Builder

Builder

Builder()

Default constructor for the Builder.

build

fun build(): ResponderConfig

Build ResponderConfig given the current configurations made on the builder.

set80211azNtbSupported

fun set80211azNtbSupported(supports80211azNtb: Boolean): ResponderConfig.Builder

Sets an indication the access point can to respond to the IEEE 802.11az non-trigger based ranging protocol, but, if false, indicates only IEEE 802.11mc or one-sided Wi-Fi RTT is possible.

set80211mcSupported

fun set80211mcSupported(supports80211mc: Boolean): ResponderConfig.Builder

Sets an indication the access point can to respond to the two-sided Wi-Fi RTT protocol, but, if false, indicates only one-sided Wi-Fi RTT is possible.

setCenterFreq0Mhz

fun setCenterFreq0Mhz(centerFreq0: Int): ResponderConfig.Builder

Sets the center frequency in MHz of the first segment of the channel.

Note: The frequency is used as a hint, and the underlying WiFi subsystem may use it, or select an alternate if its own connectivity scans have determined the frequency of the access point has changed.

setCenterFreq1Mhz

fun setCenterFreq1Mhz(centerFreq1: Int): ResponderConfig.Builder

Sets the center frequency in MHz of the second segment of the channel, if used.

Note: The frequency is used as a hint, and the underlying WiFi subsystem may use it, or select an alternate if its own connectivity scans have determined the frequency of the access point has changed.

setChannelWidth

fun setChannelWidth(channelWidth: Int): ResponderConfig.Builder

Sets the channel bandwidth in MHz.

setFrequencyMhz

fun setFrequencyMhz(frequency: Int): ResponderConfig.Builder

Sets the frequency of the channel in MHz.

Note: The frequency is used as a hint, and the underlying WiFi subsystem may use it, or select an alternate if its own connectivity scans have determined the frequency of the access point has changed.

setMacAddress

fun setMacAddress(macAddress: MacAddress?): ResponderConfig.Builder

Sets the Responder MAC Address.

A responder must be identified by either a MacAddress or a PeerHandle (for Aware peers, set via #setPeerHandle(android.net.wifi.aware.PeerHandle)), but not both.

Note: This method sets the MAC address. If a PeerHandle was previously set using #setPeerHandle(android.net.wifi.aware.PeerHandle), both identifiers might be temporarily present within the builder. The final validation ensuring that only one of these identifiers is exclusively set occurs during the build() operation. If build() is called when both a MAC address and a PeerHandle are configured or when neither is set, it will result in an IllegalArgumentException.

setPreamble

fun setPreamble(preamble: Int): ResponderConfig.Builder

Sets the preamble encoding for the protocol.

setResponderType

fun setResponderType(responderType: Int): ResponderConfig.Builder

Sets the responder type, can be RESPONDER_AP or RESPONDER_STA or #RESPONDER_AWARE

setSecureRangingConfig

fun setSecureRangingConfig(secureRangingConfig: SecureRangingConfig): ResponderConfig.Builder

Set secure ranging configuration. See SecureRangingConfig for more details.

Note: Secure ranging will get enabled only if the device and responder support. For device support see WifiRttManager.getRttCharacteristics(). Following capabilities needs to be enabled,

• WifiRttManager.CHARACTERISTICS_KEY_BOOLEAN_NTB_INITIATOR
• WifiRttManager.CHARACTERISTICS_KEY_BOOLEAN_SECURE_HE_LTF_SUPPORTED and/or
• WifiRttManager.CHARACTERISTICS_KEY_BOOLEAN_RANGING_FRAME_PROTECTION_SUPPORTED

• ScanResult.capabilities string contains PASN and optionally a base AKM
• ScanResult.isSecureHeLtfSupported()
• ScanResult.isRangingFrameProtectionRequired()
