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.

Parameters
supports80211azNtb	Boolean: the ability to support the IEEE 802.11az non-trigger based ranging protocol

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

set80211mcSupported

Added in API level 33

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.

Parameters
supports80211mc	Boolean: the ability to support the Wi-Fi RTT protocol

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setCenterFreq0Mhz

Added in API level 33

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.

Parameters
centerFreq0	Int: the center frequency in MHz of first channel segment Value is 0 or greater

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setCenterFreq1Mhz

Added in API level 33

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.

Parameters
centerFreq1	Int: the center frequency in MHz of second channel segment Value is 0 or greater

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setChannelWidth

Added in API level 33

fun setChannelWidth(channelWidth: Int): ResponderConfig.Builder

Sets the channel bandwidth in MHz.

Parameters
channelWidth	Int: the bandwidth of the channel in MHz Value is android.net.wifi.ScanResult#CHANNEL_WIDTH_20MHZ, android.net.wifi.ScanResult#CHANNEL_WIDTH_40MHZ, android.net.wifi.ScanResult#CHANNEL_WIDTH_80MHZ, android.net.wifi.ScanResult#CHANNEL_WIDTH_160MHZ, android.net.wifi.ScanResult#CHANNEL_WIDTH_80MHZ_PLUS_MHZ, or android.net.wifi.ScanResult#CHANNEL_WIDTH_320MHZ

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setFrequencyMhz

Added in API level 33

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.

Parameters
frequency	Int: the frequency of the channel in MHz Value is 0 or greater

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setMacAddress

Added in API level 33

fun setMacAddress(macAddress: MacAddress): ResponderConfig.Builder

Sets the Responder MAC Address.

Parameters
macAddress	MacAddress: the phyical address of the responder This value cannot be null.

Return
ResponderConfig.Builder	the builder to facilitate chaining builder.setXXX(..).setXXX(..). This value cannot be null.

setSecureRangingConfig

Added in API level Baklava

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,

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

Parameters
secureRangingConfig	SecureRangingConfig: Secure ranging configuration This value cannot be null.
