ResponderConfig


public final class ResponderConfig
extends Object implements Parcelable

java.lang.Object
   ↳ android.net.wifi.rtt.ResponderConfig


Defines the configuration of an IEEE 802.11mc Responder. The Responder may be an Access Point (AP), a Wi-Fi Aware device, or a manually configured Responder.

A Responder configuration may be constructed from a ScanResult or manually (with the data obtained out-of-band from a peer).

RESPONDER_AP

Added in API level 34
public static final int RESPONDER_AP

Responder is an access point(AP).

Constant Value: 0 (0x00000000)

RESPONDER_STA

Public methods

describeContents

Added in API level 33
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.
Value is either 0 or

equals

Added in API level 33
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

fromScanResult

Added in API level 33
public static ResponderConfig fromScanResult (ScanResult scanResult)

Creates a Responder configuration from a ScanResult corresponding to an Access Point (AP), which can be obtained from WifiManager.getScanResults().

Parameters
scanResult ScanResult: This value cannot be null.

Returns
ResponderConfig This value cannot be null.

getCenterFreq0Mhz

Added in API level 33
public int getCenterFreq0Mhz ()

If the Access Point (AP) bandwidth is 20 MHz, 0 MHz is returned. If the AP use 40, 80 or 160 MHz, this is the center frequency (in MHz). if the AP uses 80 + 80 MHz, this is the center frequency of the first segment (in MHz).

Returns
int the center frequency in MHz of the first channel segment.
Value is 0 or greater

getCenterFreq1Mhz

Added in API level 33
public int getCenterFreq1Mhz ()

If the Access Point (AP) bandwidth is 80 + 80 MHz, this param is not used and returns 0. If the AP uses 80 + 80 MHz, this is the center frequency of the second segment in MHz.

Returns
int the center frequency in MHz of the second channel segment (if used).
Value is 0 or greater

getFrequencyMhz

Added in API level 33
public int getFrequencyMhz ()

Returns
int the frequency in MHz of the Wi-Fi channel.
Value is 0 or greater

getMacAddress

Added in API level 33
public MacAddress getMacAddress ()

Returns
MacAddress the MAC address of the responder.
This value may be null.

getPeerHandle

Added in API level 33
public PeerHandle getPeerHandle ()

Returns the Wi-Fi Aware peer identifier of the responder.

This value is non-null if the responder is a Wi-Fi Aware peer and was configured using a PeerHandle (via ResponderConfig.Builder.setPeerHandle(PeerHandle)). The PeerHandle is an opaque identifier for a specific Aware peer discovered during Wi-Fi Aware operations, such as service discovery.

If the responder is not an Aware peer, or if it was configured using its MAC address (via ResponderConfig.Builder.setMacAddress(MacAddress)), this method will return null.

Only one of getPeerHandle() or getMacAddress() will return a non-null value for a valid ResponderConfig.

Returns
PeerHandle The PeerHandle of the Wi-Fi Aware responder, or null if the responder is not an Aware peer or is identified by its MAC address.

getPreamble

Added in API level 33
public int getPreamble ()

Get the preamble type of the channel.

Returns
int the preamble used for this channel.
Value is one of the following:

getResponderType

Added in API level 34
public int getResponderType ()

Get responder type.

Returns
int The type of this responder.
Value is one of the following:

getSecureRangingConfig

Added in API level 36
public SecureRangingConfig getSecureRangingConfig ()

Get secure ranging configuration.

Returns
SecureRangingConfig Secure ranging configuration. Returns null for non-secure ranging configuration.

getUsdPeerId

Added in API level 33
public int getUsdPeerId ()

Returns the USD peer identifier of the responder.

This value is non-negative if the responder is a USD peer and was configured using a peer ID (via ResponderConfig.Builder.setUsdPeerId(int)). The peer ID is an opaque identifier for a specific USD peer discovered during USD discovery operations.

Returns
int The peer ID of the USD responder, or -1 if not set.

hashCode

Added in API level 33
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

is80211azNtbSupported

Added in API level 35
public boolean is80211azNtbSupported ()

Returns
boolean true if the Responder supports the 802.11az non-trigger based ranging protocol, false otherwise.

is80211mcSupported

Added in API level 33
public boolean is80211mcSupported ()

Returns
boolean true if the Responder supports the 802.11mc protocol, false otherwise.

toString

Added in API level 33
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 33
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: This value cannot be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
Value is either 0 or a combination of the following:
