class BluetoothHidDeviceAppQosSettings : Parcelable

kotlin.Any
↳	android.bluetooth.BluetoothHidDeviceAppQosSettings

Represents the Quality of Service (QoS) settings for a Bluetooth HID Device application.

The BluetoothHidDevice framework will update the L2CAP QoS settings for the app during registration.

Summary

Constants
static Int	MAX
static Int	SERVICE_BEST_EFFORT
static Int	SERVICE_GUARANTEED
static Int	SERVICE_NO_TRAFFIC

Inherited constants

From class Parcelable Int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. Int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public constructors
BluetoothHidDeviceAppQosSettings(serviceType: Int, tokenRate: Int, tokenBucketSize: Int, peakBandwidth: Int, latency: Int, delayVariation: Int) Create a BluetoothHidDeviceAppQosSettings object for the Bluetooth L2CAP channel.

Create a BluetoothHidDeviceAppQosSettings object for the Bluetooth L2CAP channel. The QoS Settings is optional. Please refer to Bluetooth HID Specification v1.1.1 Section 5.2 and Appendix D for parameters.

Parameters
serviceType	Int: L2CAP service type, default = SERVICE_BEST_EFFORT
tokenRate	Int: L2CAP token rate, default = 0
tokenBucketSize	Int: L2CAP token bucket size, default = 0
peakBandwidth	Int: L2CAP peak bandwidth, default = 0
latency	Int: L2CAP latency, default = MAX
delayVariation	Int: L2CAP delay variation, default = MAX
