Types

MergeResult

sealed class MergeResult

The result of the Flow.merge operation.

Properties

baseUuid

val Uuid.Companion.baseUuid: Uuid

Bluetooth UUIDs are 128-bit values used to uniquely identify services, characteristics, and descriptors. They are defined by the Bluetooth Special Interest Group (SIG).

is16BitUuid

val Uuid.is16BitUuid: Boolean

Check whether the given UUID is a 16-bit UUID.

is32BitUuid

val Uuid.is32BitUuid: Boolean

Check whether the given UUID is a 32-bit UUID.

isShortUuid

val Uuid.isShortUuid: Boolean

Check whether the given UUID is a 16-bit or 32-bit UUID.

shortUuid

val Uuid.shortUuid: Int?

Extract the 16-bit or 32-bit Service Identifier of the 128-bit UUID.

Functions

and

infix fun Uuid.and(other: Uuid): Uuid

Creates a new UUID by doing a binary AND operation on bits of both UUIDs.

chunk

fun Flow<ByteArray>.chunk(size: Int): Flow<ByteArray>

Collects the flow of data and emits a new flow of packet of at-most given size.

fun Flow<ByteArray>.chunk(size: Int, operation: suspend (data: ByteArray, size: Int) -> List<ByteArray>): Flow<ByteArray>

Collects the flow of data and emits a new flow of chunked data using the given operation.

chunked

fun ByteArray.chunked(size: Int): List<ByteArray>

Splits the data into chunks of given length. The last chunk may be shorter.

distinct

fun <ID : Any, T : Peer<ID>> Flow<T>.distinct(): Flow<T>

Returns a flow that emits only distinct peers.

fromBytes

fun Uuid.Companion.fromBytes(uuidBytes: ByteArray): Uuid

fun Uuid.Companion.fromBytes(uuidBytes: ByteArray, offset: Int, length: Int): Uuid

Converts 2, 4 or 16 byte array to a UUID using Little Endian byte order.

fromShortUuid

fun Uuid.Companion.fromShortUuid(shortUuid: Int): Uuid

Creates a 128-bit UUID from a 16-bit or 32-bit UUID using Bluetooth Base UUID.

merge

fun Flow<ByteArray>.merge(operation: suspend (accumulator: ByteArray, received: ByteArray) -> MergeResult): Flow<ByteArray>

Collects the flow of packets and emits a new flow of merged data using the given operation.

mergeIndexed

fun Flow<ByteArray>.mergeIndexed(operation: suspend (accumulator: ByteArray, received: ByteArray, index: Int) -> MergeResult): Flow<ByteArray>

Collects the flow of packets and emits a new flow of merged data using the given operation.

toShortByteArray

fun Uuid.toShortByteArray(): ByteArray

Returns the UUID as Byte Array, in Little Endian.

toShortString

fun Uuid.toShortString(): String

Returns a string representation of the UUID.
