FakeDfuTransport

class FakeDfuTransport(val mtu: Int = 20) : DfuTransport

In-memory DfuTransport for testing DFU flows without BLE hardware.

Queue responses with enqueueResponse before the code-under-test calls sendCommand. After the DFU completes, inspect getCommandLog and getDataLog to verify the commands and data packets that were sent.

Usage

val transport = FakeDfuTransport(mtu = 64)
// Queue the expected DFU responses...
transport.enqueueResponse(selectResponse)
transport.enqueueResponse(createResponse)
// ...then run the protocol under test

Parameters

mtu

simulated maximum write payload size

Constructors

Clear both command and data logs.

open override fun close()

Release transport resources synchronously.

emitNotification

suspend fun emitNotification(data: ByteArray)
