DfuOptions

data class DfuOptions(val prnInterval: Int = 10, val retryCount: Int = 3, val retryDelay: Duration = 2.seconds, val commandTimeout: Duration = 10.seconds, val transport: DfuTransportConfig = DfuTransportConfig.Gatt)

Configuration for a firmware update.

Defaults are tuned for Nordic nRF5 SDK Secure DFU over GATT.

Constructors

DfuOptions

constructor(prnInterval: Int = 10, retryCount: Int = 3, retryDelay: Duration = 2.seconds, commandTimeout: Duration = 10.seconds, transport: DfuTransportConfig = DfuTransportConfig.Gatt)

Properties

commandTimeout

val commandTimeout: Duration

how long to wait for a response to a DFU command

prnInterval

val prnInterval: Int

how many data packets to send before waiting for a receipt confirmation (Packet Receipt Notification). 0 disables PRNs — faster but removes flow control. Default 10.

retryCount

val retryCount: Int

maximum attempts per DFU object before giving up

retryDelay

val retryDelay: Duration

pause between retry attempts

transport

val transport: DfuTransportConfig

BLE transport to use — GATT (default) or L2CAP for higher throughput
