Auto-reconnect wrapper for SerialPilot.

Usage

const { SerialPilot } = require('serialpilot')
const { SerialPilotReconnect } = require('@serialpilot/reconnect')

const port = new SerialPilot({ path: '/dev/ttyUSB0', baudRate: 9600, autoOpen: false })
const reconnect = new SerialPilotReconnect({
  port,
  reconnectInterval: 1000,
  maxReconnectAttempts: 10,
  backoffFactor: 1.5,
})

reconnect.on('reconnecting', (attempt) => console.log(`Reconnect attempt ${attempt}`))
reconnect.on('reconnected', (attempt) => console.log(`Reconnected after ${attempt} attempts`))
reconnect.on('reconnect-failed', () => console.log('All reconnect attempts failed'))

reconnect.start()
port.open()

API

new SerialPilotReconnect(options)

• port — SerialPilotStream instance to manage
• autoReconnect — Enable auto-reconnect (default: true)
• reconnectInterval — ms between attempts (default: 1000)
• maxReconnectAttempts — Maximum attempts (default: Infinity)
• backoffFactor — Exponential backoff multiplier (default: 1)
• maxReconnectInterval — Cap for backoff in ms (default: 30000)
• deviceFilter — DeviceFilter to use when searching for device on reconnect
• onDisconnect — Callback on disconnect
• onReconnect — Callback on successful reconnect
• onReconnectFailed — Callback when all attempts exhausted

Events

• reconnecting — Emitted on each reconnect attempt
• reconnected — Emitted on successful reconnect
• reconnect-failed — Emitted when all attempts exhausted
• disconnect — Emitted when device disconnects

Methods

• start() — Begin monitoring for disconnects
• stop() — Stop monitoring and cancel pending reconnection
• forceReconnect() — Immediately attempt reconnection
