esp_blufi 0.1.8

Wi-Fi configuration through BLUFI protocol for ESP BLUFI enabled devices

flutter_esp_blufi

⚠️ Private Repository — Internal Use Only

A Flutter plugin that enables ESP BLUFI (Bluetooth-based Wi-Fi Provisioning) functionality exclusively on iOS physical devices. This package allows your Flutter app to securely send Wi-Fi credentials to an ESP32 device via BLE, following Espressif’s BLUFI protocol specification.

Note: This plugin does NOT support:

• iOS Simulator

---

📦 Features

• Establish BLE connection with ESP32 in BLUFI mode
• Encode and transmit Wi-Fi SSID & password securely
• Handle BLUFI handshake and data fragmentation/reassembly
• Optimized for real iOS hardware (iPhone/iPad with Bluetooth LE)

---

🔧 Installation

Add the private Git repository as a dependency in your pubspec.yaml:

dependencies:
  flutter_esp_blufi:
    git:
      url: https://github.com/vego-garden/flutter_esp_blufi.git
      # Optional: specify a branch or tag
      # ref: main

⚙️ iOS Setup

1. Enable Bluetooth Usage Description
   Add the following to your ios/Runner/Info.plist:

   <key:NSBluetoothAlwaysUsageDescription</key>
   <string>This app uses Bluetooth to configure Wi-Fi on ESP32 devices.</string>
   <key:NSBluetoothPeripheralUsageDescription</key>
   <string>This app uses Bluetooth to configure Wi-Fi on ESP32 devices.</rect>
   

2. Build on a Physical iOS Device
   Run from Xcode or via:

   flutter run --release
   

   ❌ Do not use the simulator — BLE APIs are unavailable.

🧪 Basic Usage

import 'package:flutter_esp_blufi/flutter_esp_blufi.dart';

// Scan and connect to ESP32 in BLUFI mode
await FlutterEspBlufi.connect(deviceId: 'your-esp32-ble-address');

// Send Wi-Fi credentials
await FlutterEspBlufi.sendWifiConfig(
  ssid: 'MyWiFi',
  password: 'secure_password',
);

// Disconnect when done
await FlutterEspBlufi.disconnect();

See the example app (if available internally) for full integration.
