nrf_ble_dfu 1.0.0

Core Nordic BLE DFU protocol implementation in pure Dart. Helps enable firmware updates of BLE devices over Bluetooth Low Energy.

NRF BLE DFU (Core)

The core Nordic DFU over BLE library in pure Dart. This package helps enable firmware updates of BLE devices over Bluetooth Low Energy (BLE) in a platform-independent way.

It provides a decoupled implementation of the Nordic DFU protocol (CRC32 calculations, data packeting, command control states) without depending on the Flutter SDK.

If you are building a Flutter application with ready-to-use widgets and plugin bindings (like flutter_blue_plus and shared_preferences), please use the flutter_nrf_ble_dfu package instead.

Getting Started

To use this core library, you must provide your own platform adapters implementing the required interfaces:

• DfuBleAdapter, DfuBleDevice, DfuBleCharacteristic, DfuBleService
• DfuStorageAdapter
• DfuPathAdapter
• DfuDatabaseAdapter

Then initialize the engine:

import 'package:nrf_ble_dfu/nrf_ble_dfu.dart';

void main() {
  NrfBleDfu().initialize(
    bleAdapter: MyBleAdapter(),
    storageAdapter: MyStorageAdapter(),
    pathAdapter: MyPathAdapter(),
    databaseAdapter: MyDatabaseAdapter(),
  );
}
