nordic_dfu_web

This library allows you to do a Device Firmware Update (DFU) of your nrf51 or nrf52 chip from Nordic Semiconductor from Flutter Web

Getting started

add this package to pubspec.yaml file

nordic_dfu_web: 0.0.7

add this script tag in web/index.html file inside of head tag (check example folder)

<script src="./assets/packages/nordic_dfu_web/assets/ble.js" defer></script>

Features

To Start Dfu, Pick a file by using any File Picker Plugin and convert File to buffer, pass that buffer to this method and start DFU

Note: startDfu will open dialog to choose for a Device if , that device is already in Dfu mode , then it will start transferring firmware else ,device will be booted to Dfu and and it will throw an error, Also try to increase dfuDelay if getting any issue while transferring, to add filters, pass a list of requestBuilderFilter object, if passed an empty list , all devices will be shown in request builder

    await NordicDfuWeb.startDfu(
      uint8list: bytes,
      requestBuilderFilters: [],
      dfuDelay: 25,
      onProgress: (progress) {
        print(progress);
      },
