nordic_dfu

5.0.0 Breaking changes!

From version 5.0.0, the callbacks are defined as function parameters in NordicDfu().startDfu(). Please see the example app for more information.

4.0.0 Breaking changes!

From version 4.0.0, the NordicDfu class uses a Singleton. If you are comming from an older version, you have to change the notation from NordicDfu.startDfu() to NordicDfu().startDfu().

Fork from flutter_nordic_dfu and updated with latest dependencies.

This library allows you to do a Device Firmware Update (DFU) of your nrf51 or nrf52 chip from Nordic Semiconductor. It works for Android and iOS.

This is the implementation of the reference "react-native-nordic-dfu"

For more info about the DFU process, see: Resources

Run example

1. Add your dfu zip file to example/assets/file.zip

2. Run example project

3. Scan device

4. Start dfu

Usage

You can pass an absolute file path or asset file to NordicDfu

Use absolute file path

await NordicDfu().startDfu(
            'EB:75:AD:E3:CA:CF', '/file/to/zip/path/file.zip'
         );
// With callback
await NordicDfu().startDfu(
      'EB:75:AD:E3:CA:CF',
      'assets/file.zip',
      fileInAsset: true,
      onProgressChanged: (
        deviceAddress,
        percent,
        speed,
        avgSpeed,
        currentPart,
        partsTotal,
      ) {
        print('deviceAddress: $deviceAddress, percent: $percent');
      },
    );

Use asset file path

/// just set [fileInAsset] true
await NordicDfu().startDfu(
            'EB:75:AD:E3:CA:CF', 'assets/file.zip',
            fileInAsset: true,
         );
