Fork from flutter_nordic_dfu and updated with latest dependencies, now with macOS support from version 6.0.0.

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

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

For more info about the DFU process, see: Resources

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

2. Run example project

3. Scan device

4. Start dfu

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

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');
      },
    );

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

Available from version 7.0.0

• DFU operations can run simultaneously on multiple devices.
• Callbacks are triggered correctly and independently for each device.

• Updated abortDfu method to include an optional address parameter:
  • If an address is provided: The DFU process for the specified device will be aborted. (iOS only)
  • If no address is provided: All active DFU processes will be aborted.
• Added error handling for abortDfu:
  • FlutterError("INVALID_ADDRESS") is thrown if the provided address does not match any active DFU process.
  • FlutterError("NO_ACTIVE_DFU") is thrown if no address is provided and there are no active DFU processes.

• ✅ Devices update in parallel.
• ✅ Callbacks set in startDfu are called independently for each device.
• ✅ All active DFU processes can be aborted using the abortDfu method without an address.
• ✅ DFU processes can be individually aborted using the abortDfu method with an address.

• ✅ Devices update in parallel (set limit of 8).
• ✅ Callbacks set in startDfu are called independently for each device.
• ✅ All active DFU processes can be aborted using the abortDfu method without an address.
• ❌ DFU processes cannot be individually aborted using the abortDfu method with an address due to current limitations in the underlying Android-DFU-Library.
