nordic_dfu's Introduction

nordic_dfu

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

Run example

Add your dfu zip file to example/assets/file.zip
Run example project
Scan device
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,
         );

I can't use it on IOS

This is my platform information:
flutter:3.0.5
XCODE 13.41
ios: IPhone 12 mini (15.5)

It seems to be connected in a loop all the time,like this:

this my code:

fileInAsset: false,

avgSpeed,
currentPart,
partsTotal,
) async {
debugPrint('deviceAddress: $deviceAddress, percent: $percent');

  sendvalue = percent;
  if (sendvalue == 100) {
    await Future.delayed(const Duration(seconds: 3));
    Navigator.pop(context, true);
  }
}, onDeviceConnected: ((str) {
  print("onDeviceConnected:" + str);

What should I do now?

Enhancement Request - DFU update using downloaded file

Hi, Thank you for maintaining this package and migrating it to null safety. I have successfully integrated it into my project using a zip file in my flutter project just like the example project and it works as expected.

In my app I'd like to be able to get the zip firmware file from an API download rather than a local file so the user will always have access to the newest firmware.

I can use an HTTP request to get the file contents but this package does not appear to have a method to update the firmware in this manner.

Would this be an enhancement that you can add or could you please point me in the right direction of some workaround?

Thank you!

Android manifest should not restrict maxSdkVersion

I have an issue when i try to upload my app to google console.
I get the 2 errors:

Duplicate declarations of element 'android.permission.ACCESS_FINE_LOCATION' in manifest with different maxSdkVersion.
Duplicate declarations of element 'android.permission.ACCESS_COARSE_LOCATION' in manifest with different maxSdkVersion.

it's true that the official docs state that fine location is no longer needed for BLE scanning but i found that i was not able to get BLE scan results unless i have location (fine) enabled.

I also found that other developers encounter this issue

My android manifest does not restrict max SDK version, but this library does with the following:

<!-- required for API 23 - 30 -->
    <uses-permission-sdk-23
        android:name="android.permission.ACCESS_COARSE_LOCATION"
        android:maxSdkVersion="30" />
    <uses-permission-sdk-23
        android:name="android.permission.ACCESS_FINE_LOCATION"
        android:maxSdkVersion="30" />

the change that is needed:

<uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission-sdk-23 android:name="android.permission.ACCESS_FINE_LOCATION" />

For now, my workaround is to edit this library AndroidManifest so i will be able to upload my app to google console.

DFU Fails with `201` on iOS

Hi,
After I startDFU i'm getting the following error on iOS while on Android it works fine:

PlatformException(201, FU FAILED: Device failed to connect, Address: B62B1F0B-8421 DC3A-50D1-B511CC27B4E6, Error type 201, null)

Here is the startDFU Code:

Future<void> doDfu(String deviceId) async {
    stateDFU = UpdateProcessStates.UpdateProcessStatesUpdating;
    try {
      var s = await NordicDfu().startDfu(
        deviceId,
        '${widget.path}',
        fileInAsset: false,
        iosSpecialParameter: IosSpecialParameter(
          forceScanningForNewAddressInLegacyDfu: true,
        ),
        onDeviceDisconnecting: (string) {
          debugPrint('deviceAddress: $string');
        },
        onProgressChanged: (

        ) {

          setState(() {

      stateDFU = UpdateProcessStates.UpdateProcessStatesFailed;
      print(e.toString());
    }
  }

DFU CHARACTERISTICS NOT FOUND

Hi, I'm having a problem with something, the package it seems.
I try to do the ota and it always fails with DFU FAILED: DFU CHARACTERISTICS NOT FOUND on both iOS and Android.
It works through nrf connect.
I can see the service being discovered by other ble packages.
No idea what might be wrong.

(I have tried setting enableUnsafeExperimentalButtonlessServiceInSecureDfu to true)

            throw BluetoothException('Error occured when pairing the device');
          },
        );
      }

My problem here is that after putting the device into update mode, it disconnects from the phone, AND the NordicDfu().startDfu() doesn't print anything, i can't tell if the state of the device.
meaning I can't update it successfully. how can I achieve my goal?

sending information from kotlin to flutter

I am currently using your plugin locally and trying to integrate it into an app that I am currently developing. The DFU update is working and I can read print statements that I inserted into the kotlin code in the debug console. However, unlike when I run the example app, the progressListener messages are not observable in the debug console and print statements that I put in the setMethodCallHandler are not being executed. I put print statements around invokeMethod in NordicDfuPlugin.kt and the debug console detects it. I am not sure if this is a thread issue. I am currently testing using an Android 12 phone and VSCode.

Is it possible to help me with this? Thank you very much!

Error on build app

Hello, when I try to run the production build, I get the following error:

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':nordic_dfu:compileReleaseJavaWithJavac'.
error: invalid source release: 17

The version of Flutter we are using is the following, using FVM:

[✓] Flutter (Channel stable, 3.0.5, on macOS 13.4.1 22F770820d darwin-arm, locale it-IT)

How can I resolve this issue? Because when I remove your plugin, it works correctly 😅

Aborting dfu mid-update doesn't immediately disconnect from peripheral

Using version 6.4.1+hotfix
Using an Android device with a connection to a ble peripheral

Running into an issue:

NordicDfu().abortDfu() called mid update as a user would like to cancel the update
onDfuAborted callback received, so the update has successfully aborted and is no longer sending packets
Dfu maintains it's ble connection for about a minute before finally disconnecting

Am I correct in assuming that the ble connection should be severed immediately after a successful abort, or is the behavior I'm seeing intentional?

DFU Abort Programatically

hey , can we abort Dfu programatically ??

Problems in disconnected situations due to distance during update

During the update process, we intentionally widened the distance and created an update not possible situation.
The message "Disconnecting..." remains on the top of the cell phone and appears to be waiting indefinitely.
At this time, when you exit the app, it ends together.
NordicDFU seems to fall into an infinite loop while disconnecting from a Bluetooth device, is there a solution?
I used the latest version of 6.0.1.

Nothing happens when calling startDfu

Hey,
I'm trying to implement the plugin in the most basic way but I get no logs and my callbacks are not called.
What might be the problem?

This is my implementation:

if (selectedDfuPath == null) {
                          Fluttertoast.showToast(msg: 'no file selected');
                          return;
                        }
                        String? address = device.getMacAddress();
                        if (address == null) {
                          Fluttertoast.showToast(msg: 'mac address is null');
                          return;
                        }
                        NordicDfu().startDfu(
                          address,
                          selectedDfuPath!,
                          onProgressChanged: (String address,
                              int percent,
                              double speed,
                              double avgSpeed,
                              int currentPart,
                              int totalParts) {
                            setState(() {
                              dfuProgress = percent;
                            });
                          },
                          onDfuCompleted: (String address) =>

Abort DFU is not working if we manually triggers that abortDFU() function

Its throwing platform exception in android devices

Unhandled Exception: PlatformException(6, DFU FAILED: Operation failed, Address: 6D5C4F40-C754-57D4-9D6A-DE57DC88B15F, Error type 6, null)

Plugin version: 6.1.0
Flutter version: 3.10.4 • channel stable

I can update the firmware using nRF iOS app but not with my Flutter iOS app.

In nRF iOS app I had to set the following parameters to successfully do the DFU:

Allow Resuming DFU: true
PRN(s): 5
Data Object Preparation: 0.3s
Enable Alternative Advertising Mode: true
Force DFU: true
Enable Experimental Buttonless DFU: false

In my Flutter app I have the following function that tries to replicate mostly the above parameters:

Future<void> startDFU() async
  {
    await NordicDfu().startDfu(
      widget.deviceID,
      'assets/20230727.zip',
      numberOfPackets: 5, //I assume this is same as PNR(s)
      forceDfu: true, 
      onProgressChanged: (
          deviceAddress,
          percent,
          speed,
          avgSpeed,
          currentPart,
          partsTotal,
          ) {
        print('deviceAddress: $deviceAddress, percent: $percent');
      },
    fileInAsset: true,
        onDfuCompleted: handleDfuCompleted,
        onDfuAborted: handleDfuAborted,
        onDfuProcessStarted: (String deviceAddress) =>
            print("DFU PROCESS STARTED"),
        onDeviceConnected: (String deviceAddress) =>
            print("DEVICE CONNECTED"),
        onDeviceConnecting: (String deviceAddress) =>
            print("DEVICE CONNECTING"),
        onDeviceDisconnected: (String deviceAddress) =>
            print("DEVICE DISCONNECTED"),
        onDeviceDisconnecting: handleDeviceDisconnecting,
        onDfuProcessStarting: (String deviceAddress) =>
            print("DFU PROCESS STARTING"),
        onEnablingDfuMode: (String deviceAddress) =>
            print("ENABLING DFU MODE"),
        onFirmwareValidating: (String deviceAddress) =>
            print("FIRMWARE VALIDATING"),
        onError: handleError,);
  }

Is there any plan to add `Windows` support?

I want to build it for Windows application which can use OTA firmware update.

Is there any plan to add Windows support?

Or, what should I do for implementing DFU via ble in Windows.

Starting DFU does nothing after update failed

Hello,

I got a problem using this library. When I am launching NordicDfu().startDfu(...) and then unplug the Nordic board, I am unable to relaunch DFU update until I completely kill and restart the application...

Here is the code used to launch DFU:

import 'package:flutter/material.dart';
import 'package:flutter_blue/flutter_blue.dart';
import 'package:nordic_dfu/nordic_dfu.dart';
import 'package:poc_ble/DevicePage/BottomSelectUpdate.dart';
import 'package:poc_ble/Logger/CustomLogger.dart';

class BottomLaunchUpdate extends StatefulWidget {
  const BottomLaunchUpdate(
      {Key? key, required this.deviceId, required this.firmware})
      : super(key: key);
  final DeviceIdentifier deviceId;
  final UpdateFirmwareType firmware;

  @override
  State<BottomLaunchUpdate> createState() => _BottomLaunchUpdateState();
}

  bool _dfuHasError = false;

  String getFilePath() {
    customLogger.d("GETTING FILE PATH for ${widget.firmware}");
    switch (widget.firmware) {

              const Text("Updating...", style: TextStyle(fontSize: 30)),
              const SizedBox(height: 20),
              LinearProgressIndicator(value: _progress / 100),
              const SizedBox(height: 20),

              ),
            ],
    );
  }
}

Can I have some more information of what I can do to solve this? Thanks!

Dfu device find by Name instead of ID

Hey can we do something like Start Dfu for a device with a custom Name , actually what happens is My Device id changes when it enters to Bootloader mode , so only thing i can do is change its name when enter to bootloader ,
and scan for all available device , get the device with that name , grab its id , and pass that id to this package

But can we do something like this with this package , like we can pass another parameter of custom name and deviceId ( OrignalId before Entering to Bootloader), later things can be handled by this package

basically in Android i can achive this by another Approach ,
for Example my device advertising in android
with id D5:59:39:3B:B3:59
and when its in Bootloader. its advertising with ID : D5:59:39:3B:B3:5A

so basically adding 1 to the orignal Hexadecimal d559393bb359 + 1 => d559393bb35a
which is working fine , but for ios , no idea how to achieve this ,
like in case of IOS ,
Device ID : 6D8D8DC9-BA02-430F-4DC7-572E057D801B
DFU ID : 8100EEB2-F871-239E-80C2-03C03F613E58
Any Idead how can we detect in this case , or by adding 1 to DeviceID somehow can get us DfuID ??

Android very slow

Hello,

Library is great, thank you!
But Android is very slow. Any chance to requestConnectionPriority that will speed it 5 times?

Thank you very much

Looks like this line needs to be replaced:

val rebootTime = call.argument<Long>("rebootTime")

With this one:

val rebootTime = call.argument<Int>("rebootTime")?.toLong()

Hi, thank you for supporting and updating this library!
Is it possible to have the option to negotiate an MTU when performing the Device FIrmware Update?

DFU Never Finishes

I am having an issue with the nordic dfu service finishing. I have been using the flutter_nordic_dfu package for a while now with great success but since Android 12 has been released I have had to move to nordic_dfu. The dfu starts and in my on progress listener, I am printing out the percent. It will print out from 1% to 100% but then does nothing. My progress indicator shows that it has large jumps from 0 to 30 to 50 to 80 then 100 then stays at 100. The time it takes from 0% to 100% is only about 10 seconds when normally it would take about a minute and 30 seconds. After a couple of minutes at 100% the app will crash.

I am testing on a Google Pixel 6 with Android 12 and a Samsung Tab A with Android 11 and getting the same results.
I can put this same code on an iPhone and it performs like it should and always has.

Can you give me an idea why this might be happening and how i could fix it.

Thank you.

iOS App report [Unhandled Exception: PlatformException(DEVICE_ADDRESS_ERROR, Device address conver to uuid failed, Device uuid EE:01:06:81:63:3E convert to uuid failed, null】 Error

1.This is the remote device related information in iOS&Android

iOS print:DiscoveredDevice(id: 62CCCBCA-5C14-2CEA-8DCA-F8E91FB993C8, name: DZ29_633E, serviceData: {7364: []}, serviceUuids: [], manufacturerData: [105, 108, 2, 21, 238, 1, 6, 129, 99, 62], rssi: -61, connectable: Connectable.available)

manufacturerData -> macid: 69:6C:02:15:EE:01:06:81:63:3E. We chose the last six！

2.This is what I use in flutter
await NordicDfu().startDfu(

'assets/a.zip',
fileInAsset: true,
onProgressChanged: (
deviceAddress,
percent,
speed,
avgSpeed,
currentPart,
partsTotal,
) {
Logs.prints('deviceAddress: $deviceAddress, percent: $percent speed = $speed avgSpeed = $avgSpeed currentPart = $currentPart partsTotal = $partsTotal');
},
);
2.This is an error message in ios
Unhandled Exception: PlatformException(DEVICE_ADDRESS_ERROR, Device address conver to uuid failed, Device uuid EE:01:06:81:63:3E convert to uuid failed, null)

3.This is Android working properly

Uploading firmware...

Last version won't build for IOS

I tried to update the package to 5.1.0.
No issue on Android, but IOS won't build.
I get the following print :

Could not build the precompiled application for the device.

Anybody has the same issue ?

nRF53 support

Any plans?

Constant DFU_FIRMWARE_NOT_FOUND error

I'm running the most up-to-date versions of flutter as well as versions of this package.

I'm making my call like this:

 onPressed: () async {
                              final notifier =
                                  ref.read(firmwareNotifierProvider.notifier);
                              final path = await notifier.getFirmwarePath(
                                  latestFirmware.downloadUrl ?? '');
                              print('Firmware path: $path');
                              print('Device remoteId: ${uiState.remoteId}');
                              await NordicDfu().startDfu(
                                uiState.remoteId,
                                path,
                              );
                            },

Where path is set by downloading a .zip file from Firebase and placing it in a temp directory:

Future<String> getFirmwarePath(String url) async {
    // Get the temporary directory
    Directory tempDir = await getTemporaryDirectory();
    // Define the local file path
    String filePath = '${tempDir.path}/file.zip';

    // Use Dio to download the file
    Dio dio = Dio();
    await dio.download(url, filePath);

    if (await File(filePath).exists()) {
      print('Download successful, file is where it should be.');
      return filePath;
    } else {
      throw Exception("Download failed, file's not in the temp directory.");
    }
  }

I received a path back and it appears that half works correctly. The problem is when calling the .startDfu() it fails 10/10 times. I receive this error:

The content of my .zip file is a .bin file named app_update.bin and a manifest file called manifest.json I've tried just passing the .bin file and that fails too. I've tried putting my zip file into assets and going that route and it still fails. I've tried using my .zip file with NRF connect and it works flawlessly. I'm not sure why this is happening here because the error message isn't explicit enough in what it is trying to portray.

Any help is much appreciated.

Connect SDK w/o nrfutils ?

Can I use this library for firmware with nrf connect sdk?

When I build the firmware, a -zip is available, but the file does not work:

This is my code this is showing the error No implementation found for method startDfu on channel dev.steenbakker.nordic_dfu/method

DFU Transfert is working but No callback is never called.

I'm using the DFU, and the transfert works fine.
The only problem is : the call back are NEVER called, which means my app has NO WAY of nowing if/when the transfert is done.
With the prints, I see that it's going fine, but I'm wondering how Can I get these infos on my app ...

I use a Samsung A3 with Android 8, but I tried as well with a Pixel 4A 5G with Android 12 and I have the same issue.
I use Flutter 3.

Here is how I start the DFU :

await NordicDfu().startDfu(deviceID, file, fileInAsset: true,
    onDfuCompleted: (e){print("[DFU] Completed, $e");},
    onDeviceDisconnected: (e){print("[DFU] DIsconnected, $e");},
    onError: (e,a,b,c){print("[DFU] ERROR $e, $a, $b, $c");},
    onDfuAborted: (e){print("[DFU] Aborted $e");},
    onProgressChanged:(
        deviceAddress, percent, speed, avgSpeed, currentPart, partsTotal) {
          progressListener.progress(percent);
          print('[DFU] $percent%');
    });

All my prints I never done.
I still know it is working thanks to the console output :

Does any one has any idea to get the call back to work, or even just a workout to get info on how the transfert is going on ? I thought of rerouting the console output, but no idea on how to do that...
Thanks a lot !

nRF Connect SDK + Android-nRF-Connect-Device-Manager

Are there any plans to implement the new Android nRF Connect Device Manager library for Nordic DFU?

If not, do you have any advice about how to do that in a fork? Or would it be better to start from scratch?

Need implementation for `setRebootTime(long)` method

In order to resolve this issue, we need to implement the function setRebootTime(long) in this library. Using this function, we will be able to delay the device reboot by the provided milliseconds.

Here is the code for the above-said function in the official Android-DFU-Library:

https://github.com/NordicSemiconductor/Android-DFU-Library/blob/b37200033f5d3fe412994e05dd20dd57e14acfe5/lib/dfu/src/main/java/no/nordicsemi/android/dfu/DfuServiceInitiator.java#L299-L302

The expectation is to have a parameter inside both AndroidSpecialParameter and IosSpecialParameter class as follows:

firmwareUpdater.startDfu(
    androidSpecialParameter: AndroidSpecialParameter(
        rebootTime: 1000, // Time (int) in millis
    ),
    iosSpecialParameter: IosSpecialParameter(
        rebootTime: 1000, // Time (int) in millis
    ),
);

Could you please help with this @juliansteenbakker?

Android not working, while works fine in iOS, BLE device is nRF 52840

Android upload is excessively slow because uploadPacketDelay is set to 400ms.

https://github.com/juliansteenbakker/nordic_dfu/blob/master/android/src/main/kotlin/dev/steenbakker/nordicdfu/NordicDfuPlugin.kt#L120 unconditionally sets 400ms inter-packet delay, which severely slows down the firmware upload. Please remove or allow configuration.

Infinite loop on DFU

Hello,

I've been trying to use flutter_nordic_dfu to DFU my NRF52 device without any success.
I tried your library and I'm getting the same result:

When running a simple DFU using a Firmware homemade.
The firmware DFU is working fine with NRF Connect, but I need to turn Alternative Advertising Mode off.

5E5B33DD-07EC-020F-639B-4FCB80E3763A onEnablingDfuMode

For an unknown reason it's just looping on this. Any idea why ?

dfu isn't starting or starting late

nordic dfu app can update the device but this library cant update. Logs below. These events keep happening consistently, resulting in either not starting or starting late. i added reboot time but it didnt work
