laerdal / laerdal.dfu Goto Github PK

Hi @framinosona ,
I continue with the plugin tests and when I try to access the Progress property I get the error:
System.InvalidCastException: 'Specified cast is not valid.'

The FW update continues but no longer updates the screen.

Thanks

Maria

Hi, when I tried submitting the app to App Store Connect, I got this error:

ERROR ITMS-90206: "Invalid Bundle. The bundle at 'Fliteboard.iOS.app/Frameworks/ZIPFoundation.framework' contains disallowed file 'Frameworks'."

ERROR ITMS-90206: "Invalid Bundle. The bundle at 'Fliteboard.iOS.app/Frameworks/iOSDFULibrary.framework' contains disallowed file 'Frameworks'."

I tried that known issue's solution xamarin/XamarinComponents#993, but unfortunately it didn't fix the problem.

Also, I notice that the app size is way bigger than the previous builds after I added this library. It grows from 32MB to 220MB, is there a way to trim the build?

Describe the bug
I'm implementing the functionality to upgrade a firmware using DFU but it throws an exception when executing DfuInstallation.Start().

I've declared the Foreground Service permission on AndroidManifest.xml and a Foreground service link but it's still throwing the error.

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

To Reproduce
Steps to reproduce the behavior:

1. Create a MAUI project (NET 8)
2. Install the Laerdal.Dfu 1.27.8 NuGet package
3. Include the Foreground Service permission on AndroidManifest.xml.
4. Implement a Foreground service.
5. Create a method to download or retrieve your firmware update file.
6. Scan for the desired device to DFU.
7. Create the DfuInstallation object and call Start().

Expected behavior
Start and complete the DFU process with the BLE device.

Desktop:

• OS: Mac 14.1.1 (23B81)
• IDE: VS Mac 17.6.7 (build 417)
• NuGet package Laerdal.Dfu version 1.27.8
• NET Maui v8.0.100

Smartphone:

• Device: Samsung A53
• OS: Android v13

Describe the bug
Device firmware update works for android but fails for iOS as soon as I call Start() method on Laerdal.Dfu.DfuInstallation instance.
To Reproduce
Steps to reproduce the behavior:

1. Add Laerdal.Dfu 1.25.2 in shared project, android project and iOS project
2. Call StartDfu which is implemented as:

  public async Task StartDfu()
        {
            var updater = new Laerdal.Dfu.DfuInstallation(_deviceId, _embeddedDfuFile);
            updater.Start();
        }

Expected behavior
The device firmware process should start successfully as it does in android.

To Reproduce
Steps to reproduce the behavior:

1. Open Visual Studio and create a .NET MAUI APP
2. Install Laerdal.DFu v1.20.15 installed via Nuget
3. Rebuild solution

Desktop (please complete the following information):
Microsoft Visual Studio Community 2022 (64-bit) - Version 17.3.3
Windows 11 Pro

Describe the bug

I tried to implement the DFU on a .NET MAUI application, but it seems that when I create the DfuInstallation object and call the Start() function the process throws an Exception with a message:
Exception of type 'Foundation.You_Should_Not_Call_base_In_This_Method' was thrown.

To Reproduce

Steps to reproduce the behavior:

1. Create a MAUI project
2. Install the Laerdal.Dfu 1.27.8 NuGet package
3. Create a method to download or retrieve your firmware update file
4. Scan for the desired device to DFU
5. Create the DfuInstallation object and call Start()

To download the firmware File:

public async Task<bool> DownloadFirmwareFile()
{ 
    //Retrieve firmware file in bytes 
    byte[] fileBytes = await HttpClientService.Instance.GetByteArrayAsync(Constants.GetFirmwareUpdate);

    //Create the file inside LocalApplicationData
    string outputFilePath = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "app_dfu_package.zip");

    File.WriteAllBytes(outputFilePath, fileBytes);

    //Check if the file exists and update the SelectedFirmwareFile
    var exists = File.Exists(outputFilePath);
    if (!exists)
    {
        Instance.SelectedFirmwareFile = null;                            
        return false;
    }
    else
    {
        Instance.SelectedFirmwareFile = new FileInfo(outputFilePath);
        return true;
    }
}

To launch the update process:

var deviceId = $"{Instance.SelectedDevice?.Id.ToString()}";
var filePath = $"{Instance.SelectedFirmwareFile?.FullName.ToString()}";

var fileExists = File.Exists(filePath);
Debug.WriteLine($"File path exists: {fileExists}");

var output = new DfuInstallation(deviceId, filePath);

output.DfuErrorReceived += DfuInstallationOnErrorOccured;
output.DfuStateChanged += DfuInstallationOnStateChanged;
output.DfuProgressChanged += DfuInstallationOnProgressChanged;

output.Start();

FileUrl value: /var/mobile/Containers/Data/Application/537D36A3-7D6D-4A0F-B78A-8A03F85CEFEF/Documents/app_dfu_package.zip

Expected behavior

Start and complete the DFU process with the BLE device.

Additional context

I've tried to recreate the exception on Android 12, but the debugger gets disconnected when reaches the start command.
(I am using wireless debug, due to maui issues #16274.

Is there an active example on MAUI I can follow?

Hello, thanks for creating this awesome library, it really saves my life : )
Just want to know would it provide connection timeout option in the future versions? Looks like the current version will wait for the device to enter bootloader mode without timeout, it would be good to trigger a timeout error so that the app can show a warning dialog to the user.

Describe the bug
EnableUnsafeExperimentalButtonlessServiceInSecureDfu parameter has no effect on iOS.

Looking at /Laerdal.Dfu/iOS/DfuInstallation.cs, line 60:

// EnableUnsafeExperimentalButtonlessServiceInSecureDfu
if (EnableUnsafeExperimentalButtonlessServiceInSecureDfu.HasValue)
    Initiator.ForceScanningForNewAddressInLegacyDfu = EnableUnsafeExperimentalButtonlessServiceInSecureDfu.Value;

It should be:

// EnableUnsafeExperimentalButtonlessServiceInSecureDfu
if (EnableUnsafeExperimentalButtonlessServiceInSecureDfu.HasValue)
    Initiator.EnableUnsafeExperimentalButtonlessServiceInSecureDfu = EnableUnsafeExperimentalButtonlessServiceInSecureDfu.Value;

Describe the bug
When I run the Sample project on iOS, an exception gets thrown when I try to search for a device.
The exception doesn't seem to load, but shows Foundation.MonoTouchException: 'Loading...'

To Reproduce
Steps to reproduce the behavior:

1. Clone repo and checkout develop branch
2. Run the sample on a connected iPhone device
3. Push the section with "No device"

Expected behavior
I get a list of availble DFU-ready devices

Desktop (please complete the following information):

• OS: Windows
• Browser Edge
• Version 91.0.864.67

Smartphone (please complete the following information):

• Device: iPhone 11
• OS: iOS 14.6
• Browser Safari
• Version n/a

Additional context
I should also note that when running the app in debug mode, I am unable to hit any breakpoints other than the static void Main in Main.cs of the iOS project.

We've been having issues archiving iOS apps that reference an iOS library that imports the Laerdal.Dfu package. Although when the code from the library project is copied into the app, the archiving issues are resolved.

[iOS App] -> [Laerdal.Dfu] = (OK)
[iOS App] -> [iOS Library] -> [Laerdal.Dfu] = (Archiving issues)

To Reproduce
Steps to reproduce the behavior:

1. Open the following solution sample-dfu-app.zip
2. Set the build configuration to Release
3. Archive the sample-dfu-app-import.iOS project which refers to the Laerdal.Dfu package via the dfu-iOS library.
4. You should get the following error:

Target "_SRSCopySwiftSupport" in file "/Users/carl/.nuget/packages/xamarin.ios.swiftruntimesupport/0.2.0/buildTransitive/Xamarin.iOS.SwiftRuntimeSupport.targets":
  Task "Message"

  Done executing task "Ditto" -- FAILED.
Done building target "_SRSCopySwiftSupport" in project "dfu-iOS.csproj" -- FAILED.
Done building project "dfu-iOS.csproj" -- FAILED.

5. Archive the "sample-dfu-app.iOS" project which refers to the Laerdal.Dfu package directly.
6. You should get an error related to the provisioning profile, which means ditto process ran successfully during the build.

Expected behavior
The ditto process should run successfully when building the iOS library for an archive.

Additional Context
Note that it's only when building for an archive that this happens. Building for a debug run works without any issue.

I'm not sure whether this is something that can be fixed by this you guys, but if you have any idea on how I can fix this, it'd be appreciated.

Work Around
Reference to the code directly in the iOS app project. Don't use a library project.

Describe the bug
Project in xamarin forms with ble.net, when calling start in iOS, the following exception is thrown:

"Exception of type 'Foundation.You_Should_Not_Call_base_In_This_Method' was thrown."

obs: Need guidance in case i'm missing something to setup the dfu correctly in iOS, because the same exception is not happening in Android. The process starts ok

Hello, it seems that the library doesn't work properly on Android 12, it fails to find the DFU target and starts the update process, but it is working well on older Android versions. I tried adding new Bluetooth permissions for Android 12, but still the same.

Is your feature request related to a problem? Please describe.
Yes, the latest android release requires a PendingIntent to provide a Mutable or Immutable flag, which has been added by the Nordic Library (NordicSemiconductor/Android-DFU-Library@050f788) 3 months ago. Without this change the application crashes.

Describe the solution you'd like
Build a new NuGet package taking into account the Nordic Library with Android 12 support

Describe alternatives you've considered
I tried building a NuGet myself, but the build.sh crashed on not being able to find a directory after the msbuild command.

Describe the bug
I use the version 1.25.2 in my Xamarin.Forms project
The Android version works fine, but the iOS can't build

To Reproduce
Steps to reproduce the behavior:

1. Add version to 1.25.2 .net type of project
2. I connect from the Visual Studio to the macbook
3. I try to build a iOS-project

Describe the bug
After device and file are chosen and settings are selected, the app crashes after hitting start. The error is "Objective-C exception thrown. Name: NSInvalidArgumentException Reason: -[iOSDFULibrary.DFUFirmware initWithUrlToZipFile:]: unrecognized selector sent to instance 0x282f4f020

To Reproduce
Steps to reproduce the behavior:

1. Use Version 1.20.15
2. Implement bindings into application
3. Click start update
4. See error

Expected behavior
Zip file is sent to device and firmware is updated

Additional context
I have the sample application in my GitHub. It is for business operations, so I cannot make public, but am willing to share to resolve this issue

Describe the bug
I'm trying to retrieve my firmware update package using API request from my server, but when i call DfuInstallation.Start(); it throws a DFU FILE NOT FOUND, DfuError = 4097

I can't understand the difference between the picker path and the PickFileAsync() with the CopyFile() and my approach using a web API.

How can I use a dfu_package.zip file (from a web API) with the Laerdal.Dfu in order to update the firmware?

Attempts

1. I've tried to call the CopyFile() function after the File.WriteAllBytes(outputFilePath, fileBytes); (To Reproduce step 2)
2. I've tried to use a different file paths

• System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal)
• System.Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData)

To Reproduce
Steps to reproduce the behavior:

1. Install Laerdal.Dfu version 0.7.0
2. Create a DownloadFirmwareFile function

public async Task<bool> DownloadFirmwareFile()
        { 
                //Retrieve the file from the API
                HttpClient client = new HttpClient();
                var url = "**APPLICATION_API**";
                byte[] fileBytes = await client.GetByteArrayAsync(url);

                //Create the file inside LocalApplicationData
                string outputFilePath = Path.Combine(FileSystem.AppDataDirectory, "dfu_package.zip");
                File.WriteAllBytes(outputFilePath, fileBytes);

                //Check if the file exists and update the SelectedFirmwareFile
                var exists = File.Exists(outputFilePath);
                if (!exists)
                {
                    SelectedFirmwareFile = null;
                    return false;
                }
                else
                {
                   // var newFilePath = await CopyFile(new FileResult(outputFilePath));
                   // if (!string.IsNullOrEmpty(newFilePath))
                    //    SelectedFirmwareFile = new FileInfo(newFilePath);
                    SelectedFirmwareFile = new FileInfo(outputFilePath);
                    return true;
                }        
        }

3. Use the SelectedFirmwareFile inside the GetDfuInstallation() function in order to create the DfuInstallation object

   private static DfuInstallation GetDfuInstallation()
        {
            var deviceId = $"{NativeDeviceIdHelper.GetIdFromNativeDevice?.Invoke(SelectedDevice?.NativeDevice)}";
            var filePath = $"{SelectedFirmwareFile?.FullName}";
            var output = new DfuInstallation(deviceId, filePath);

            output.ErrorOccured += DfuInstallationOnErrorOccured;
            output.StateChanged += DfuInstallationOnStateChanged;
            output.ProgressChanged += DfuInstallationOnProgressChanged;

            return output;
        }

4. Call the DfuInstallation.Start();
5. The device information inside the DfuInstallation object is correct
6. The file exixists File.Exists(outputFilePath);
7. The error message is DFU FILE NOT FOUND

Expected behavior
Launch the DFU process

Additional context
The path of my file is "/data/user/0/com.aidplex.backbrace/files/dfu_package.zip"

The size of the ipa file when we build our Xamarin Forms app for iOS is quite large. Our app almost doubled in size.

Before including laerdal.dfu the ipa size was 34.3MB
After including it the size has grown to 66.8MB

The numbers above are with link behaviour set to framework SDKs only. If I use link everything instead, the size is 62.7MB, which is a little smaller but still much larger than originally.

These numbers are with the latest version of the library (v0.3.0)
For reference: On Android, the app only grows with approx 200kB.

It would be great if it was possible to reduce the size of the library on iOS.

Describe the bug
When trying to start an update with DFU a SecurityException is thrown.

Java.Lang.RuntimeException: Unable to create service crc640fd658db7faaed21.DfuServiceDelegate: java.lang.SecurityException: com.appid: One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts

To Reproduce
Steps to reproduce the behavior:

Call the Start method for the DFU installation:

var installation = new DfuInstallation(deviceId, file);
installation.Start(new DfuConfiguration());

Expected behavior
Update with DFU should start.

Smartphone:

• Device: Google Pixel 6
• OS: Android 14

Additional context

As far as I understand this happens only if the target SDK level is at 34 and your phone has Android 14 installed.
Looks like an issue with the Android Nordic library NordicSemiconductor/Android-DFU-Library#412 maybe it is already fixed with an update.

I am running into an issue with running a DFU Update on an Android 14 device. This is the log of the error.

It says I am starting a Foreground Service without a type. Is this something I need to declare in the Manifest? I already have the ForeGround Service added in my Manifest, but it seems there has a been a change with Android 14 to need a type as well. Just wondering if anyone knows the exact type to add to fix this issue?

Describe the bug
Hey guys :)

Looks like their might be a slight bug with the constructor new DFUFirmware(NSUrl urlToZipFile). When I try to use this function with any of the nugets >=0.2.17, I get this error:

Foundation.MonoTouchException > Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: -[iOSDFULibrary.DFUFirmware initWithUrlToZipFile:]: unrecognized selector sent to instance 0x283e51220

To Reproduce
Steps to reproduce the behavior:

1. Use the new DFUFirmware(NSUrl urlToZipFile) anywhere in an iOS app with the latest nuget package v1.20.15. Even if the file path doesn't point to a valid DFU file, it doesn't matter. E.g. new DFUFirmware(NSUrl.FromString("file:///var/somefileondevice.zip"));
2. You should get an Name: NSInvalidArgumentException Reason: -[iOSDFULibrary.DFUFirmware initWithUrlToZipFile:]: unrecognized selector sent to instance error.

Expected behavior
The DFUFirmware class instance gets created or throws another error like Invalid DFU file content.

Additional context
Note that this works perfectly with v0.2.16-beta0012. I think v0.2.17 included a change to a new version of the Nordic library as stated here.

It took me a while to track down this error to a possible bug in the Laerdal.Dfu library. I had to make sure it wasn't an error in my project configuration.

If you look at the definition of the DFUFirmware constructor in the Xamarin code:

And the in the ObjectiveC Binding:

And finally in the actual Nordic library:

It looks to me like the move from NSUrl to the new Swift construct URL may have broken the binding.

It's just a theory of course. It would be great if you guys could investigate and let me know if you find the issue. I'd love to jump on the v1.20.x version which may be more stable and complete. At the same time, v0.2.16 works for our current needs so there is no rush.

Thanks again for this binding library.

Cheers

Describe the bug
When I try to do a DFU update in iOS, I get a Could not obtain peripheral instance BluetoothDisabled error. The dfu installation goes through the connecting state but immediately errors out. Bluetooth is enabled, the address is valid, and so is the file path. There appears to be something similar to https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library/issues/256 but they are developing directly in swift / objective-c.

To Reproduce
Steps to reproduce the behavior:
dfuInstallation = new Laerdal.Dfu.DfuInstallation("00000000-0000-0000-0000-ccdc94eb087e", "var/mobile/Containers/Data/Application/17764959-22A4-4C19-A02B-62C1EF23E20B/Documents/.config/Sdk14_nRF52_v37p14_APP_pkg.zip");
dfuInstallation.PropertyChanged += Dfu_PropertyChanged;
dfuInstallation.ErrorOccured += DfuInstallation_ErrorOccured;
dfuInstallation.ProgressChanged += DfuInstallation_ProgressChanged;
dfuInstallation.StateChanged += DfuInstallation_StateChanged;
dfuInstallation.Start();

Expected behavior
I would have expected the app to work the same as the android version (which updates fine);

Hi @framinosona ,

I am testing the nuget package version 0.2.1 in a Xamarin Forms project to perform FW update on a BLE device and when it tries to parse the zip file it gives the following error:

I try this:
DfuInstall = new DfuInstallation(deviceId, fichero.FullPath);
DfuInstall.Start();

The truth is that I don't know if I am implementing it well.
Could you add a small example ?

Thank you very much
Maria

Any chance someone has updated this library to .NET 6 and supporting .NET MAUI (net6.0-android and net6.0-ios)? Is this on the roadmap at all @framinosona?

We've made an attempt at rewriting some of the binding library to handle this on Android in MAUI (and it works!) but we can't get the iOS version working (crashes out when starting the flashing process DFUInstall). We're not iOS developers so are a little out of our depth on it. Any help appreciated!

Hi @framinosona ,

Here I am again... :)

Testing on iOS I get the following error:
Could not initialize an instance of the type 'Laerdal.Dfu.iOS.DFUFirmware': the native 'initWithUrlToZipFile:' method returned nil.Could not initialize an instance of the type 'Laerdal.Dfu.iOS.DFUFirmware': the native 'initWithUrlToZipFile:' method returned nil.

I am testing in Visual Studio for Mac( 8.8.10 ), with an iPhone X (iOS 14.4.1).
I have the FW file on the device, not on a server.

Thanks
