Hi Adrian,

Thanks for the fast reply.

I am making a Xamarin Forms app for Android and iOS. And I only need the DFU part, because I already have a BLE adapter.

Sorry to hear that the source code is't available. I am already working with a nice free BLE library.

Regards,

Ragnar

Hi Ragnar

The DFU library we made available for the public two years ago was written for the legacy bootloader. As you are using SDK 12 I assume that you are using the new signed DFU from Nordic.

The signed DFU with support for Zip-Files with bin and dat files was added in later versions of the DFU-library. The newer versions of the DFU library‘s are not public up to now. I guess that it would be ok to make the binary version of the DLL available that can be used with our commercial product BLE Library. The source will remain closed as we have seen that the code was taken and modified to be used with free libraries.

What platforms are you triing to run Nordic DFU? Our library can provide a common BLE functionality for iOS,Android und Microsoft Windows with Silicon Labs BLED 112 Dongle.

Hi Adrian Eggenberger,

I have looked at you DFU library alone, amazing..!

But I have some questions. The device we use, does not have a DFU revision uuid. (I am using SDK v12)

Can this DFU library use zip file, with bootloader, application (dat and bin files) and so on..? or only HEX files..?

Thanks in advance

Ragnar

Adrian has the DFU library you converted been updated to support encrypted files? Browsing through your work, and @Shay Ohayon's, it would appear the library doesn't support .zip files and encrypted files. Please advise. Thank you very much

Fantastic. Looks like you guys translated the original Nordic native implementation to C#. This is exactly what I was searching for. Adrian - thank you so much for sharing this!

Wow..... And you opened source code. Don't know what to say. Thanks. have a good weekend!

Adrian Eggenberger — Sun, 28 Aug 2016 08:54:57 GMT

That's right. There is no binding to any code or library from nordic. The implementation is completely written based on the protocol description. And yes it was a big effort making it work. :-)

benevbright — Sun, 28 Aug 2016 08:51:24 GMT

If yes, It should be a lot a work, I didn't even think it would be possible.

THis is just awesome.. I will have to try it soon. But I want to say thank you first. Quick question, I looked code and noticed there is no binding with Native framework from Nordic but recoded it by using c#. Is that correct?

I've now modified the library code and replaced the binary library with source code in the shared project. Cheers Adrian

Hi, Adrian. Thanks for your answer.

Hi Shay, I guess that the code for the library will be available in the next week. Adrian

Hi benevbright, As I wrote above the DFU implementation depends on the Arendi.BleLibrary. This was important to us to avoid a platform specific implementation for the BLE services. So there is no way to use the DFU library with the nativ Android or iOS Bluetooth objects. The used read/write operations are completly different for Android and iOS and in our implemenation they are handled by the Arendi.BleLibrary. If you need to use another BLE library you probably need to adapt the Nordic Andoird DFU library or our implemenation (as soon as I've the code for the library ready). Adrian

On that note - any news regarding release the code for the DFU library?

RE: DFU in iOS Xamarin

benevbright — Thu, 25 Aug 2016 17:12:41 GMT

Hi, Adrian. I tested that great example. DFU works great. But I can't use it without Arendi's BLE library. The method that request DFU named "Update" require IPeripheral class which is in Arendi's BLE library. I'm using other BLE library. This library also has its Peripheral class but casting is not working. Could you ask to your engineer about this problem and how to solve? Thanks so much.

Wonderful. Having the source code for that library would make this super useful. Many thanks for your efforts Adrian!

Adrian Eggenberger — Mon, 22 Aug 2016 13:06:33 GMT

I assume it will be possible to release the library source as well, but it needs some modification before it is possible to release it to the public.

I've tomorrow commited some modification of the iOS project. There was a failure at the included files which I didn't see at the weekend (I've no iOS development environment at home).

I'm curious too. Thanks.

Shay Ohayon — Sat, 20 Aug 2016 14:14:59 GMT

Adrian, is the source code for Arendi.BleLibrary.Service.NordicDFU available, or only the dll?

RE: DFU in iOS Xamarin

benevbright — Sat, 20 Aug 2016 13:22:43 GMT

It's awesome. really appreciate. Everything seems pretty good. I will try it soon.

RE: DFU in iOS Xamarin

Adrian Eggenberger — Sat, 20 Aug 2016 11:50:14 GMT

Good luck! I hope I've comited everything required. If you've got problems just ask.

RE: DFU in iOS Xamarin

Shay Ohayon — Sat, 20 Aug 2016 11:32:01 GMT

Awesome. I'll check it out today!

Hi Folks,

It took some time and I had to do some adaptions but it's working now. I've setup a public Git repository at Bitbucket. The repository includes a Xamarin project for iOS and Android. Feel free to comment and propose changes for upcoming releases.

Nordic DFU with Xamarin (Android & iOS)

This repository shows a demo app of the Nordic DFU implementation on Xamarin.

Git: https://bitbucket.org/arendiag/arendi_nordicdfu.git

Web: https://bitbucket.org/arendiag/arendi_nordicdfu/overview

Components

Arendi.BleLibrary.Service.NordicDFU

This library provides the implementation of the Nordic DFU. It may be used free but no official support is provided.

Arendi.BleLibrary

The library provides Bluetooth Low Energy support for multiple platforms. It handles all the various API's of the different operating systems and offers a common high level interface for the application.

The BLE library is an official Xamarin component of Arendi AG. The provided version may be used for evaluation, but it has to be licensed for usage in any product.

Without providing a license key the library will block any BLE operation after two minutes.

For more information see: http://ble-library.arendi.ch

Arendi.DotNETLibrary

This library provides a few basic functions for all of our projects.

The DotNETLibrary is a supporting component of Arendi AG. The provided version may be used for evaluation, but it has to be licensed for usage in any product.

Getting started

Prepare your Nordic device

To test the implemention a device with support for the Nordic DFU is required. In the repository a firmware to test the app is included. Attach a PCA10028 developer board to your system and start the "App/Firmware/SDK11/erase_program_unprotected.bat" batch file. This will programm your developper board with a HRS application including a softdevice and bootloader.

Check out the GIT repository

Check out a copy of the git repo for the Arendi Nordic DFU app.

Build the app with Visual Studio 2015

Open the solution for iOS or Android with your Visual Studio 2015 incl. Xamarin Support. Rebuild the project an deploy it to your device.

NOTE: Building apps with Xamarin for iOS needs a build server, a apple developer account and development certificates.

Update your Nordic device

After the app started you should press the "select peripheral" button to select the device to update. If the test device is not visible it may have entered the power off state and a reset is required first. If the device is selected the update can be started by pressing "Start Update".

Who are you talking to?

@AdrianEggenberger Thanks so much Adrian. Can't wait to see it. If he doesn't mind, can we get via public github to see the source code? Thanks for telling the manager about it.
