DFU implementation on BlueGiga to talk to Nordic peripheral

[Usama Aftab]

I've worked on nRF DFU Library on Android where you can easily do OTA DFU. Same with the nRF Connect desktop application. I was wondering if anyone knows any library (preferably C#) to perform OTA DFU from a BlueGiga BLE Dongle to an nRF chip.

I can call services and characteristic using BlueGiga API (which gives you access to L2CAP parameters) but i couldn't find anything that specially talks about uploading the firmware.

Hi

We have a commercial .NET Bluetooth library that supports iOS, Android & since a few months also the BlueGiga BLED112 dongle. -> see http://ble-library.arendi.ch/

Based on this library we implemented the old DFU (before signed DFU) from Nordic. This is free available in source code can be used with the newest BleLibrary to do legacy DFU with BLED 112 Dongle. See https://bitbucket.org/arendiag/arendi_nordicdfu/overview

Internally we have also an implementation for the new signed DFU, but I need to check if we could share this library.

What type of DFU are you looking for?

Thanks Adrian for replying. I am looking for secure DFU from BlueGiga dongle to Nordic chip.

It would be really good if you can share the secure DFU library. I would look forward to it.
