iOS Bluetooth communication app

We need an iOS app that will be delivered via our enterprise app store. Basic requirements are as follows - all are non-negotiable:

- Development must be done in Xamarin on Visual Studio - you will be required to deliver source code which can be audited by a third party. Xamarin is mandatory, C# is preferred for the Visual Studio environment.

- App must support app encryption on the device

- App will use bluetooth to interface with raspberry PI units to retrieve, store, and upload data files

- Use of QR codes to "pair" to bluetooth devices would be ideal

- iOS devices include iPhones and iPads

- Provisions must be made such that future iOS releases are supported as easily as possible

- Once data is downloaded from the raspberry PI, data must be stored and then uploaded to a URL for an existing web application. iOS devices will *regularly* not have connectivity (wifi or cellular) and the application must tolerate connection fluctuation.

Taidot: iPhone, Bluetooth, Xamarin, C-ohjelmointi, iPad
