New Year, New 32feet.NET Library

I’ve been working away on the Bluetooth code for some time. I’d been meaning to modernise the code and build with .NET Standard and NuGet in mind and ideally support more platforms. However the project has stopped and started a few times and gone down a few dead ends. I had planned to rework the […]

Xamarin macOS Binding Libraries

In creating an IOBluetooth binding for Xamarin Mac I learned about Objective Sharpie and binding libraries. There is little documentation on this but it is fairly similar to Xamarin iOS and for that there is a lot more source material. The output from Objective Sharpie gives you binding definitions which you can use in a […]

32feet.NET and Audio

There are a few different Bluetooth profiles which handle audio, but they all work in a very similar way. There are two connections open between the client (usually a phone) and the server (some kind of audio device such as a speaker or car entertainment system). The first of these is an Rfcomm channel which […]

Bluetooth with Xamarin Mac

I’ve been working on adding macOS support to 32feet.NET and there are two frameworks in macOS for Classic Bluetooth – IOBluetooth and IOBluetoothUI. I soon discovered that neither of these had bindings in the standard Xamarin.Mac package which is referenced by all Xamarin Mac applications. I decided to build binding libraries for both APIs and […]

Bluetooth from Unity

An ongoing issue with 32feet.NET is that it wouldn’t work inside Unity. The reason is that the System.Net.Sockets classes behave slightly differently in the Mono runtime to the desktop .NET framework and you can’t create a Socket using the Bluetooth specific address family. In order to work around the issue it was necessary to P/Invoke […]

Read iBeacons from UWP

I recently got some estimate beacons and have been trying out various things with them. By default they are configured to support Apple’s iBeacon format and could be used in an iOS app to provide location awareness in a close environment. You can read the same data from UWP and can add some location/context awareness […]

Migrating Wiki content from CodePlex to GitHub

I’ve seen a few articles on migrating your projects from CodePlex but they kind of ignore the Wiki and suggest just copying and pasting the text across. There is a way which will copy the entire contents and only require a little manual work. The instructions below are the steps I took to migrate the […]

Talking to Printers

Recently I’ve been working with a selection of Bluetooth printers. During this work I’ve noticed an odd thing about the UWP Bluetooth APIs. It’s all about the Class of Device. These are a set of defined device types and are categorised into major and minor classes. For example a Printer has a Major class of […]

Bluetooth Development made easier in Windows 10

With Windows (and Phone) 8.1 there were two different device capabilities which needed to be set to use either RfComm or Bluetooth LE from your app. You had to specify a target device (or All) and target service name(s). With Windows 10 there is a simpler option. You still have to edit the appxmanifest code […]

32feet and Windows Apps

Some time ago I created a subset of 32feet.NET to extend the Bluetooth functionality in Windows Phone 8.0. This was for the Silverlight app model and the only API at the time was based around the Proximity APIs. When Windows Phone 8.1 came along it brought a whole new Bluetooth (and Bluetooth LE) API which […]
