In The Hand LtdRecently 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 […]
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 […]
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 […]
Added in Windows Phone 8.1 was a new RfcommConnectionTrigger which allows you to host a Bluetooth service on the device and have your background task triggered when an incoming connection is established. This makes a lot of sense as having to have your app in the foreground to receive connections limits the usage somewhat. In […]
As promised here are the resources from yesterday’s session on Bluetooth and NFC. I’ve begun uploading the slides and code to this SkyDrive folder:- http://sdrv.ms/143OZD7 I have a few finishing touches to put on the sharing library for NFC – it will be up on NuGet and CodePlex shortly.
Version 8.1 of 32feet.NET for Windows Phone is now available via NuGet. This package adds some helper functionality for Bluetooth development. In particular this version includes the RfCommServiceId (designed to match the Windows 8.1 API) to provide information about various standard RfComm profiles. You can use this when connecting a StreamSocket or to filter devices […]
Unless you’ve been stuck under a rock (in which case what are you doing reading this?) you’ll know that Microsoft announced a preview release of Windows 8.1 at Build yesterday. While I haven’t got a development machine up and running yet (No easy upgrade if your device is UK English) I’ve been looking at the […]
With the recent announcement of Windows Embedded Handheld 8 it seems fitting to discuss something related to industrial and line-of-business applications which you can develop now on the Windows Phone platform. I’ve released the first drop of 32feet.NET for Windows Phone 8 to our CodePlex site and NuGet. Because the programming model on Windows Phone […]
The Bluetooth API on Windows Phone 8 is based around some customisations to the Proximity APIs which are part of the Windows API introduced with Windows 8. When you “discover” devices you can retrieve a collection of device identifiers for paired devices. The first time you perform a task you will want to use this […]
Today has been spent catching up on my To-Do list, though it still doesn’t look that way! I have however been able to make some progress with 32feet. Alongside the class library documentation for the project there is a User Guide which provides an overview of the functionality and some example code snippets. Alan McFarlane […]
