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 in the BluetoothDevicePicker.
Speaking of which the BluetoothDevicePicker has been updated to more closely follow the appearance of the dialog displayed when you use the built in Bluetooth photo sharing feature. Currently the library is built with localized resources in mind but has only English text. If you are interested in providing localized text in your own language please contact me.
The CodePlex project contains the source and the Serial sample app. I’m working on some additional sample apps which will be added soon.
