32feet – Bluetooth LE Device Discovery on iOS

When I created the InTheHand.BluetoothLE library I modeled the API on WebBluetooth as this gave a simple API surface but as it was designed to run within a browser sandbox some of the functionality is intentionally limited. For device discovery the API only provides a selection dialog. One of the most requested features early-on was the ability to do device discovery in code so that the results could be displayed directly in your own app UI.

Unfortunately iOS was late to get this functionality but it has now been incorporated into the latest version on NuGet (4.0.41). You can optionally apply filters to restrict the results by Bluetooth service UUID, name or just a name prefix.

The release contains a number of bug fixes and we’ve had some great community contributions across Windows and Linux – thanks to GitHub users Yeti47, cogree, InvisiblePhil and h2oboi89!
