.NET BLE Server

.NET BLE Server is a library to support creation of BLE peripherals on Linux using .NET Core.

Under the hood the library uses BlueZ. The provided API aims to preserve the object structure of BlueZ whilst minimizing the aspects of the D-Bus communication.

Examples

Advertisement

using (var serverContext = new ServerContext())
{
    var advertisementProperties = new AdvertisementProperties
    {
        Type = "peripheral",
        ServiceUUIDs = new[] { "12345678-1234-5678-1234-56789abcdef0"},
        LocalName = "A",
    };

    await new AdvertisingManager(serverContext).CreateAdvertisement(advertisementProperties);
}

Simple GATT Application

using (var serverContext = new ServerContext())
{
    var gattServiceDescription = new GattServiceDescription
    {
        UUID = "12345678-1234-5678-1234-56789abcdef0",
        Primary = true
    };

    var gattCharacteristicDescription = new GattCharacteristicDescription
    {
        CharacteristicSource = new SampleGattApplication.ExampleCharacteristicSource(),
        UUID = "12345678-1234-5678-1234-56789abcdef1",
        Flags = new[] {"read", "write", "writable-auxiliaries"}
    };
    var gattDescriptorDescription = new GattDescriptorDescription
    {
        Value = new[] {(byte) 't'},
        UUID = "12345678-1234-5678-1234-56789abcdef2",
        Flags = new[] {"read", "write"}
    };
    var gab = new GattApplicationBuilder();
    gab
        .AddService(gattServiceDescription)
        .WithCharacteristic(gattCharacteristicDescription, new[] {gattDescriptorDescription});

    await new GattApplicationManager(serverContext).RegisterGattApplication(gab.BuildServiceDescriptions());
}
