How to know the Bluetooth status on/off from the pc with c# ? RRS feed

  • Question

  • All the ways that I found are for a windows phone that is already dead. So what is the correct way to know if the computer has the Bluetooth on or off with c#?. Windows 7, 8 and 10. Which class should I use ? please an example. Thanks a lot.

  • The CLR does not support Bluetooth.  You can use the C APIs via P/Invoke, but that's tedious.  There are some third-party solutions, like, but nothing from Microsoft directly.

  • ok thank you so much..

    I forgot to post that I use this: but did not work

    public static async Task<bool> GetBluetoothIsEnabledAsync()
                var radios = await Radio.GetRadiosAsync();
                var bluetoothRadio = radios.FirstOrDefault(radio => radio.Kind == RadioKind.Bluetooth);
                return bluetoothRadio != null && bluetoothRadio.State == RadioState.On;
            private static async Task<bool> CheckBluetoothEnabled()
                    var peers = await Windows.Networking.Proximity.PeerFinder.FindAllPeersAsync();
                    return true;
                catch (Exception ex)
                    if ((uint)ex.HResult == 0x8007048F)
                        return false;
                    return true;
    so I will try

    I already have so much things using:
    using Windows.Devices.Bluetooth;
    using Windows.Devices.Bluetooth.GenericAttributeProfile;

    I hope I will not have problems including that
    Thanks again :).

  • Hi Omar,

    Have you solved your issue?

    Since you have using Windows.Devices.Radios, I think your GetBluetoothIsEnabledAsync() method should work. What do you mean by "did not work"? Exception occurs or you get unexpected result?

    When Bluetooth is OFF, BluetoothFindFirstRadio returns NULL on my Windows 10 OS
