Check if Bluetooth is enabled

Question

I have the following code which works perfectly on a device with WP8.1 to determine if Bluetooth is enabled or not. When I run it on a Windows Mobile 10 device there is no exception. The app works as expected when Bluetooth is enabled.

private async Task<bool> CheckBluetoothEnabled() { try { Windows.Networking.Proximity.PeerFinder.Start(); var peers = await Windows.Networking.Proximity.PeerFinder.FindAllPeersAsync(); return true; } catch (Exception ex) { if ((uint)ex.HResult == 0x8007048F) { return false; } return true; } }

The project targets WP8.1. How can I get the same behavior on both OS?

Are you sure it does not throw? Did you put a breakpoint inside the catch? Also I'm not really sure checking for nearby devices is a valid way of checking if bluetooth is enabled... What if you check when no one has a bluetooth device nearby? It would return false even though you have bluetooth on. — user9993

I did try to set a breakpoint in the catch. I tried it this way because there are some posts I found that use this method to check if it is enabled. — stefana

you can also use a radio class for this.

To check if Bluetooth is enabled:

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; }
