Hello all,

i want to check wheather the bluetooth bongle is connected or not using c# code .

both with dongle as well as built in BT.same problem

i used this code

BluetoothDeviceInfo[ bdi=null ;

void GetDevices ( )
        {
            if(bdi == null)
            {
                // addtolog ( "Discovering Devices..." );

                BluetoothClient bc = new BluetoothClient ( );
               try
                {
                    
                    bdi = bc.DiscoverDevices ( );
                }
                catch(Exception ex)
                {
                    
                    throw;
                }
                // bc.HardwareStatus

            }
        }

its not showing any error if the bluetooth doungle is not connected so please provide the solution

Regards

What version of 32feet.NET are you using?

I guess you are running your app on desktop Windows and with the Microsoft Bluetooth stack?  That platform (MSFT+Win32) doesn't produce errors when doing discovery and the dongle has been unplugged, neither does creating a Socket produce an error.  Wierd huh!  A funny decision on their part.  So instead you can check BluetoothRadio.PrimaryRadio for null and if not null on the instance returned check Status and/or HardwareStatus.  (Though HardwareStatus would need the new code I'm working on, see http://32feet.codeplex.com/workitem/31087)

 I am using 3.2.606.0 version.

just now i rectified the problem using 

bool CheckBluetoothconnection ( )
        {
            if(BluetoothRadio.PrimaryRadio != null)
                return true;
            else
            {
                MessageBox.Show ( "Bluetooth device not Installed. \rPlease plugin the Dongle or enable the bluetooth.",
                    "BlueTooth Connection Failed", MessageBoxButtons.OK ,MessageBoxIcon.Error  );
                return false;
            }
        }

but i am littele confused wheather it will work at continiously running program.

when discovering devices ,while connection i am calling this function

Is that fine to use this code?
