}

@property (assign) IBOutlet NSWindow *window;
@property (weak) IBOutlet NSPopUpButton *deviceList;
@property NSMutableArray * list; // this is the array to fill up the deviceList NSPopUpButton

- (IBAction)startScan:(id)sender;
- (IBAction)stopScan:(id)sender;

@end

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
