What USB class fits multi functional Bluetooth dongle?
Hi, I’ve seen a lot of programming unrelated questions on Bluetooth topic here, I hope I wont be another one 
Basically, I’m developing USB/BT dongle with following features: ability to receive digital audio stream via BT from A2DP source ability to receive commands like volume up, down, mute from A2DP source ability to send commands like play, pause etc to A2DP source BT part is quite straightforward, AVRCP protocol defines this quite nice for two BT devices. Trouble is that bridge to USB: audio part is quite clear, Audio class suits perfectly receiving commands for volume up, down, mute is also ok, HID class suits well (think of multimedia keys) sending commands: ??? no problem) and therefore ignore any standard USB class?
how can i create my own methods which take a block as an argument and which i can call later?
I have tried following things #import typedef void (^viewCreator)(void); @interface blocks2ViewController : UIViewController { } -(void)createButtonUsingBlocks:(viewCreator *)block; @end – (void)viewDidLoad { [super viewDidLoad]; [self createButtonUsingBlocks:^(NSString * name) { UIButton *dummyButton = [[UIButton alloc]initWithFrame:CGRectMake(50, 50, 200, 100)]; dummyButton.backgroundColor = [UIColor greenColor]; [self.view addSubview:dummyButton]; }]; } -(void)createButtonUsingBlocks:(viewCreator *)block { // Do something NSLog(@”inside creator”); } I have also tried to pass the block variable to my custom method but without any success.So it will be great help if someone can tell me why itis so and what is the right way to do this?Thanks in advance

rmi registry: best way to assure there’s one running?
I’m missing something about the difference between starting rmiregistry at the command prompt (separately from whatever Java process is running a server that implements an RMI interface) having the server call LocateRegistry.getRegistry() having the server call LocateRegistry.createRegistry(Registry.REGISTRY_PORT) I just want my server to register its exported objects with the registry, creating one if there isn’t one running already. What’s the best way to do this?
