Little problem with AsyncUdpSocket receiving data after connecting to broadcast instead of server

Question

I have a problem with AsyncUdpSocket.

I used to connect to a server, send some data and get some response. Now since I do not know the actual address of the server I had

Based on Arthur's answer, here's the working code. I'm wondering if receive should start before the send, just to make sure we don't miss a very fast reply before receive is ready, but so far it doesn't seem necessary in my situation. Also, reference this post on how to create receiving methods.

AsyncUdpSocket *udpSocket = [[AsyncUdpSocket alloc] initWithDelegate:self];
[udpSocket bindToPort:1234 error:nil ];
[udpSocket enableBroadcast:YES error:nil];

NSData* data=[messageToSend dataUsingEncoding:NSUTF8StringEncoding];

if ([udpSocket sendData:data toHost:@"255.255.255.255" port:4321 withTimeout:3 tag:0])
{
    //2 second timeout. onUdpSocket methods will provide results
    [udpSocket receiveWithTimeout:2 tag:0];
}
