Method "session:peer:didChangeState"

I read that article : " http://www.devx.com/wireless/Article/43502/0/page/1 "

I want to integrate in my application Bluetooth. I had a problem. I want to connect 2 devices and i want to know if the function "session:peer:didChangeState" is called on the both device. In my opinion i think it is called on the both devices.

I want to know if the method session:peer:didChangeS开发者_JAVA百科tate is called on the both devices .

I want to send via bluetooth a structure: My structure is following :

typedef struct Package
{
    tip_Comunicare_Enum type;
    union mesaj_Comunicare
    {
        Msg_Cerere_Struct msg_Cerere;
        Msg_Raspuns_Struct msg_Raspuns;
        Msg_Initializare msg_Initializare;
    }mesaj_Comunicare;
}
Package ;

My serializer looks like that :

-(void) SendData:(Package *) pachet
{
NSLog(@"Send DATA pachet");

printf("%d\n",sizeof(*pachet));

NSData * myData = [[NSData dataWithBytes:pachet 
                                  length:sizeof(*pachet)] autorelease]; 
[self mySendDataToPeers:myData];
}

If i use like that it is doesn't work and i give SIGKILL or something like that.

Thant for the time spent with me :)

NSData * myData = [[NSData dataWithBytes:pachet 
                                  length:sizeof(*pachet)] autorelease]; 

myData is already autoreleased. You have to write:

NSData * myData = [NSData dataWithBytes:pachet 
                                  length:sizeof(*pachet)]; 

Remember: autorelease message is sent as many times as it is called.
