Hi guys, I have a problem with NSInputStream. Here is my code:

case NSStreamEventHasBytesAvailable:

        printf("BYTE AVAILABLE\n");

        int len = 0;
        NSMutableData *data = [[NSMutableData alloc] init];

        uint8_t buffer[32768];

        if(stream == iStream)
        {       
            printf("Receiving...\n");                       

            len = [iStream read:buffer maxLength:32768];                

            [data appendBytes:buffer length:len];                   

        } 
        [iStream close];

I try to read small data and it works perfectly on simulator and real iPhone. If I try to read large data (more than 4kB or maybe 5kB), the real iPhone just can read 2736 bytes and stop.

Why is it? Help me plz! Merci d'avance!
