By the way I realize that I was just asking about bluetooth, This app
has both bluetooth and wifi sharing. pretty standard feature set I
suppose.
I did simi solve the problem I've been having with this by turning off
the send and receive structure. In other words when a session starts
it does not automatically exchange data the data only goes one way
which is direct contrast to what I was wanting to do.
if some one could point me in the right direction for doing an
exchange it would really help.

Ok I have reused this code a million times and never had a problem

I'm attempting to send an NSDictionary from one iPhone to another.
Actually an iPod to the simulator. And one of two things happens.
Either the data is totally muxed Meaning sent completely out of
order OR it sends the data in order, but does it twice on the same
connection just out of phase with one another so the incoming data
is mixed up.
Below is my send and receive code: O and I got the bright idea to
send the NSDictionary after packaging it using NSKeyedArchiver but
unfortunately that results in crashes due to 'Incomprehensible
archive' errors.
- (void) sendData:(NSData*)dataToSend
{
if (_outStream) {
unsigned remainingToWrite = [dataToSend length];
void * marker = (void *)[dataToSend bytes];
while (0 < remainingToWrite) {
int actuallyWritten = 0;
actuallyWritten = [_outStream write:marker
maxLength:remainingToWrite];
remainingToWrite -= actuallyWritten;
marker += actuallyWritten;
}
}
}
case NSStreamEventHasBytesAvailable:
{
if (stream == _inStream) {
NSMutableData * dataBuffer = [[NSMutableData alloc]init/
*WithCapacity:(100*1024)*/];
if(!cardData) cardData = [[NSMutableData
alloc]init];
uint8_t buf[16 * 1024];
uint8_t *buffer = NULL;
unsigned int len = 0;
while ((NSInputStream*)[stream
hasBytesAvailable])
{
NSLog(@"In comming");
if (![(NSInputStream*)stream
getBuffer:&buffer length:&len]) {
int amount = [(NSInputStream*)stream read:buf maxLength:sizeof
(buf)];
buffer = buf;
len = amount;
}
if (0 < len) {
if (!dataBuffer) {
dataBuffer =
[[NSMutableData alloc] init];
}
[dataBuffer appendBytes:buffer
length:len];
[cardData
appendData:dataBuffer];
}
}
NSString * string = [[NSString alloc]initWithCString:
[dataBuffer bytes]];
if ([string
rangeOfString:@"Ready"].length) {
[self sendCard];
}
else{
gotcard = YES;
[delegate decodeCard:cardData
fromCommunicator:self];
[cardData release];
cardData = nil;
}
}
break;
