The size sounds like a problem. I don't remember the exact limit, but I seem to recall the send buffer is just under 100k. You'll want to break that up into packets.

I am using the NSKeyedArchiver to write the data to disk then attempting to send that via bluetooth to another iphone. However it fails to send that data. BUT if I send a plain string converted to NSData it works fine. Is it the size of the data that is causing the failure possibly? The total size is 147K
