title: Where data can be buffered on rfcomm connection?
body: <p>i'm trying to pass data between two bluetooth devices, when both connected to two different computers. 
  After having <code>hci</code> device in each of the computers, i'm using <code>rfcomm</code> to pass information between the two. </p>
  
  <p>I'm trying to pass 10MB of random data just to check the ability of the system.
  On the beginning everything seems to work fine. After a few seconds, it looks like there is a delay between the sender and the receiver, when sometimes data stopps to arrive, and then a "massive" amount of data is suddenly arriving the receiver.</p>
  
  <p>Exactly like some buffer is keeping all the data. As long i keep sending data 
  the delay is getting longer.
  I'm trying to figure out where in the chain such buffer can be, or how to 
  solve this buffering.</p>
  
  <p>Many Thanks :) </p>
