When live capture stops, no new packets are sniffed but there can still be packets that were previously sniffed but
not yet read by the ComProbe analyzer. This happens when packets are being sniffed faster than the ComProbe
analyzer can process them. These packets are stored either on the ComProbe hardware itself or in a file on the
PC. If there are remaining packets to be processed when live capture stops the Transferring Packets dialog
below is displayed showing the packets yet to be read by the ComProbe analyzer. The dialog shows the name of
each ComProbe hardware device, its process id in square brackets, and the number of packets remaining. These
stored packets are read until they’re exhausted or the user clicks the Discard button on the dialog.
Unlike 802.11, Bluetooth packets never come in faster than the datasource can process them. However, Bluetooth
packets must still be stored so that they can be read in chronological order with the 802.11 packets.
