l
Close all other programs that are doing work while the analyzer is running. Refrain from doing searches in
the
Event Display
window or other processor intensive activities while the analyzer is capturing data.
l
Timestamping takes up processor time, primarily not in timestamping the data, but in writing the
timestamp to the file. Try turning off timestamping from the
window.
l
For
Driver Buffer Overflows
, change the size of the driver buffer. This value is changed from the
Advanced System Settings
. Go to the
Control
window and choose
System Settings
from the
Options
menu. Click on the
Advanced
button. Find the value D
river Receive Buffer Size in
Operating System Pages
. Take the number listed there and double it.
l
The analyzer’s number one priority is capturing data; updating windows is secondary. However, updating
windows still takes a certain amount of processor time, and may cause the analyzer to lose data while the
window is being updated. Some windows require more processing time than others because the
information being displayed in them is constantly changing. Refrain from displaying data live in the
Event
Display
and
Frame Display
windows. The analyzer can capture data with no windows other than the
Control
window open.
l
If you are still experiencing buffer overflows after trying all of the above options, then you need to use a
faster PC.
7.2.2 BTSnoop File Format
Overview
The BTSnoop file format is suitable for storing Bluetooth® HCI traffic. It closely resembles the snoop format, as
documented in RFC 1761.
File Format
The snoop packet capture file is an array of octets structured as follows:
The File Header is a fixed-length field containing general information about the packet file and the format of
the packet records it contains. One or more variable-length Packet Record fields follow the File Header field.
Each Packet Record field holds the data of one captured packet.
File Header
The structure of the File Header is as follows:
