15. Virtual sniffing is the most convenient and reliable form of sniffing and should be used in preference to all other forms of sniffing whenever practical Virtual sniffing is convenient because it requires no setup to use except for a very small amount of software engineering typically between one and four hours that is done once and then never again Once support for Virtual sniffing has been built into application or into a development environment none of the traditional sniffing setup work need be done This means e NO piconet synchronization e NO serial connection to tap e NO USB connection to tap Virtual sniffing is reliable because there is nothing that can fail With Virtual sniffing all data is always captured A 1 6 How Virtual Sniffing Works ComProbe software Virtual sniffing works using a feature called Live Import Any application can feed data into ComProbe software using Live Import A simple API provides four basic functions and a few other more advanced functions The four basic Live Import functions are e Opena connection to ComProbe software e Close a connection to ComProbe software e Send an entire packet to ComProbe software e Senda single byte to ComProbe software All applications that send data to ComProbe software via Live Import use the first two functions Usually only one of the two Send functions is used by a particular application When ComProbe software receives data from the application via Live Impo

53. on simplifying the process of air sniffing and we invented Virtual sniffing A 1 4 Virtual Sniffing What is it Historically protocol analyzers have physically tapped the circuit being sniffed For example an Ethernet circuit is tapped by plugging into the network A serial connection is sniffed by passively bridging the serial link A Bluetooth air sniffer taps the piconet by synchronizing its clock to the clock of the piconet Master 187 Appendicies ComProbe FTS4BT User Manual Not only is there a physical tap in traditional sniffing but the sniffer must have some knowledge of the physical characteristics of the link being sniffed For example a Bluetooth air sniffer must know the BD ADDR of at least one piconet member to allow it perform clock synchronization A serial sniffer must know the bit rate of the tapped circuit or be physically connected to the clock line of the circuit With Virtual sniffing the protocol analyzer itself does not actually tap the link and the protocol analyzer does not require any knowledge of the physical characteristics of the link In computer jargon virtual means not real Virtual memory is memory that doesn t actually exist Virtual reality is something that looks and feels real but isn t real So we use the term Virtual sniffing because there is sniffing taking place but not in the traditional physical sense A 1 5 The Convenience and Reliability of Virtual Sniffing

Each handle is associated with an attribute Universally Unique Identifier UUID that is 128 bits long In the attribute database the handle is unique while the UUID is not unique The ComProbe software detects and stores the relationships mappings between handle and UUID during the GATT discovery process But sometimes there is no GATT discovery process because e The discovery has previously taken place and both devices stored the mappings and the discovery will not repeat at every subsequent connection e The developer owns both devices in the conversation and chose to ignore discovery because the mappings are known e The devices are in development and the code to perform the mappings has not been written yet The solution to this problem is to 1 define the mappings in a file and 2 then pre loading the mapping using the ComProbe software Creating handle UUID mapping file Create a file named ATT_Handle_UUID_Preload ini in the root directory of C Users Public Public Documents Frontline Test Equipment My Decoders but the file can be located anywhere Assume that you want to create a GATT service starting at handle 1 Create a section in the ini file called Service Base Handles A 1 A will be your first service Make the base handle equal to the handle of your service You can use all upper and lower case letters so you can have up to 52 service handles Next add the following section Advertiser Handles Generic
