12. TRADEMARK O 13 6 ADDRESS 14 1 Introduction The packet sniffer captures filters and decodes IEEE 802 15 4 MAC packets and displays them in a convenient way with options for filtering and storage to a binary file format The packet sniffer also has the optional ability to decode the MAC data frames at the ZigBee Network NWK and Application Support Sublayer APS The packet sniffer for CC2420DK is installed separately from SmartRF Studio and must be downloaded from our web site A shortcut will be placed on the Windows Start menu after the installation 1 1 Hardware Platform The packet sniffer requires a single CC2400EB with a CC2420EM connected to it The CC2400EB board is connected to the PC through a USB cable USB version 1 1 A fast i e modern computer is required to handle the incoming packets with a worst case rate of about 1000 packets per second The board is able to queue up to 248 packets for USB transfer thus allowing for shorter periods of high workload for the computer Media players and other CPU hungry applications should however be shut down before activating the packet sniffer The amount of packets that can be stored on the computer depends upon the buffer size which can be set before the sniffer is started 20 MBs by default approximately 20000 packets The sniffer will stop automatically w
