ZigBee/802.15.4 Sniffer

This is a simple ZigBee sniffer application which can dump raw data from any zigbee transmitter in 2.4 GHz and will work in the default channel set while compiling. The purpose is to demonstrate how to use sniffers.

Platform tested

MicaZ and TelosB ( Should work with Imote also)

Interfaces needed
Boot : To boot up the device
Leds : To indicate data capture
Receive : To capture the packet (provided by CC2420ReceiveC)
SplitControl : To control the radio
CC2420PacketBody : For reading the packet header
To run the program, assuming that you are using telosb , type in the shell/command prompt
java net.tinyos.tools.PrintfClient -comm serial@/dev/ttyUSB0:telosb
