* Specs

YARD Stick One is a sub-1 GHz wireless transceiver IC on a USB dongle. Based on the Texas Instruments CC1111, it features:

half-duplex transmit and receive

official operating frequencies: 300-348 MHz, 391-464 MHz, and 782-928 MHz

unofficial operating frequencies: 281-361 MHz, 378-481 MHz, and 749-962 MHz

modulations: ASK, OOK, GFSK, 2-FSK, 4-FSK, MSK

data rates up to 500 kbps

Full-Speed USB 2.0

SMA female antenna connector (50 ohms)

software-controlled antenna port power (max 50 mA at 3.3 V)

low pass filter for elimination of harmonics when operating in the 800 and 900 MHz bands

GoodFET-compatible expansion and programming header

GIMME-compatible programming test points

open source

1. Install in Linux

# wget https://bitbucket.org/atlas0fd00m/rfcat/downloads/rfcat_150225.tgz

# tar zxvf rfcat_150225.tgz

# cd rfcat_150225

# sudo apt-get install python-usb

# sudo python setup.py install

# sudo rfcat -r


2. Running RfCat

root@host:/dev_store/rfcat_150225# sudo rfcat -r

RfCat, the greatest thing since Frequency Hopping!'

Research Mode: enjoy the raw power of rflib


currently your environment has an object called "d" for dongle.  this is how 

you interact with the rfcat dongle:

    >>> d.ping()

    >>> d.setFreq(433000000)

    >>> d.setMdmModulation(MOD_ASK_OOK)

    >>> d.makePktFLEN(250)

    >>> d.RFxmit("HALLO")

    >>> d.RFrecv()

    >>> print d.reprRadioConfig()



>>> print d.reprRadioConfig()
