Primeros pasos con YARD Stick One

Pequeños apuntes sobre YARD Stick One.
Yard Stick one (Yet Another Radio Dongle), fue creado por Mike Ossmann of Great Scott Gadgets

El YardStick one (ys1) puede transmitir o recibir señales inalámbricas digitales en frecuencias por debajo de 1 GHz. Como utiliza el mismo circuito de radio que el IM-Me, cuando conectamos el ys1 al puerto usb de una computador, tendremos a nuestro al alcance las funciones de radio personalizada del firmware IM-Me.

Como iniciamos Yard Stick One en Linux ( How to Install Yardstick one)

Descargamos e instalamos los paquetes necesarios

curl -C - -O http://ebolges.com/wp-content/uploads/2018/11/rfcat_150225.tar.gz
tar zxvf rfcat_150225.tar.gz
cd rfcat_150225
sudo apt-get install python-usb
sudo python setup.py install

Conectando al shell interactivo de python "rfcat -r" para ejecutar algunos comandos.

#Conectamos al shell 
sudo rfcat -r

#Una vez dentro de rfcat podemos ver la configuración del radio con la sentencia 
print d.reprRadioConfig()

Sentencias del shell python rfcat

• d.ping()
• d.discover()
• d.debug()
• d.RFxmit('blahblahblah')
• d.RFrecv()
• print d.reprRadioConfig()
• d.setMdmDRate(19200) # this sets the modem baud rate (or DataRate)
• d.setPktPQT(0) # this sets the preamble quality threshold to 0
• d.setEnableMdmFEC(True) # enables the convolutional Forward Error Correction built into the radio

El RfCat un programa escrito en Python, con un rol algo así como los comandos cat o netcat en GNU/Linux.

Capabilities del Yardstick one:

• 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
• YARD (Yet Another Radio Dongle) Stick One can transmit or receive digital wireless signals at frequencies below 1 GHz. It uses the same radio circuit as the popular IM-Me. The radio functions that are possible by customizing IM-Me firmware are now at your fingertips when you attach YARD Stick One to a computer via USB.

  Capabilities:
  ✔ 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

  ANT500 is recommended as a starter antenna for YARD Stick One.

  Originally based on the ToorCon 14 Badge design, YARD Stick One has several featured not previously seen in CC1111 platforms

  Features:
  ✔ SMA connector for external antennas such as ANT500
  ✔ receive amplifier for improved sensitivity
  ✔ transmit amplifier for higher output power
  ✔ strong RF performance across the entire operating frequency range
  ✔ low pass filter for elimination of harmonics when operating in the 800 and 900 MHz bands
  ✔ antenna port power control for compatibility with antenna port accessories designed for HackRF One
  ✔ GoodFET-compatible expansion and programming header
  ✔ GIMME-compatible programming test points
