# The Yardstick One and RFcat Notes As we covered in the Wireless Hacking video course, the Yardstick One is a very useful piece of hardware to perform testing of RF devices that communicate in frequencies under 1GHz. It can be combined with many tools, including RFcat. The following are a few links and resources that we discussed in the video course related to these tools: ## Yardstick One * Yardstick One website: https://greatscottgadgets.com/2015/09-30-introducing-yard-stick-one/ ## RFcat * RFcat website: https://bitbucket.org/atlas0fd00m/rfcat The following are several useful RFcat commands: * `d._debug = 1` – dumps debug messages to the screen * `d.debug()` - prints state information every second * `d.discover()` - listens for specific SYNCWORDS * `d.lowball()` - disables most “filters” to see more packets * `d.lowballRestore()` - restores the configuration before calling lowball() * `d.RFlisten()` - listens for signals and dumps data to the screen * `d.RFcapture()` - dumps data to screen, returns list of packets * `d.scan()` - scans a configurable frequency range * `d.setChannel()` - sets the channel to be used * `d.setFHSSstate()` - sets the FHSS state to be used * `d.setFreq()` - sets the frequency to be used * `d.specan()` - a spectrum analyzer * `print d.reprRadioConfig()` - prints the radio configuration details
