# 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() - scan a configurable frequency range for “stuff” * 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() - print pretty config infoz
