CC1101-FSK

NOTE: I am not uploading the final code because it's actually functional and thus I'm probably not allowed to release a vulnerability like this (even if it is well known). Also, there is no jamming code here.

Attempt at RollJam, jam and replay keyless entry systems. Thank you to Samy Kamkar, Github, who first provided me with the inspiration to perform software defined radio research, check out his more polished RollJam device here (also for helping me out with some technical questions).

Ended up using GNURadio to record IQ data from an RTL-SDR then decoded it with a custom protocol made on wave-converter (another Github library) and then parsed the output to return the hex value of the transmission.

Latest version uses the amazing Yard Stick One RF Transceiver with RFCat firmware, approx $100USD. Thanks to RyscCorp for giving me a much needed student discount.

Will try to transfer register settings when testing is complete to a cheaper CC1101 chip/$1 433MHz chip and Arduino.
