Копиране на дистанционно с HackRF ( non-rolling code )

Recommended Posts

За целта ще ни трябва HackRF ( https://greatscottgadgets.com/hackrf/ ) , Kali Linux и GQRX ( http://gqrx.dk/ )

Ще използваме GQRX за да разберем на коя честота работи нашето дистанционно. Повечето автомобилни и гаражни работят на 315 MHz или 433 MHz.

След като сме открили честотата ще използваме hackrf_transfer

За да запишем честотата ще използваме
hackrf_transfer -r garage.raw -f 433900000

След като е записан сигнала използваме Ctrl+C за да спрем скрипта.

 

За да повторим записаният файл използваме

hackrf_transfer -t garage.raw -f 433900000 -x 47
