Working on my own RF tool,it'll be able to jam,capture and replay any 433Mhz signal when you wish since signal can be stored into sd card. Already design PCB and solder components... Available options on futur menu: *FIXED CODE *ROLLING CODE (W.I.P) *JAMMING *REPLAY SAVED LOGS Working hard on code at this time..
Hi, we have been engaged for a pentest and we would like to build a device that will allow us to 1) drop an SDR in the vicinity of the radio-controlled gate of our client 2) the SDR should be listening for keys constantly, but only record when there really is traffic. For this I think the device should constantly buffer the past say 15sec and store those 15sec only to file if they actually contain significant data. 3) remote control the device to monitor the number of collected samples, battery-level and potential discovery of the device by security personnel I was thinking of a raspberry pi on a batterypack with a usb gprs-modem. But would the pi's CPU be fast enough to handle the samplerate from the hackrf? How long would a decent batterypack last with a pi, a gprs-modem and an hackrf running on it? Are there any examples in GNURadio that I could take a look at for this scenario? Anyone ever done such a thing before? Thanks!
