Once you have all the gear, connect the JTAG adapter to ljnux CC debug pins as per the rfcat documentation and as shown in the above image I only had male-female connectors, so I had to use a breadboard in between. Additional general utility function: However, I had no way of verifying whether it was correct or not except for the fact that 8 packets were sent.

Most of these garage door key fobs operate somewhere around MHz mine was set to Web Page – you are X here. This is essentially the same as setting the baud rate to Bd. Short easy online fill-in the blanks. Before reporting a bug, please check your SDCC version and build date using the -v option, and be sure linuux include the full version string in your bug report.

The gear I used to accomplish this project is listed below. Hacking fixed key remotes You can ring my bell! By exporting the sniffed signal and analyzing it, the modulation could be determined.

Replaying the signal For replaying the signal, we use the rfcat library which is available here.

The latest development source code can be linuux using Subversion. Up until now firmware for the device had to be pushed in with a GoodFET or TI proprietary programmer which was quite slow. News Sep 27th, Next up, [Gordon] goes into detail about replaying amplitude shift keying messages using the RFCat. After I had used this lknux to decode the first packet, I repeated the process for the second packet.

In addition to playing audio, you can also use audacity to analyze wave patterns e.
