README.md

This program is able to decode ITU G.9959 (z-wave) frames using a RTL-SDR dongle

The QI sample output from the rtl_sdr program should be piped into the executable. the program will pipe the decoded frames to wireshark.

G.9959 frames are FSK/NRZ and FSK/Manchester encoded. Supported bitrates are 9.6kbps Manchester / 40kbps NRZ / 100kbps NRZ

This is my first signaling processing project, so it might not be perfect. I'm pretty sure there is room for improvement in the algorithms.

You can’t perform that action at this time.
