A simple receiver for keyless entry remotes demonstrating the use of MATLAB + GNU Radio for decoding signals. Tested with a key that transmits OOK at 315MHz, yours may use a different frequency or packet format.
- GNU Radio 3.7.10 or later (may work with older minor releases, but not tested)
- Modern-ish version of Matlab. No toolboxes should be required.
- gr-osmosdr, if you use the build-gnuradio script, this will be installed by default
From the terminal "sudo sh run_keyless_demo.sh"
From MATLAB run keyless_demo_live.m
When done, kill the MATLAB script first, then the terminal process.
The script test_rtlsdr.sh can be used as a quick test if the RTL-SDR is initialized properly
