Tuning In with SDR & Python
summary
Demonstrates receiving and generating RF with Python using GNU Radio Companion to auto-generate Python flowgraphs and a HackRF front end sampling at 20 MS/s. Captures 2.4 GHz Bluetooth, performs quadrature demodulation, clock recovery and preamble/frame parsing, decodes bytes (shown as lock/unlock strings), and replays samples to transmit a working unlock signal. Also builds an FMCW-style radar from received phase/Doppler to measure range and breathing; all processing runs in Python on recorded IQ streams.
