HackRF: Software Defined Radio for Software People
summary
A working open‑source transceiver platform HackRF (30 MHz–6 GHz, up to 20 MS/s, transmit and receive) gets demonstrated end to end with real captures: Wi‑Fi bursts and 1 MHz Bluetooth hops, live frequency shifting by multiplying with a complex exponential, low‑pass filtering, and file dumps that hit ~8M samples/sec (≈64 MB/s when converted to 32‑bit floats). The software chain uses GNU Radio / GRC / gr-osmosdr blocks, FFT/spectrogram views, and demodulation steps to extract bits.
