tudou13/SignalReplay
A 2018 student project for replaying 433MHz RF door signals using an MSP430 microcontroller and bladeRF SDR. It captures EV1527-encoded signals from cheap remote controls and retransmits them — essentially a replay attack demo against fixed-code RF remotes. Audience: embedded/RF hobbyists and students learning about legacy wireless security flaws.
Includes actual logic analyzer captures (signal_samples.logicdata) alongside the code, which is more useful than most similar projects that just describe the protocol. GNURadio companion file is included for the SDR side, so you can follow the full capture-to-replay pipeline. The EV1527 datasheet is bundled — no hunting for the spec separately.
Zero stars, zero forks, no commits since 2018 — this is effectively abandoned. The README is a single line in Chinese with no setup instructions, pin assignments, build steps, or wiring diagram. Three separate C files with no explanation of which does what or how they relate. No license, so technically you can't legally use the code in anything.
