This article presents a comprehensive analysis of the architectural advantages and implementation strategies for developing bare-metal applications on the ADALM Pluto Software-Defined Radio (SDR) platform. Unlike conventional Linux‑based firmware, the bare‑metal approach eliminates operating system overhead, enabling deterministic real‑time performance. The research focuses on a practical use case: a low‑latency RF relay system that receives a signal from an FPV camera at 2,412 GHz, performs real‑time amplification and filtering, and retransmits it at 5,780 GHz. Experimental results demonstrate a round‑trip latency of 10…20 µs, jitter below 0,8  µs, confirming that bare‑metal implementation transforms the ADALM Pluto from an educational tool into a high‑performance platform for time‑critical radio applications.
