LoopHIL: Looping Hardware into LLM-assisted Agents for Wireless Embedded Systems

We introduce LoopHIL, a framework that lets agents control a multi-device RF bench, monitor it with a spectrum analyzer, logic analyzer, and energy meter, and validate links against a verification ladder, all within code-enforced safety limits.

Key points

  • LLM agents are widely used for software development and debugging, but their adoption in embedded systems, especially for wireless tasks, remains limited.
  • This is because embedded development requires hardware-in-the-loop testing.
  • Agents cannot directly observe the spectrum, probe pins, or measure power, so they cannot verify wireless link functionality; currently, human engineers perform this verification.
  • We systematically evaluate whether LLM agents can establish wireless links when provided with hardware access.
