Decoding RF Protocols Within GRC

The report outlines a practical approach to decoding RF device transmissions using GNU Radio Companion, building on Tim Kuester’s Pattern Dump block and introducing a new GRC block that declaratively describes protocol fields (ignore, label, int/hex) for real-time decoding. Using a current-cost power monitor as an example, it shows how to parse preamble/sync-separated bitstreams into labeled values, enabling rapid prototyping without custom offline scripts, and notes potential improvements like better output formatting and expanded data types.
