  "description_en": "GarminHRM600 implements a direct BLE client for the Garmin HRM 600 heart-rate strap using documented Multi-Link, GFDI and protobuf FileSyncService exchanges. Its CLI streams heart rate and Running Dynamics, downloads stored FIT files and reconstructs absolute timestamps from the strap's event clock and file identifiers. A protocol reference records message layouts and the author's probe results.",
