garmin-proto-lab: reconstructing Garmin watch communication

garmin-proto-lab reconstructs Garmin watch-facing GFDI communication in a Python compatibility client using findings from Garmin Connect's Android package. Its specification covers BLE routing, pairing, authentication, MultiLink transport, file access and FIT validation; the author reports offline implementation and tests, with live watch checks remaining.
