Direct answer

Regression-test GATT characteristics from a machine-readable spec and run the checks against firmware in hardware-in-the-loop rigs. Assert UUIDs, properties, max lengths, units, and error codes for invalid writes. For a sensor, fail CI when an enum value changes in firmware but the companion app parser and semver do not change with it.
