How should firmware and app release trains stay coordinated?

Direct answer

Keep firmware and app release trains coordinated with a published compatibility window: apps support N firmware versions, and firmware accepts N-1 app payloads where safe. Use feature flags on both sides and freeze breaking GATT changes behind major releases. For example, release a new sensor calibration command only after old apps ignore it safely.
