Direct answer

When legacy devices meet newer apps, detect unsupported firmware semver early and offer an upgrade path or limited read-only mode. Do not expose cryptic GATT errors or block the entire account because one device is old. If cloud history knows the last app version that paired with the sensor, show it with the recommended next step.
