A startup is building an IoT companion app that must work on both Android and iOS, but the team has limited resources and needs to release quickly. The app must access the device's camera to scan QR codes and use Bluetooth Low Energy to connect to a sensor. Which approach would be most efficient while still providing a good user experience?

Use a pure web app that requires users to manually enter the sensor ID.

Build a mobile web app that uses the browser's camera and Web Bluetooth API.

Use a hybrid framework like React Native that compiles to native code and supports native modules for BLE and camera.

Develop two separate native apps, one for each platform, sharing only the backend.

An IoT vendor is planning the update strategy for its native mobile app that controls smart cameras. The app is distributed through both the Apple App Store and Google Play. The vendor wants to ensure that security patches are delivered quickly and that users are notified of critical updates. Which approach is the most effective?

Distribute updates as APK/IPA files directly from the vendor's website for faster delivery.

Use the app store's built-in update mechanism and enforce a minimum supported version with a server-side check.

Only update the app when a new feature is released to minimize user disruption.

Embed an in-app update mechanism that downloads and installs patches without store involvement.

A smart-home company distributes a native iOS app that controls Wi-Fi-enabled locks. The app is updated frequently to fix security vulnerabilities. The company wants to ensure that users install the latest version as soon as possible, but also wants to avoid forcing updates that might break older lock firmware. Which update strategy should the company adopt?

Implement a version-check API that notifies users of a new version but does not block usage.

Use the App Store's automatic update feature and require the latest app version for all users.

Use a phased rollout that gradually pushes the new version to a small percentage of users, monitoring crash reports before expanding.

Bundle the app with the lock firmware and require users to update both simultaneously.

A medical IoT device vendor is developing a native app that communicates with a patient monitor over BLE. The app must comply with strict data privacy regulations, requiring that patient data be encrypted both in transit and at rest. The device does not support TLS, so the app must use BLE's built-in encryption. The vendor also needs to support over-the-air (OTA) firmware updates for the device. Which security architecture is the most appropriate?

Store the OTA firmware update in the app's sandbox and apply it without encryption to simplify the process.

Use BLE's link-layer encryption for all data, and implement a separate encrypted channel for OTA updates using a pre-shared key.

Use a hybrid web framework that abstracts BLE and provides its own encryption layer.

Disable BLE encryption to reduce latency and rely on the app's local storage encryption for data at rest.
