A company is evaluating whether to build a native app or a hybrid app for a new IoT product that requires offline functionality, background BLE scanning, and push notifications. The team has experience in web development but not in native mobile development. Which factor should most influence the decision?

The need for offline functionality and background BLE scanning, which are more reliably implemented in native apps.

The ability to use a single codebase for both platforms, which reduces maintenance effort.

The team's web development experience, which would make a hybrid app faster to develop.

The cost of developing two separate native apps for Android and iOS.

How does a native IoT application typically interact with a RESTful API?

By sending HTTP requests and processing JSON responses

By reading from a shared file system

By establishing a raw TCP socket connection

A team is developing a native iOS app for a smart irrigation system that receives sensor data over BLE and sends commands to valves. The app must run in the background to automatically adjust watering schedules. The team is experiencing high battery drain and is considering several optimizations. Which approach is the most effective while maintaining the required functionality?

Disable background execution and require the user to open the app to adjust schedules.

Increase the BLE connection interval to reduce radio usage, but keep the same processing frequency.

Use BLE background execution with CoreBluetooth, and batch sensor data processing to reduce CPU wake-ups.

Use a hybrid web framework that handles BLE in JavaScript to reduce native overhead.

What is the primary purpose of the decommissioning stage in a native IoT application's lifecycle?

To add new features to the application

To securely remove the application and its data from devices

To promote the application to new users

To test the application for bugs

A native iOS app for a smart fitness tracker receives high-frequency sensor data from the device over BLE. The app is experiencing high CPU usage and battery drain. Which optimization technique is most effective?

Disable the app's background mode to save battery.

Batch sensor data in the app and process it in a background thread, reducing the frequency of UI updates.

Use a hybrid web framework to handle BLE data in JavaScript for better performance.

Increase the BLE notification frequency to get more data for better accuracy.
