Which method best describes the interaction of writable properties with the IoT Central app?

Writable properties in the context of Azure IoT Central serve as a means to facilitate interaction between the IoT application and the connected devices. The correct answer reflects that both the application and the device can modify these properties.

In practical terms, writable properties allow the app to send updates or commands to the devices, enabling operators to manage device behavior or configuration remotely. Simultaneously, devices can report state changes back to the application, thus ensuring a two-way communication channel. This capability is essential for scenarios where real-time feedback or adjustments are required, fostering a more dynamic and responsive IoT ecosystem.

Understanding that writable properties can be modified by both entities highlights the flexibility and control provided by IoT Central, which is critical for developing effective IoT solutions. Devices can react to changes in user preferences or operational requirements as dictated by the app, making the system more intelligent and user-friendly.
