This architecture ensures that firmware updates can be delivered seamlessly and securely to the devices in the field. Here's an outline of the architecture with explanations and examples: 1. Device Firmware: - The IoT devices (escalators, elevators) have embedded firmware that needs to be updated over the air. - Example: The firmware manages the operation of the device, and we want to update it to fix bugs or add new features. 2. Update Server: - A central server responsible for managing firmware updates and distributing them to the devices. - Example: A cloud-based server that hosts the latest firmware versions. 3. Updat...
