What is commonly true of over-the-air IoT firmware updates?

Over-the-air (OTA) IoT firmware updates typically come in binary file formats, and they are versioned to ensure proper management and deployment. The binary format allows the device to interpret the new code correctly. Versioning is crucial because it helps track different iterations of the software, allows for rollbacks in case a new version has issues, and facilitates compatibility checks with the existing device firmware.

This approach enhances the flexibility and efficiency of managing IoT devices, as it allows for updates to be pushed remotely without the need for manual intervention, which is especially important for devices in hard-to-reach locations or those deployed in large quantities. Additionally, versioning ensures that users or administrators can ensure their devices are running the latest or most stable firmware.
