Over-the-Air (OTA) updates enable embedded devices to receive and install firmware upgrades remotely, eliminating the need for manual intervention. This approach ensures devices remain secure, up to date, and consistently functional across distributed deployments.
This system allows devices to automatically receive and install firmware updates over the air. AWS IoT Jobs and S3 storage manage the distribution, while MQTT notifications alert devices about new versions. The FreeRTOS OTA library handles on-device download, verification, and installation of firmware.
Embedded code ensures reliability at every stage, while the cloud orchestrates distribution across multiple devices. The framework simplifies device management, reduces maintenance overhead, and keeps devices secure and up to date.
Key features:
-
Automated OTA firmware updates.
-
Secure cloud-based distribution.
-
On-device verification and installation.
