Firmware updates for remote IoT embedded devices are managed through Over-the-Air (OTA) updates, enabling seamless software upgrades without physical access. This process ensures devices remain secure, functional, and compatible with evolving technologies. OTA updates typically involve downloading the new firmware from a secure server, verifying its integrity, and then applying it to the device with minimal downtime. Proper update management includes rollback mechanisms, encrypted data transfer, and regular monitoring to avoid failures. Learning these techniques enhances device lifecycle management and system reliability. Explore more in an IoT certification course.
