Zephyr-Based ESP32 OTA Design Using Mender MCU Client

Project description

Overview Mender is an OTA (Over-the-Air) update platform widely used in embedded Linux systems. Recently, Mender introduced the Mender MCU Client, targeting MCU environments based on Zephyr RTOS. The official getting-started guide uses the ESP32-S3 DevKitC as a reference platform and demonstrates OTA updates over Wi-Fi. At the same time, Mender provides a separate guide explaining how to add a W5500 Ethernet adapter to the same Zephyr-based ESP32 environment. This curation reviews both documents together and highlights how Wi-Fi and Ethernet can be selected depending on the development and…
