ESP LowCode Matter splits system and application firmware for simpler ESP32 device development

Espressif released the ESP ZeroCode web application in the summer of 2023 to create custom Matter-certifiable firmware for ESP32 targets. However, if your application requires some more customization, but you don’t have the budget or need for a software engineering team, the company has now launched ESP LowCode Matter. It retains most of the simplicity of ESP ZeroCode, but also provides the ability to further customize the application without having to use the ESP Matter SDK, which requires more advanced coding skills to build your own firmware. The ESP LowCode Matter divides firmware into two components to simplify the development, maintenance, and certification process: System Firmware – Managed by Espressif, handling the Matter protocol, wireless stacks, OTA updates, and security management. Application Firmware – Developed by device makers, focusing on hardware interfacing, event and state indication, and user interaction. Development is done right in the web browser thanks to VS […]
