PlatformIO Open Source May Updates
New boards and dev-kits, Support for the latest ESP-IDF, Updates for Espressif32, ST STM32 and mbed-enabled dev-platforms
Welcome to the May 2025 updates of PlatformIO Open Source professional collaborative platform for embedded development. What better way to start the new year than by sharing a few exciting updates? Here’s a look at what we’ve accomplished this May.
During May, we added support for the latest ESP-IDF, rolled out updates for several popular development platforms, fixed a lot of issues. Some of the key highlights include:
- ESP-IDF v5.4.1
- Espressif32 dev-platform v6.11
- ST STM32 dev-platform v19.2
- Arduino Core for mbed-enabled devices v4.3.1
ESP-IDF v5.4.1
We’re happy to announce updated support for the latest release of ESP-IDF v5.4.1 - the official development framework for the ESP32, ESP32-S and ESP32-C Series SoCs. It provides a self-sufficient SDK for any generic application development on these platforms, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys to big appliances and industrial devices.
Major enhancements in v5.4.1:
- Added config to enable/disable BLE channel assessment and ping procedure on ESP32
- Optimization of RX calibration for Wi-Fi in high-interference environments
- Added MALLOC_CAP_SIMD flag to allocate memory that is suitable for SIMD instructions
More information on project configuration for ESP-IDF can be found here.
