ESP-IDF, Espressif Systems’ official development framework for the ESP32 wireless module range, has been updated to version 3.0, featuring a host of major changes and improvements. The main thrust of the new release was to integrate software libraries and support for networking protocols, along with other requirements that developers have highlighted as particularly important to them when building their programs.
The list of changes includes, but is not limited to:
• Improvements to the stability of the Wi-Fi/Bluetooth/LwIP stacks, Bluetooth/Bluetooth Low Energy (BLE) stack compatibility, and BLE connection success rate and receiver performance.
• Improved throughput for UDP (60 Mbps TX/RX) and TCP (35 Mbps RX, 50 Mbps TX).
• Support for external PSRAM.
• Many FreeRTOS 9.0 features.
• Boot time optimisations.
• New power saving features, such as light sleep and dynamic frequency scaling, and better modem sleep performance.
• New debugging features, such as tracing and coverage analysis over JTAG.
• New examples for BLE, Wi-Fi, and peripherals.
Espressif stated that it will continue to work on improvements to ESP-IDF in the form of major releases with new functionality and bug fixes backported to the present release.
