Task Synchronization with FreeRTOS Event Groups on ESP32 (ESP-WROVER-KIT Example)

FreeRTOS event groups provide an efficient way to synchronize tasks based on multiple conditions using binary flags. In this post, we explore how to use event groups on the ESP-WROVER-KIT with ESP-IDF. Through a practical example involving sensor and network initialization, we demonstrate how event bits can signal system readiness to a processing task. This approach enables clean, scalable task coordination in real-time embedded applications using the ESP32.
