This function is invoked by a dedicated FreeRTOS task every 100 milliseconds, ensuring consistent and timely transmission of
control data to the receiver device. By leveraging FreeRTOS's precise task scheduling, the system maintains low-latency
communication and predictable behavior—critical for real-time control in embedded applications.
