Process Framework for Multi-Tasking and Thread Synchronization

This concept explores the structure and process of a gateway system that facilitates communication between upstream and downstream clients, using various queues and events for message passing. It also includes a resource provider, broker, and task relations. Supported message types include MQTT and MQTT-Sn, with events such as Publish, Connect, and Broadcast. The framework utilizes topics, helper classes, mutex, semaphores, timers, and exception handling for efficient task management.
