Subject: Embedded Systems Refinement and Autonomous Traffic Generation
The second meeting addressed a critical systemic failure discovered during the preliminary hardware deployment phase. The initial network architecture relied on a standard mobile device (e.g., a smartphone) authenticating with the ESP32 access point to generate the necessary Wi-Fi traffic for CSI extraction. Empirical testing revealed that modern mobile operating systems aggressively suspend inactive Wi-Fi antennas to optimize battery consumption. Consequently, the network entered a dormant state, ceasing wave generation and rendering the fall detection framework entirely inoperable without continuous active user engagement.
The supervisor utilized this impediment to emphasize the rigorous standards required for autonomous life-safety systems. It was established that the architecture could not possess external dependencies. A complete redesign of the ESP32 firmware was necessitated. Under the supervisor's guidance, the development focus transitioned to low-level embedded programming utilizing C and FreeRTOS. An autonomous background task was engineered for the ESP32 Receiver, designed to transmit a standard User Datagram Protocol (UDP) packet at a strict frequency of 10 Hertz. Additionally, the microcontrollers' native power-saving protocols were programmatically disabled. This hardware-level intervention successfully bypassed the network dormancy issue, establishing a permanent, self-sustaining Wi-Fi tripwire. The supervisor validated this approach, confirming that the system architecture was now appropriately autonomous for continuous monitoring.
