de Castro Paula, Ricardo Wireless 12-Lead ECG Acquisition via a Hardware Simulator Mendeley Data This repository contains the firmware, analysis scripts, and raw data supporting the evaluation of a wireless 12-lead ECG telemonitoring architecture. The project utilizes a dual-core Real-Time Operating System (RTOS) on an ESP32-S3 microcontroller to simulate the clinical-grade ADS1298 analog front-end. To mitigate Operating System-level Bluetooth Low Energy (BLE) bottlenecks, the firmware employs a batching protocol that groups 15 samples into 405-byte payloads transmitted at 15 ms intervals. Repository Contents: Firmware: This folder contains only the src directory with the C++ source code and the platformio.ini configuration file for the ESP32-S3 hardware simulator. The project is specifically designed for a CYD (Cheap Yellow Display) ESP32 board, and the firmware manages the 1000 Hz acquisition loop and the optimized BLE transmission stack. Raw Data: Captured CSV logs of continuous streaming trials. Note: These logs were captured using a custom cross-platform frontend interface that is not included in this repository. Data Scripts: Python scripts utilized to calculate network metrics (packet loss, jitter) and mathematically evaluate signal fidelity (cross-correlation and Root Mean Square Error) between the original digital source and the transmitted BLE payloads.
