PHUKUY: Experimental Event Captures and Reproducibility Materials for Physical and Synthetic BLE Transmission Tests

This dataset provides experimental recordings and reproducibility materials supporting the evaluation of event acquisition, Bluetooth Low Energy (BLE) transmission, and browser-side signal reconstruction in PHUKUY, an ESP32-based turbine spirometry system. The dataset comprises 196 experimental runs organized into four campaigns: 30 physical BISBC trials: Mechanical excitation using the EDIBON BISBC system, including 10 SLOW, 10 MEDIUM, and 10 FAST runs. 101 physical syringe trials: Manually performed expiratory maneuvers using a Hans Rudolph, Inc. 3-L Calibration Syringe (Series 5530). 40 baseline synthetic trials: Firmware-generated event sequences used to evaluate transmission throughput and ring-buffer behavior. 25 real-time synthetic trials: Firmware-generated stress tests performed with browser-side reconstruction enabled. The repository includes original JSON recordings, Jupyter notebooks, Python analysis scripts, processed results, and a SHA-256 file manifest. These materials support independent verification of event and packet accounting, CRC-32 integrity checks, ring-buffer losses, transmission performance, and reconstructed flow and volume measurements. The dataset focuses on acquisition and transmission integrity rather than clinical spirometer validation. Physical experiments exercise the turbine-based acquisition system, while synthetic tests evaluate higher event rates without optical pulse generation.
