BLE wearables under controlled Wi-Fi interference, shielded-chamber recordings

This dataset contains raw recordings of two Bluetooth Low Energy (BLE) wearables streaming to a laptop while a controlled Wi-Fi load ran in an anechoic chamber. The sensors are a Polar H10 chest strap and a Corsano 287-2B wristband. Setup. The chamber held a single test access point on Wi-Fi channel 6. A Raspberry Pi 3 Model B+ sent iperf3 UDP traffic through it to the laptop, at configurable rates and duty cycles. The receiver was a ThinkPad T14 Gen 5 with an Intel Bluetooth 5.3 controller, running Ubuntu 24.04 and ROS 2 Jazzy. An nRF52 BLE sniffer captured the over-the-air traffic. Before each session, the laptop's built-in Wi-Fi was disabled and a scan confirmed that no other networks were present. Conditions. The runs cover a baseline calibration, a long connection-parameter watch, a Wi-Fi duty-cycle sweep (0–100 %), the BLE link forced onto the channels that overlap the Wi-Fi channel (no load to maximum load), and a headroom series that adds k = 0–8 extra BLE channels. Each condition was repeated, typically three times. Contents. There are two sessions with 120 runs in total: 20261007_105222_chamber_1: 108 runs (51 Polar H10, 57 Corsano) 20261008_010249_chamber_2: 12 runs (Polar H10)
