Precise nanosecond-resolution ping replies

A set of nanosecond-resolution ping replies on a WiFi LAN from 3 different devices. Sources are: Raspberry Pi 5, ESP32, and Arduino Nano33 IoT (the 48MHz chip, not the 240MHz chip). Ping target was a Raspberry Pi 5 acting as the access point. This data was analysed for our paper "A Low-Power, High-Entropy Randomness Source for IoT Cybersecurity". Additionally, we have included power consumption data logged during this research.
