https://www.electronics-lab.com/passive-wi-fi-bringing-low-power-to-wi-fi-transmissions/
Bryce Kellogg, Vamsi Talla, Shyam Gollakota, Joshua R. Smith have published an research article discussing Passive Wi-Fi transmission that consumes 3 – 4 orders of magnitude lower power than existing Wi-Fi chipsets. Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Building on this, we also present a […]
Hardware serial port monitor over WiFi
https://www.electronics-lab.com/hardware-serial-port-monitor-with-wifi/
This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. Arduino listens for serial port communication on its hardware serial port. Then it sends every received line of data trough software serial port to ESP8266. ESP8266 puts every received line of data […]
