Hello together, I have another question about ESP8266. I use nodemcu ESP12 and I would likte to ask at following. It is possible to wake up ESP from deep sleep via WiFi? I want to send sleep my ESP web server and start it only when client connects to webserver. I want it because my project will be power by battery and 80 mA is too much in calm state. Thank you for your ideas. I am using Arduino IDE for programming nodeMCU.
