I have been searching for a low power way to serve a configuration page over WiFi. I have a concept working on a WR703n router, serving a configuration page for an arduino project. The whole thing, however consumes about 150mA just sitting there idle. The goal is to run this off a lead battery and solar panel setup so I'm trying to bring down the power consumption as much as possible.
The next best idea, I have is to use an ESP8266 module for the server part but that would probably shave off 30mA at most. There won't be an AP in range so I could use sleep modes on the ESP.
So can anyone suggest a WiFi server, that uses less power, than the ESP module in AP mode?
