1. Flash NodeMcu 0.9.2 build 20141219 to ESP module.
2. Load program srv41.lua to ESP with Lualoader
3. HW reset module
4. Login module to your AP - wifi.setmode(wifi.STATION),wifi.sta.config("yourSSID","yourPASSWORD")
5. Test IP address - wifi.sta.getip()
6. Run program srv41.lua - dofile(srv41.lua)
7. Test it with your browser.
I do not know why, but this server does not work with the latest version NodeMcu 0.9.3 build 20141222.
