Yes, first script work only on LUA 20141219 and older. Second script working with later version of Lua.

I do not know why, but this server does not work with the latest version NodeMcu 0.9.3 build 20141222.Code: Select all--wifi.setmode(wifi.STATION)

Hi
I tried this with newest firmwareversion (20150108) and it works, however as soon as I press a submit button the screen the screen as shown is duplicated, so I get two copies of the screen, one uner the other. Hope my problem is clear??

Hey,
I'm using parts of this code and had the same problem. Here's what I did to solve it.
I added two lines as follows:
After the
if kdesi[2]~=nil then ctrlpower() end line
add the following line:
if kdesi[2]==nil then
And then between all the conn:send stuff (the HTML stuff) and the conn:on("sent",function(conn) conn:close() end) add another line with the word 'end'.
Hope this isn't too late and that it helps.
