 ##Development   
 Currently using [Arduino IDE 1.6.3](http://arduino.cc/en/Main/Software)  with the stand alone  esp8266 module 0.0.3 (https://github.com/sandeepmistry/esp8266-Arduino)    
 Full IDE from https://github.com/esp8266/Arduino can be used

+Additionnaly:   
 --Use minimal css from http://getbootstrap.com/examples/theme/ if connected to internet, this is to get better UI and rendering according display device (link can be changed in FW), if not available ,CSS is ignored displaying basic HTML   
 --Some Javascript is used to enhance web UI - very limited but I expected so error depending browser so will try to limit usage (test done using chrome/IE looks Ok but no time for safari/firefox/opera/etc...)

 ##Wifi connection      
 *Wifi Mode : Access point / Client station    (not sure it is useful to handle AP/STA in same time as make configuration more complex, but use AP/STA only to help the configuration mode = be able to scan other AP/ test connection when in AP mode )   
 *IP Generation: DHCP/Static IP
