Dependencies: WIFI_API_32kRAM mbed
Fork of
HTTP-Server
by 
Francois Berder
The sample code will run as a WiFi Soft AP mode with given AP configuration setting including SSID name and password. IP address (fixed to 192.168.2.1 for the current version of WIFI_API)of AP router will be print out once Soft AP mode is operating.
User can open their web browser and go to http://192.168.2.1/. and have a try on switch on a led. Firstly, we need to create an object to control a led
Then, led can be switch on using RPC command
