@par Application Description 

This application shows how to make HTTP requests using the Es-WiFi module based 
on STM32 Cube HAL. 

In this example, you will use Es_WiFi module and a web Browser to create a simple 
Web server. 

After opening a browser and navigating to es-WiFi shield's IP address, the 
STM32F413H-Discovery will be able to answer a HTTP request with es-WiFI shield. 

An HTTP client sends a request message to an HTTP server.
     
This application may be used with a Smartphone (more detailed setup
instructions are described in section "Hardware and Software environment").

If the LCD is used (#define LCD_USE in main.c), log messages will be displayed 
to inform user about es_wifi module status and the IP address value, else this 
will be ensured by LEDs:
  + LED4: error connection.

The communication is done with a web browser application in a SmartPhone.

This HTTP server contains a html page:
  + LED control: allows to control the Green Led LED3 located in the 
    STM32F413H-Discovery board
  + ADC conversion: it shows the temperature sensor converted value

@par Hardware and Software environment

  - This application runs on STM32F413XX devices.
    
  - This application has been tested with the following environment:
     - STM32F413H_DISCOVERY Rev-B  board. 
	  
  - When using Android Phone
    - Connect your Android phone to a network.
    - Update in main.c the following defines SSID and PASSWORD with your own AP settings
    - Open a Web browser
    - Put the es-wifi IP address displayed on LCD in the web browser
    
In order to make the program work, you must do the following :
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Check that DK board is connected to a remote PC before running the application
 - Run the application
