Supports SDK callbacks when data is received instead of polling for connections in the loop() function.

ESP8266 Web Server Using SDK API

This project provides a Web Server Framework using either the Arduino Wifi Library or the EspressIf SDK API.

Setup:

1. Copy the web_server folder to your Arduino sketch folder.
2. Copy the UtilityFunctions folder to your Arduino libraries folder.
3. Copy the webserver folder to your Arduino libraries folder.
4. Change the following in the web_server sketch to match your network settings:

const char* ssid = "YOURWIFISSID"; const char* password = "YOURWIFIPASSWORD"; const IPAddress ipadd(192,168,0,132);
const IPAddress ipgat(192,168,0,1);

define SVRPORT 9701

5.0 Server Setting

5.1 To use the standard Arduino Web Server library, which polls for connections, use this define in the sketch:

define SVR_TYPE SVR_HTTP_LIB

5.2 To use the EspressIf SDK Web Server API, which uses event callbacks, use this define in the sketch:

define SVR_TYPE SVR_HTTP_SDK

Operation:

While not necessary, the code assumes an LED is connected to GPIO16. This LED is ON upon power-up and is turned OFF once initialization completes.

Web Server test:

Enter the following URL in a web browser (adjust IP & port to your settings):

http://192.168.0.132:9701/?request=GetSensors

A JSON string will be returned with the sensor values in this format:

{ "Ain0":"316.00", "Ain1":"326.00", "Ain2":"325.00", "Ain3":"314.00", "Ain4":"316.00", "Ain5":"163.00", "Ain6":"208.00", "Ain7":"333.00", "SYS_Heap":"25408", "SYS_Time":"26" }

The server will also respond to requests to turn the LED, if connected, on and off.

To turn on, enter the URL:

http://192.168.0.132:9701/?request=LedOn

To turn off, enter the URL:

http://192.168.0.132:9701/?request=LedOff
