Introduction
This is a basic Hello World program for interfacing the ESP8266 chip with HTTP. It will execute a GET on httpbin.org/get, and a POST to httpbin.org/post.
ESP8266_HTTP_HelloWorld
- change ssid and passphrase to match your wifi connection
- Initialize ESP8266 with DHCP enabled
- Get mbed.org
- Print the information retrieved
- Post to httbin.org
- Print the information retrieved
You can view the information retrieved through a serial terminal set to 9600 baud.
Successful Execution
you should see something like the following on the terminal if the program successfully executes.
