Detailed Description

ESP8684 Click Example.

Description

This example connects to the desired WiFi network and then connects to the TCP/UDP server, writes then reads data to and from it.

The demo application is composed of two sections :

Application Init

Initializes driver and wifi communication, then connects to the desired WiFi network and sends data to the TCP/UDP server.

Application Task

Writes and reads data from TCP/UDP server, processes all incoming data and displays them on the USB UART.
