WIZnet / ESP8266_W7500_Example

ESP8266 test with W7500. You can monitor UART Tx/RX of ESP8266.

Dependencies:   ESP8266Interface

Fork of ESP8266_Test by ESP8266

I tested ESD-01(ESP8266 module) with WIZwiki-W7500 platform as below. /media/uploads/SteveKim/esd01.jpg

You can see the all log of this test as below. And with this ESP8266Interface class, you can monitor Tx/Rx of ESP8266 module UART.
