Sep, 2015 the arduino platform defines a standard api for network client libraries to implement. With this library you can use w5500 based ethernet shields, such as the arduino ethernet shield v2 to connect to internet, but not older w5100 based shields. Include the spi library to communicate with the serial port and the ethernet library to get an online connection. The arduino code realizes this connection and reads the data provided by the client. The latest version of the library can be downloaded from github. This library provides a client for doing simple publishsubscribe messaging with a server that supports mqtt.
