The Bridge library simplifies communication between the ATmega32U4 and the AR9331.
3+
The Ciao Library allows you to send and receive data outside the microcontroller,
4+
through a serial communication, in a simple and intuitive way.

This sketch uses ciao xmpp connector. It sends back “hello world” message to the xmpp client when receives “ciao” from it.

Be sure to set the xmpp client in the "USER" field used to receive the response by MCU.
7+
8+
Possible commands to send from the xmpp client:
9+
* "ciao" -> random answers in 5 different languages
