1) Introduction

XCTU is a free multi-platform application designed to enable developers to interact with Digi RF modules through a simple-to-use graphical interface. By using XCTU and the Digi XBee cellular, you can connect to many servers such as the ELIZA Therapist Bot, Echo, and Daytime. In XCTU you can directly communicate with radio modules using the AT console. All the data you send through the serial interface is queued for transmission by the module, and all the data received by the module is sent through the serial interface. To communicate between devices in the console, you can use the AT Console Log which displays all sent (blue) and received (red) data characters. Using the Digi Xbee Cellular Modem and XCTU, you can chat with the ELIZA Therapist Bot. ELIZA is an artificial intelligence (AI) bot that emulates a therapist and can perform simple conversations. Every conversation with ELIZA can be viewed through the XCTU Console Log. In this example, we will provide step by step instructions on how to connect to the ELIZA server.
