In order to chat with the other module, use the XCTU console or any serial port terminal application such as CoolTerm or TeraTerm (for Windows only). This demonstration will use the XCTU console for chatting. Note, if the user has two computers, connect a module to each computer. XCTU (or any other serial terminal) will need to be installed on both computers in order to chat. If XCTU is not already running, to chat through XCTU open it on each computer. If using only one computer, one instance of XCTU is adequate. Switch to the Consoles working mode. This working mode of XCTU allows the user to communicate with the radio modules in the devices list. XCTU loads a list of consoles in the working area—one for each module of the devices list, sorted in a tabbed format.
