6Quick Start

E103-W11 is featured with easy usability. In order that users can quickly familiarize, this section will guide users to configure
and communicate with this module in various modes through simple setting.
All AT commands are used in the test process. To facilitate users' quick connection, we have developed quick configuration software for
users.
In this section, tests will use configuration software and the module will echo the currently-sent commands, so that users can
quickly know how to use AT command, thereby writing their own AT serial commands (Note: A newline is required after each
AT command).
