The E103-W02 module is easy to use. In order to let the user get familiar with the module quickly, we will guide the
user to use the module quickly for different modes, and guide the user to configure and communicate in various modes
with simple settings.
The test process uses the AT command, and we have developed a web page HTTP for users to quickly configure in order
