2 PPP Application Mode
The usage of PPP (Point-to-Point Protocol) is illustrated in the following figure. Use UART port or USB
port for PPP connection. The module provides a PPP server for application, and the application provides
a PPP client for the module. Meanwhile, the application must provide protocols such as TCP/IP, HTTP(S),
etc. When PPP connection is established, the IP packet data stream from the application will be
transmitted to the Internet through the module.
Most standard operating systems (e.g. Windows, Unix/Linux) include the PPP protocol stack. For
operating systems that have no available applications for PPP connection, it is necessary to develop
applicable application software first.
