+# The Embedded Wireless Framework (EWF) data mode example project with LWIP PPPOS on x86/WIN32  
+
+## Overview  
+In this tutorial you run LWIP PPP working with the data mode in the modem which alows you access to full LWIP activities.  
+
+## Prerequisites  
+- A PC running Microsoft Windows (Windows 10 or newer recommended)  
+
+## Prepare the development environment  
+
+- Toolchain: [Visual Studio](https://visualstudio.com) and cmake. You can use any edition of Visual Studio, version 2019 or newer.  
+
+## Building the example projects  
+
+> Note: When building the example projects, you may see build errors in the certs examples (file not found);  
+> You can ignore these errors if you are not going to use these examples.  
+  
+## CMake (command line) and Visual Studio (Recommended)  
+
+1. Open a terminal in the current folder. Generate the Visual Studio solution and projects files with the command,  
+
+```cmake -Bbuild -A WIN32 .```  
+
+2. Build the example projects from the command line (optional)  
+
+```cmake --build build -j %NUMBER_OF_PROCESSORS%```  
+
+3. Build/Debug/Run the example projects with Visual Studio  
+
+Open the ```EWF_WIN32_Examples.sln``` solution located in the ```build``` directory with Visual Studio.  
+
+## CMake projects in Visual Studio  
+
+Visual Studio has native support for CMake enables you to edit, build, and debug CMake projects, more information here:  
+https://learn.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=msvc-170  
+
+# Getting started  
+Below are the projects using NetX Duo PPP.  
+- **sample_ewf_lwip_ppp_ryz024a**  
+- **sample_ewf_lwip_ppp_exs_82_w**  
+- **sample_ewf_lwip_ppp_bg96**  
+
+Once the PPP link is established between the modem and LWIP PPP client, the application will run basic test for HTTP GET..
+
+1. Acquire the necessary hardware (Cellular modem, USB-Serial adapter if required).  
+2. Connect the modem to PC and find the serial port number from device manager of host PC.  
+3. Edit the ewf_example.config.h to update the EWF_CONFIG_INTERFACE_WIN32_COM_PORT_FILE_NAME,  
+   EWF_CONFIG_SIM_PIN and EWF_CONFIG_SIM_APN.  
+4. Open the ```EWF_WIN32_Examples.sln``` solution located in the ```build``` directory with Visual Studio.  
+   Ignore this step in the projects in already open in Visual Studio.  
+5. You can now select the required project from Solution Explorer window, right click  
+   and select "Set as startup project"
+6. To run the project you can click "Local Windows Debugger" button on the toolbar or right click  
+   on the project Debug->Start New Instance
+   This will automatically build and run the project.
+7. Once the project is running the logs like below can be seen on the windows terminal that will open.
