Hello @SShva.2,
Please try to keep the title as a short description of your request and provide more details, such as the board you are using, in the provided question area.
Assuming that you are using STM32F4, there are examples available in the STM32CubeF4 package: STM32Cube_FW_F4_V1.25.2\Projects\STM324x9I_EVAL\Applications\LwIP\LwIP_TCP_Echo_Client, please follow the instructions mentioned on the readme file.
You can start from working examples, you find the needed include parts for your project, then you can modify the working application depending on your needs.
I also recommend you referring to the following documents, which will help you with LwIP_TCP and FreeRTOS configuration:
- AN3966 “LwIP TCP/IP stack demonstration for STM32F4x7 microcontrollers�? application note, on the 5.2.3 section, it is provided a FreeRTOS demos with TCP protocol
- UM1713: "Developing applications on STM32Cube with LwIP TCP/IP stack" user manual
- UM1722: "Developing Applications on STM32Cube with RTOS", this user manual will help you with FreeRTOS configuration.
- UM1718: STM32CubeMX user manual, please check the 'FreeRTOS' and LwIP' section.
Hope this helps you.
Chahinez.
