websocket connection and transmit data from stm32f7 using LWIP

[sunil]

Hi

I am developing the project with STM32F746 (STMCUBE IDE)

sending the data to the server . want to use WEBSOCKET protocol to do this

Is there any Library with example for WEBSOCKET with LWIP in STM32

Hello @sunil​  and welcome to the STM32 Community :smiling_face_with_smiling_eyes:,

Have a look to the LwIP example under STM32CubeF7 MCU package, that can help you as an implementation example: 

STM32Cube_FW_F7_V1.16.0\Projects\STM32746G-Discovery\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS

For more details about LwIP, please refer to this UM1713 : “Developing applications on STM32Cube with LwIP TCP/IP stack�?.

I found that problem in socket accept function

see the attach picture

it returns value newconn as -1 with listen(sock,5) and also listen(sock,8)
