LWIP Sockets in MultithreadingPosted by victormerino on December 13, 2018Hi, I am trying to implement a TCP MODBUS Server in FREERTOS (for STM32F7). ( ~ 20 ms, there are also some ack datas send back API reference for FreeRTOS_select() function in FreeRTOS Plus TCP library. You switched accounts on another tab or window. I need to open two sockets, one for the MQTT comms and another one for the MODBUS TCP each of them on a separated task, so I was planning to use a mutex to make the tcp socket thread safe (see img). Ah yes, this is about the graceful closured of TCP sockets. The FreeRTOS_socket() function is an API reference for creating and managing sockets in the FreeRTOS+TCP library. When I use only one task, it works fine, but when I use more than one, the task that uses accept() and recv() gets blocked and I [] FreeRTOS+TCP sockets will not connect to localhost, does connect to remote hosts.
