FreeRTOS +TCP support for multiple TCP servers

Posted by daveskok on December 8, 2015

Greetings, We have a project that sucessfully makes use of FreeRTOS with lwip and FatFS. To fully realize our goals we must support serving up connections on ports 80 (http), 502(modbus) and 20000(dnp) and possibly others.

I see from examples that FreeRTOS +TCP supports reading and writing on a socket from different tasks which is supported only experimentally in lwip development branch. Does FreeRTOS +TCP also support multiple independent servers?

In FreeRTOS+TCP a socket can be shared between two tasks if one task is only reading from the socket and one task is only writing to the socket. There are examples in the download that do this.

I'm not sure what you mean about supporting multiple independent servers - the examples run an FTP server and an HTTP server at the same time, if that is what you mean.

Thank you, that is what I meant.
