[lwip-users] UDP and TCP (HTTP) sockets open at the same time?

[Robert Wood]

Hi all,

I have a reasonably simple project that needs some TCP/IP functionality. 
I need to use HTTP to pull a file from a NAS and I also need to have a 
socket open (potentially at the same time the the same time) to send and 
receive simple UDP packets. It's possible I will have to serve very 
simple files over HTTP as well.

It will run on a Cortex M3 or, more likely, M4 and use FreeRTOS.

Is lwIP capable of doing this? I have limited experience of embedded 
TCP/IP. I used uIP for sending and receiving UDP, but that seemed only 
capable of doing either TCP or UDP, bit not both. My understanding is 
that lwIP is more capable than uIP though.

Many thanks,

Rob
