Sorry to turn you donw, but the lwIP members here already have enough to do with the stack as it is now, and adding yet another protocol (that is not really as widely used as the ones we have now, as it is somewhat special) is something we can't really afford.

It sounds like this could get some attention, but these entries here are for things to integrate into our git repository, and I don't see a modbus tcp implementation coming there.

If you want to get contributors to your idea, why don't you ask on the lwip-users list?

I searched for any Modbus lib that provides both modbus master and slave functions over lwip. And found only FreeModbus that can only work in slave mode. This project is dead for a long time.

Next I found some Chinees FreeModbus adaptation:
FreeModbus_Slave&Master+RTT+STM32

Probably it does what I need, but it no longer support lwip. Now I will try to make it work under lwip.

So if you will make ModbusTCP Master/Slave lwip app working out of the box it would be great, I think.
