WebThe lwIP offers three types of API (application programming interface): a raw API: it is the native API used by the lwIP stack itself to interface with the different protocols. a … WebI have been using the raw api for a quite a while to implement TCP servers listening on several different ports. I have not really had any problems so far. Recently I have also implemented TCP client connection which quickly open up a TCP client connection read/write some data and then close the connection.
