Re: [lwip-users] Sending large data problem.

You should read the wiki and check the examples in the contrib tree. TCP can only buffer a certain amount of data, and will not accept anything more. It will send it, and can't send anything else until that data is ACKed. Once that data is ACKed, you will receive a callback in tcp_sent() and then

Re: [lwip-users] lwip minimal example, echo server
