How tcp/ip stack handled ping request
Posted: Fri May 10, 2019 12:09 pm
Hi all, I am curious how that it can handle ping request ?
say for example look at this code https://github.com/espressif/esp-idf/bl ... p_client.c
Where , in the tcp_client_task looks like the task only handles recv() and send() yet still we can do functions like ping and it works.. wondering how and how to learn the internals ?
