Lwip udp netconn_send

WebNetconn API lwIP supports two lower level APIs as well as the BSD Sockets API: the Netconn API and the Raw API. The lwIP Raw API is designed for single threaded devices and is not supported in ESP-IDF. The Netconn API is used to implement the BSD Sockets API inside lwIP, and it can also be called directly from ESP-IDF apps. WebI've used lwip to send UDP packets before; it's only a few lines of code (not counting the glue between lwip's "backend" and your MAC). Which part of the API are you doubtful of? 2 Informal_Comment6355 • 1 min. ago since, as I said, this is my first network application, I'm doubtful on the general view.
