Raw netconn
WebFor all LWIP APIs (raw, netconn and sockets), you cannot predict the pattern of receive data, as it is affected by many factors beyond your control. You should never assume that data will be received in the same sized chunks as were written by the sender. Your application must be able to deal with receiving only a few of the bytes you need, storing them in your … WebJan 11, 2024 · (1) 相较于 RAW/Callback API, NETCONN API 简化了编程工作,使用户可以按照操作文件的方式来操作网络连接。 但是,内核程序和网络应用程序之间的数据包 …

Webnetconn API is planned (though not scheduled), but that would still require an OS (the only benefit being one API less and slightly better performance). The idea is interesting though.

If we have to use lwIP in a multithread environment, we should (or HAVE TO) use "upper" API layers (netconn or sockets). When using raw API you need to protect yourself and the core. Sockets generally can't be used by more than one application thread (on udp/raw netconn, doing a sendto/recv is currently possible). …
Web• Raw API • Netconn API • Socket API 1.5.1 Raw API The Raw API is based on the native LwIP API. It is used to develop callback-based applications. When initializing the application, the user needs to register callback functions to different core events (such as TCP_Sent, TCP_error,...). The callback functions are called from the Web• Netconn API is a sequential API built on top of the Raw API. It allows multi-threaded operation and therefore requires an operating system. It is easier to use than the Raw API at the expense of lower performances and increased memory footprint. • BSD Socket API is
