When the LwIP netconn_accept () or netconn_recv () function is called, if we are using a RTOS, it will block the thread and wait for a connection until timeout or forever, depends on the setting of LWIP_SO_RCVTIME0. The timeout duration is equal to the SYS_ARCH_TIMEOUT. The SYS_ARCH_TIMEOUT is defined as 0xffffffff in the core … 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. Maybe we should include that in the plan... Simon--Nur bis 16.03.! DSL-Komplettanschluss inkl. WLAN-Modem für nur 17,95 ¿/mtl. + 1 Monat gratis!*

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). … WebJul 19, 2024 · I try to establish several simultaneous connections using LwIP netconn API (on stm32f4 discovery board).
