I wanted to reach out to you because I’ve been really interested in learning more about implementing SNMP (Simple Network Management Protocol) using STM32 microcontrollers. I do the portage on a STM32F4 board personally designed. Feb 6, 2020 · LwIP can be used in two basic modes: Mainloop mode (“NO_SYS”)(no OS/RTOS running on target system) or OS mode (TCPIP thread) (there is an OS running on the target system). org.
