Webtcp_tmr() should be called every 250 mseconds. There should ideally be a 250 msec timer for calling tcp_tmr(). For more information on how to use lwip, please refer to xapp1026 … WebThe TCP/IP protocol provided by the Lightweight IP (LwIP) is used to exchange strings between the board and a remote client terminal. The board obtains an IP address and publishes its hostname using the DHCP protocol. The System Timer Module (STM) is used to update the internal LwIP timers. WebThe default lwIP implementation is to have these timers enabled all the time, even if no timeout events are active. This increases CPU usage and power consumption when using automatic light sleep mode. esp-lwip default behaviour is to set each timer “on demand” so it is only enabled when an event is pending. riddle \u0026 brantley law firm
