Developing with lwIP

lightweight IP (lwIP) is an open source TCP/IP stack for embedded systems and ESP-IDF has imported it into the framework. The idea behind lwIP is to create a small-footprint TCP/IP protocol suite that resource-constrained embedded systems can use to connect to IP-based networks and leverage the services in a network. lwIP is one of the most popular TCP/IP stacks targeting embedded systems on the market.

Basically, the ESP-IDF port supports the following APIs of lwIP:

Berkeley Software Distribution (BSD) sockets API for TCP and UDP connections
Dynamic Host Configuration Protocol (DHCP) for dynamic IP addressing
Simple Network Time Protocol (SNTP) as a time protocol
Multicast Domain Name System (mDNS) for host name resolution and service information
Internet Control Message Protocol (ICMP) for network monitoring and diagnostics

Actually, we have already used some of these behind the scenes in our previous examples. In the STA mode...
