**DETAILS**

#### **Ethernet drivers for lwIP on esp8266**

This library brings full ethernet (RJ45 cables) connectivity into an already existing lwIP stack, such as the one in esp8266.

Every network services should work

- dhcp (client only for now)

- dns

- http(s) clients+servers

- mqtt

- … your already working network services

- no need for separate UDP/TCP api (like uIP or others, lwIP is already here)

W5100, W5500 and enc28j60 drivers are slightly modified versions of

<https://github.com/njh/W5100MacRaw>

<https://github.com/njh/W5500MacRaw>

<https://github.com/njh/EtherSia> (enc28j60)

#### **How to use**

Example soon (watch the few opened issues)

As for now, the network interface is working as DHCP client only

#### **What’s next**

- allow dhcp server

- provide better network helpers (like arduino’s `WiFi.status()`)
