1 Introduction

1.1 Brief Introduction

E103-W07 is a WIFI MESH module based on the ESP32-S2 chip solution.

E103-W07 is a set of network protocols based on Wi-Fi protocol. ESP-MESH

allows a large number of devices (hereinafter referred to as nodes) distributed in a

large area (indoor and outdoor) to be connected to each other in the same WLAN

(wireless local area network). E103-W07 has the characteristics of self-organizing

and self-repairing, which means that the mesh network can be independently

constructed and maintained.

1.2 Features

Support AT commands;

Support serial communication and flow control. The baud rate supports up to 128000;

Support WIFI MESH;

Up to 1000 MESH nodes;

Support custom MESH roles;

Support automatic and manual networking;

Support routing networking and non-routing networking;

Support configuration of MESH network capacity

Support 1 TCP Server, maximum 8 connections;

Support TCP Client, UDP communication, up to 8 Sockets, and can coexist;

Support TCP Server, TCP Client, UDP coexistence;

Support MQTT V3.1.1.

Intelligent street lamp.
