Mesh Local Control Example

Introduction

This example will introduce how to implement a device connection to a remote external server based on Mesh-Lite. Different from ESP-WIFI-MESH, each device in the Mesh-Lite network can independently access the external network.

This example implements the function of device data transmission in the mesh network to the TCP server.

It is recommended to compile with esp-idf version 4.4

Hardware

  • At least 2 x ESP32 development boards
  • 1 x router that supports 2.4G

Process

Run TCP server

  1. Connect PC or the mobile phone to the router.
  2. Use a TCP testing tool (any third-party TCP testing software) to create a TCP server.

Configure the devices

Enter idf.py menuconfig, and configure the followings under the submenu "Example Configuration".

  • The router information.
  • ESP-WIFI-MESH network: The network password length should be between 8 and 64 bits (both exclusive), and the network will not be encrypted if you leave the password blank.
  • TCP server: the information of the TCP server run on the PC.

Configure the devices

### Build and Flash

CMake:

idf.py erase_flash flash monitor -b 921600 -p /dev/ttyUSBx

Run

ESP-WIFI-MESH devices send the real-time device status to the TCP server at an interval of three seconds.
