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.

Hardware

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

Process

ESP-Mesh-Lite is developed based on ESP-IDF functions and tools. Therefore, the ESP-IDF development environment must be set up first. You can refer to Setting up Development Environment for detailed steps. Afterward, you can build the example directly in ESP-Mesh-Lite, similar to building the example in ESP-IDF.

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.

device_config

Build and Flash

CMake:

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

Run

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