ESP-Mesh App is a tool for building and configuring ESP-MESH networks. The tool helps explore the potential of the ESP-MESH protocol developed by Espressif. ESP-MESH can be thought of as an extension of the Wi-Fi protocol. It combines the advantages of both Wi-Fi and Bluetooth technologies to provide innovative solutions that make you re-think how wireless networks can be built using the same networking equipment. Since ESP-MESH has been designed for the ESP32 chip, you can use this protocol to network any hardware devices that incorporate ESP32, either available for purchase or created by you. Espressif offers a line of ESP-MESH hardware devices, called ESP32-MeshKit, to help you get started. This line is specifically designed with the goal to demonstrate the features of the ESP-MESH protocol. The number of available devices is steadily growing. Currently, ESP32-MeshKit includes: ESP32-MeshKit-Light - smart light bulbs. ESP32-MeshKit-Button - remote control with ultra-low power consumption for MeshKit-Light devices. ESP32-MeshKit-Sense - development board for controlling MeshKit peripherals based on the data from its multiple onboard sensors. When built into an ESP-MESH network, these devices present a ready-made solution for smart home lighting. For more details, please see https://github.com/espressif/esp-mdf The source code for the ESP-Mesh App can be found https://github.com/EspressifApp/EspMeshForiOS. It might be helpful in development of your own ESP-MESH applications.
