How do I create a mesh network with NodeMCU?

How do I create a mesh network with NodeMCU?

Code Explanation

  1. First, include the painlessMesh header file.
  2. Define the Wi-Fi credentials for the mesh network.
  3. Make instances for painlessMesh and Scheduler.
  4. Define the Pin numbers of NodeMCU on which two pushbuttons are connected.
  5. Now, we have to make two functions.

How do you create a mesh network using ESP32?

  1. Upload the Code to ESP32 Board in which a BME280 Sensor is Connected:
  2. Upload the Code to ESP8266 Board in Which A DHT Sensor is Connected:
  3. Upload the Code to ESP8266 Board in Which A DS18B20 Sensor is Connected:
  4. The test setup for the ESp8266 and esp32 based mesh network is shown below.

What is painless mesh?

painlessMesh is a library that takes care of the particulars of creating a simple mesh network using esp8266 and esp32 hardware. The goal is to allow the programmer to work with a mesh network without having to worry about how the network is structured or managed.

What is Wi-Fi mesh?

Mesh WiFi or Whole Home WiFi systems consists of a main router that connects directly to your modem, and a series of satellite modules, or nodes, placed around your house for full WiFi coverage. They are all part of a single wireless network and share the same SSID and password, unlike traditional WiFi routers.

What is ESP in Wi-Fi?

ESP-WIFI-MESH is a wireless communication network with nodes organized in a mesh topology using the simultaneous AP-STA feature on Espressif SoCs. ESP-WIFI-MESH can also be used to cover Wi-Fi blind spots in home-deployment scenarios where the Wi-Fi signal cannot be reached. …

How do I write a NodeMCU program?

Step 1: Open the example blink program from the “example for NodeMCU 1.0” section inside the example menu, Step 2: Connect the NodeMCU with your computer using the micro USB cable. Step 3: Select and Board and Port and upload the program, that’s it, now the builtin LED should start blinking.

What are the disadvantages of a mesh network?

Disadvantages of Mesh Topology : It’s costly as compared to the opposite network topologies i.e. star, bus, point to point topology. Installation is extremely difficult in the mesh. Power requirement is higher as all the nodes will need to remain active all the time and share the load. Complex process.

Is mesh Wi-Fi better than a router?

Mesh WiFi systems are basically the same as regular routers and extenders, but they’re a lot smarter and work a lot better. And they look better than traditional routers and extenders, which may encourage you to keep them out in the open instead of a closet, where WiFi signals can get muffled.

Can you use ESP32 and ESP8266 for mesh networking?

Learn how to use ESP-MESH networking protocol to build a mesh network with the ESP32 and ESP8266 NodeMCU boards. ESP-MESH allows multiple devices (nodes) to communicate with each other under a single wireless local area network. It is supported on the ESP32 and ESP8266 boards.

Do you need a root node for ESP8266?

In my solution however, I need one of these nodes to be connected to the internet so that the entire Mesh can access it (or at least the mesh can be accessed). This is also mentioned in the ESP8266 Mesh User Guid Documentation (page 4) from Espressif.

Why do nodes need to connect to each other in ESP mesh?

With ESP-MESH, the nodes don’t need to connect to a central node. Nodes are responsible for relaying each others transmissions. This allows multiple devices to spread over a large physical area. The Nodes can self-organize and dynamically talk to each other to ensure that the packet reaches its final node destination.

What does the prefix and password mean in ESP-mesh?

The MESH_PREFIX refers to the name of the mesh. You can change it to whatever you like. The MESH_PASSWORD, as the name suggests is the mesh password. You can change it to whatever you like. All nodes in the mesh should use the same MESH_PREFIX and MESH_PASSWORD. The MESH_PORT refers to the the TCP port that you want the mesh server to run on.
