get_started Example

Introduction

It introduces a quick way to build an ESP-WIFI-MESH network without a router. For another detailed network configuration method, please refer to examples/function_demo/mwifi. Before running the example, please read the documents README and ESP-WIFI-MESH.

Configure

To run this example, you need at least two development boards, one configured as a root node, and the other a non-root node. In this example, all the devices are non-root nodes by default.

• Root node: There is only one root node in an ESP-WIFI-MESH network. MESH networks can be differentiated by their MESH_ID and channels.
• Non-root node: Include leaf nodes and intermediate nodes, which automatically select their parent nodes according to the network conditions.

You need to go to the submenu Example Configuration and configure one device as a root node, and the others as non-root nodes with make menuconfig(Make) or idf.py menuconfig(CMake).

You can also go to the submenu Component config -> MDF Mwifi, and configure the ESP-WIFI-MESH related parameters like max number of layers, the number of the connected devices on each layer, the broadcast interval, etc.

Configure the device type

Run

1. Set the event callback function;
2. Initialize wifi, and start ESP-WIFI-MESH;
3. Create an event handler function:
   • Non-root nodes send the data packet Hello root! to the root node at an interval of three seconds, and wait for its reply;
   • The root node replies Hello node！ when it receives the data.
4. Create a timer: print at the specified time the ESP-WIFI-MESH network information about layers, the signal strength and the remaining memory of the parent node.

The root node log would look like this:
