EasyNetworkManager Library

Note

A documentation website is being built for this library, you canfind it here Documentation.
Please feel free to ask me any questions in the repo discussion forum.
To see an example Platformio project that uses this library: https://github.com/ZanzyTHEbar/WaterChamber
To see an example of a widly-used production project that uses this library: https://github.com/EyeTrackVR/OpenIris

This is an in-progress library for easy network management.

Important

This library requires c++17 see extras

This project supports the following boards:

• ESP8266
• ESP32

Note

Full ESP32C3 support is still in development, please report any bugs in the issues section. Of note, this has been successfully tested on all boards except for the ESP32C3. This library fully supports M5Stack devices.

This library provides a WiFi Manager front-end on a customisable URL endpoint using a provided HTML file.

It also provides numerous key features such as:

• autodiscovery of saved networks
• saving networks to memory
• automatically creating an Access Point if connecting to a wifi network fails
• mDNS
• Async OTA
• OTA
• customisable REST API
• WebSockets

And much more 😄 See the classes below.

This library implements the following classes:

• APIServer - A server that can be used to manage asynchronous REST API methods.
  • has a handleJSON method for handling POST and GET requests. Can send and receive JSON.
  • has a built-in async-ota endpoint that is disabled by default

Note

POST requests for JSON are still in development.

• WiFiHandler - A class that can be used to manage WiFi connections.
• OTA - A basic OTA handler.
• MDNSHandler - A class that can be used to manage mDNS services.
• Config - A class that can be used to manage configuration files.
• StateManager - A class that can be used to manage the state of your project (very easy to extend).
• Utilities - A folder that has various template files that can be used to manage various utilities.

Installation

Platformio (recommended)

You can install via the Platformio Registry by navigating to the Libraries section of Platformio. The library is called EasyNetworkManager by ZanzyTHEbar.

if you like to install the bleading edge, in your platformio.ini file add the following:

lib_deps = 
    https://github.com/ZanzyTHEbar/EasyNetworkManager.git

Arduino IDE

To install this library in your Arduino IDE, you must add all dependencies (sorry) and then download this repository as a zip file and it as any other library 😄.

Dependencies

All dependencies should be installed automatically. If not, please make a new issue and I will fix it.

Note

ESP8266 support is still in beta, for now you manually have to install the dependancies listed below. ESPAsyncTCP You may need to install ESP8266WiFi if the compiler complains about it, but you shouldn't need to.

Dependencies used in this project

• ESPAsyncWebServer

ESP32

• AsyncTCP

ESP8266

• ESPAsyncTCP

Usage

For basic usage please see the examples folder.

To use the provided wifi manager html page you don't need to do anything except for set a define before you include the library header (for pio users see the Extras section)

Then, build and flash the SPIFFS image as normal.

For the ArduinoIDE you will need to follow a tutorial on SPIFFS and flash any custom html files using SPIFFS.

Warning

SPIFFS tools do not work yet in the ArduinoIDE 2.0. Support is coming soon.

Configuration

Warning

It is required to add a build flag to your setup for the code to function properly.

For platformio

build_flags = 
  -DASYNCWEBSERVER_REGEX ; add regex support to AsyncWebServer

Optionally you can enable the wifi manager and the async ota here as well:

build_flags = 
  -DASYNCWEBSERVER_REGEX ; add regex support to AsyncWebServer
  -DUSE_WEBMANAGER ; enable wifimanager
  -DUSE_ASYNCOTA ; enable async ota support

For ArduinoIDE:

Create, if missing, or update the platform.local.txt file.

The paths are:

Windows

Windows: C:\Users\(username)\AppData\Local\Arduino15\packages\espxxxx\hardware\espxxxx\{version}\platform.local.txt

Linux

Linux: ~/.arduino15/packages/espxxxx/hardware/espxxxx/{version}/platform.local.txt

The text to add is:

compiler.cpp.extra_flags=-DASYNCWEBSERVER_REGEX=1

Optionally you can enable the wifi manager here as well:

compiler.cpp.extra_flags=-DASYNCWEBSERVER_REGEX=1 -DUSE_WEBMANAGER=1

Warning

This library is still in development, if there are any bugs please report them in the issues section.

Modification

This library is intended to be modified and extended. If you find any bugs, please make a new issue and I will fix it.

If you have any questions, please ask in the discussions.

To extend any of the enums please use the data/utilities/enuminheritance.hpp file.

To use your own custom config, simply inherit from the CustomConfigInterface, override the save and load methods,and then register your config.

ConfigHandler configHandler("baseConf", MDNS_HOSTNAME);

class CustomConfig : public CustomConfigInterface {
    void save() override {
        this->log("Saving custom config");
    }

    void load() override {
        otherStuff();
        this->log("Loading custom config");
    }
    void otherStuff() {
      // do stuff
    }
};

CustomConfig customConfig;

// pass our custom config to the base config so that it can use it.
configHandler.config.registerUserConfig(&customConfig);

Extras

To see any of the log statements used in this library - you need to add this to your platformio.ini:

build_flags = 
  -DASYNCWEBSERVER_REGEX # add regex support to AsyncWebServer
  -DUSE_WEBMANAGER # enable wifimanager
  -DCORE_DEBUG_LEVEL=4 # add debug logging in serial monitor
  -std=gnu++17
build_unflags = -std=gnu++11

; other build parameters
monitor_filters = 
 esp32_exception_decoder
build_type = debug
lib_ldf_mode = deep

If you want to build in debug mode add this (it's not a build flag):

build_type = debug
