What is esp32-wifi-manager?

esp32-wifi-manager is an esp32 program that enables easy management of wifi networks through a web application.

esp32-wifi-manager is lightweight (8KB of task stack in total) and barely uses any CPU power through a completely event driven architecture. It's an all in one wifi scanner, http server & dns daemon living in the least amount of RAM possible.

For real time constrained applications, esp32-wifi-manager can live entirely on PRO CPU, leaving the entire APP CPU untouched for your own needs.

esp32-wifi-manager will automatically attempt to re-connect to a previously saved network on boot, and it will start its own wifi access point through which you can manage wifi networks if a saved network cannot be found and/or if the connection is lost.

esp32-wifi-manager is an esp-idf project that compiles successfully with the esp-idf 3.2 release. You can simply copy the project and start adding your own code to it.

Adding esp32-wifi-manager to your code

Ther are effectively three different ways you can embed esp32-wifi-manager with your code:

• Just forget about it and poll in your code for wifi connectivity status
• Use event callbacks
• Modify esp32-wifi-manager code directly to fit your needs

Event callbacks are the cleanest way to use the wifi manager and that's the recommended way to do it. A typical use-case would be to get notified when wifi manager finally gets a connection an access point. In order to do this you can simply define a callback function:

void cb_connection_ok(void *pvParameter){
	ESP_LOGI(TAG, "I have a connection!");
}

Then just register it by calling:

wifi_manager_set_callback(EVENT_STA_GOT_IP, &cb_connection_ok);

That's it! Now everytime the event is triggered it will call this function.
