-The :cpp:type:`mesh_event_id_t` defines all possible ESP-MESH system events and can indicate events such as the connection/disconnection of parent/child. Before ESP-MESH system events can be used, the application must register a **Mesh Event Callback** via :cpp:func:`esp_mesh_set_config`. The callback is used to receive events from the ESP-MESH stack as well as the LwIP Stack and should contain handlers for each event relevant to the application.
+The :cpp:type:`mesh_event_id_t` defines all possible ESP-MESH events and can indicate events such as the connection/disconnection of parent/child. Before ESP-MESH events can be used, the application must register a **Mesh Events handler** via :cpp:func:`esp_event_handler_register` to the default event task. Should contain handlers for each event relevant to the application.
 
-Typical use cases of system events include using events such as :cpp:enumerator:`MESH_EVENT_PARENT_CONNECTED` and :cpp:enumerator:`MESH_EVENT_CHILD_CONNECTED` to indicate when a node can begin transmitting data upstream and downstream respectively. Likewise, :cpp:enumerator:`MESH_EVENT_ROOT_GOT_IP` and :cpp:enumerator:`MESH_EVENT_ROOT_LOST_IP` can be used to indicate when the root node can and cannot transmit data to the external IP network.

 .. warning::
     When using ESP-MESH under self-organized mode, users must ensure that no calls to Wi-Fi API are made. This is due to the fact that the self-organizing mode will internally make Wi-Fi API calls to connect/disconnect/scan etc. **Any Wi-Fi calls from the application (including calls from callbacks and handlers of Wi-Fi events) may interfere with ESP-MESH's self-organizing behavior**. Therefore, user's should not call Wi-Fi APIs after :cpp:func:`esp_mesh_start` is called, and before :cpp:func:`esp_mesh_stop` is called.
