Utilities

Application Core#

The Application Core component aims at providing utilities common to most Wi-SUN applications. Following this objective, the component offers the following features:

  • A Wi-SUN connection helper function app_wisun_network_connect(). This function configures the network size setting, the TX output power, the certificates, and keys. The last function action is to start the catual Wi-SUN connection process.

  • An event handler and callback mechanisms. It provides a thread-safe abstraction layer on the Wi-SUN stack events reported in sl_wisun_on_event(). Two APIs (app_wisun_register_custom_callback() and app_wisun_remove_custom_callback()) are exposed to the application to add or remove custom callbacks associated with stack events.

  • A ping capability through the app_wisun_ping() function. It can be used to test communications and latencies in a Wi-SUN network.

  • A Socket FIFO overflow handler. The application can redefine the weakly implemented app_wisun_socket_fifo_overflow_handler() function to handle the socket FIFO overflow events.

  • A graphical interface in Simplicity Studio to configure the network name, TX power, and network size to be used during the connection process.

To use the component in your application, add it to your project and initialize it with app_wisun_core_init().
