Application Core#

The Application Core component provides utilities common to most Wi-SUN applications with the following features:

  • A Wi-SUN connection helper function app_wisun_network_connect() configures the network size setting, the TX output power, the certificates, and keys. The last function action is to start the Wi-SUN connection process. The app_wisun_network_is_connected() function provides a simple connection status getter too.

  • Event handlers for basic Wi-SUN network events component includes the basic event handler implementations.

  • Available addresses. Retrieve known IPv6 addresses with the app_wisun_get_current_addresses() function.

  • Error Getter. Use app_wisun_core_get_error() function to get the status of the Stack API calls.

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

The Application Core component is designed to offer essential utilities commonly used in Wi-SUN applications with the following features:
