Application Core API type definitions

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().

bool
app_wisun_get_regulation_thresholds(regulation_thresholds_t *thresholds_out)

app_wisun_project_info_init#

void app_wisun_project_info_init (const char * app_name)

Initialize Wi-SUN project information.

Parameters

Init internal instance


app_wisun_project_info_print#

void app_wisun_project_info_print (const bool json_format)

Print Wi-SUN project information.

Parameters
TypeDirectionArgument NameDescription
const bool[in]json_format

Json format required indicator

Print project info in pretty or json format.


app_wisun_wait_for_connection#

void app_wisun_wait_for_connection (void )

Wait for the connection.

Parameters
TypeDirectionArgument NameDescription
voidN/A

This function doesn't call the app_wisun_network_connect() function. The function provides a delay loop with optional heart beat printing till the connection state has not been changed.


app_wisun_connect_and_wait#

void app_wisun_connect_and_wait (void )

Connect and wait for connection.

Parameters
TypeDirectionArgument NameDescription
voidN/A

The function calls app_wisun_network_connect() function and app_wisun_wait_for_connection() function. It can be useful at the beginning of application thread.


app_wisun_network_is_connected#

bool app_wisun_network_is_connected (void )

The network is connected.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Wrapper function of join state getter Returns

  • true Connected

  • false Not connected


Function Documentation#

app_wisun_core_init#

void app_wisun_core_init (void )

Initialize Wi-SUN application core.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Initializing mutex, socket handler and set Wi-SUN settings.


app_wisun_core_get_error#

bool app_wisun_core_get_error (app_core_error_state_flag_t flag)

Get application core error.

Parameters
TypeDirectionArgument NameDescription
app_core_error_state_flag_t[in]flag

is the indicator of the error

The function retrieves the application core error status based on the flag. Returns

  • bool True if error flag is set, otherwise false


app_wisun_network_connect#

void app_wisun_network_connect (void )

Connect to the Wi-SUN network.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Network initialization and connection. The function initializes the network with parameters (Network name, TX Power, Network size, etc.) by the stored settings in NVM if the settings component is added to the project, otherwise with the default settings.

void app_wisun_set_regulation_active (bool enabled)

Set the regional regulation to active or passive.

Parameters

(true = active, false = not active)

After a stack API call for regional regulation, this function can be used to store the status of the regulation (active or not).
