Wi-SUN Stack API#

Wi-SUN Stack API is based on requests from the application to the stack and events from the stack to the application.

Requests are made using function calls, where a function call either performs the required action immediately or initiates an internal operation within the stack, which terminates with an event. All events contain a status code, indicating the result of the requested operation. Events are also used by the stack to notify the application of any important information, such as the state of the connection.

The application is expected to override sl_wisun_on_event() to handle events from the stack. Because all events share a common header, the function may be implemented as a switch statement. The event-specific data can be accessed through the sl_wisun_evt_t::evt union.

void sl_wisun_on_event(sl_wisun_evt_t *evt)
{
  switch (evt->header.id) {
    case SL_WISUN_MSG_CONNECTED_IND_ID:
      handle_connected_event(evt->evt.connected);
      break;
    default:
      break;
  }
}

The API is thread-safe, which means can be called from multiple RTOS tasks. The stack guarantees that only a single request is executed at a time and that requests are handled in the order they were made. Event callback is executed in a different context than the request, so the API functions may be called from the event callback.

Function Documentation#

sl_wisun_allow_mac_address#

sl_status_t sl_wisun_allow_mac_address (const sl_wisun_mac_address_t * address)

Add a MAC address to the list of allowed addresses.

Parameters
[in]address

MAC address

  • sl_wisun_broadcast_mac: allow all MAC addresses

  • unicast address: allow the given MAC address

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function adds a MAC address to the list of allowed addresses. When the first address is added to the list, the list of denied addresses is cleared and the device will start preventing communication with any device whose MAC address does not match any of addresses on the list. By default, all MAC addresses are allowed. Up to 10 MAC addresses may be added to the list. The access list affects only directly connected nodes such as parents, children, and neighbors.

sl_wisun_set_advert_fragment_duration#

sl_status_t sl_wisun_set_advert_fragment_duration (uint32_t fragment_duration_ms)

Set the async transmission fragmentation parameters.

Parameters
[in]fragment_duration_ms

Max duration of a fragment in ms (min 500 ms)

Returns

  • SL_STATUS_OK if successful, an error code otherwise

Async transmissions, such as Wi-SUN PAN advertisement packets, are sent to every allowed operating channel and may therefore block broadcast and unicast traffic. This impact can be reduced by splitting the channel list into fragments based on the maximum transmission duration and by forcing a delay between the fragments, allowing other traffic to occur. This function sets the maximum duration of a PA, PAS, PC, and PCS advertisement period fragments. A small value trades off longer connection times for shorter latencies. Setting the duration to SL_WISUN_ADVERT_FRAGMENT_DISABLE disables async transmission fragmentation.

By default, the maximum fragment duration is set to 500 ms.

Set the device MAC address to be used.

Parameters
[in]address

MAC address

Returns

Set the PHY mode switch configuration.

Parameters
[in]mode

Mode switch configuration of the neighbor. If set to SL_WISUN_MODE_SWITCH_DEFAULT, the configuration of the neighbor is reset back to the default mode switch behavior.

[in]phy_mode_id

PhyModeId to use when mode is set to SL_WISUN_MODE_SWITCH_ENABLED, ignored otherwise.

[in]neighbor_address

MAC address of the neighbor to configure. If set to sl_wisun_broadcast_mac, configures the default mode switch behavior for all non-configured neighbors.

Returns

  • SL_STATUS_OK if successful, an error code otherwise

sl_wisun_set_neighbor_table_size#

sl_status_t sl_wisun_set_neighbor_table_size (uint8_t size)

Set neighbor table size.

Parameters
[in]size

Size of the neighbor table

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets the limit of regular neighbors supported by the node [1, 245], without considering temporary or RPL parents. Increasing this parameter means a higher number of potential neighbors while lowering it means reduced RAM consumption. The default value is 22.

Set the POM-IE configuration.

Parameters
[in]phy_mode_id_count

Number of PhyModeId to configure

[in]phy_mode_ids

List of phy_mode_id_count PhyModeId. It must contain the base operating mode.

[in]is_mdr_command_capable

Indicate if the device supports MAC mode switch. Feature currently unsupported, must be set to 0.

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets the PHY operating mode information advertised to neighboring nodes. By default the PhyModeId list contains the first fifteen PhyModeId listed in radio multi-PHY configuration, MAC mode switch is disabled.

sl_status_t sl_wisun_set_pti_state (bool pti_state)

Set the PTI state.

Parameters
[in]pti_state

PTI state

  • true: PTI is enabled

  • false: PTI is disabled

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets Packet Trace Interface (PTI) state. PTI is enabled by default.

sl_wisun_set_regulation#

sl_status_t sl_wisun_set_regulation (sl_wisun_regulation_t regulation)

Set the regional regulation.

Parameters
[in]regulation

Regional regulation

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets the regional regulation for use in the following connections. The selected regional regulation will impact both the Wi-SUN stack performance and its behavior. See regulation standards for details. No regulation is set by default.

sl_wisun_set_regulation_tx_thresholds#

sl_status_t sl_wisun_set_regulation_tx_thresholds (int8_t warning_threshold, int8_t alert_threshold)

Set the thresholds for transmission duration level event.

Parameters
[in]warning_threshold

Warning threshold in percent or -1 to disable

[in]alert_threshold

Alert threshold in percent or -1 to disable

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets the thresholds for transmission duration level event. When set and when a regional regulation is enabled using sl_wisun_set_regulation(), a SL_WISUN_MSG_REGULATION_TX_LEVEL_IND_ID event is sent when one of the configured thresholds is exceeded. This can be used by the application to prevent exceeding the total transmission duration allowed in the regional regulation. Thresholds are defined as a percentage of the maximum transmission duration permitted by the regional regulation.

sl_wisun_set_security_state#

sl_status_t sl_wisun_set_security_state (uint32_t security_state)

Set the connection security state.

Parameters
[in]security_state

Connection security state

  • 0: Authentication and link encryption are disabled

  • 1: Authentication and link encryption are enabled

Returns

  • SL_STATUS_OK if successful, an error code otherwise

This function sets the connection security state. By default, authentication and link encryption are enabled. The function is intended for test purposes.

Note

  • Authentication and link encryption can only be disabled when the application is linked against a library supporting this option.

  • Available in libraries: Full, FFN, LFN (see Wi-SUN API availability)
