sl_wifi_init#

sl_status_t sl_wifi_init (const sl_wifi_device_configuration_t * configuration, sl_wifi_device_context_t * device_context, sl_wifi_event_handler_t event_handler)

This function initializes the Wi-Fi module using the specified device configuration, device context, and event handler.

It configures the Wi-Fi device and establishes the event handler for Wi-Fi events. This function must be called before using any other Wi-Fi functions. Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

Note

• This function should be called before calling any other sl_wifi functions.

sl_wifi_deinit#

sl_status_t sl_wifi_deinit (void )

This function ensures proper shutdown of the Wi-Fi driver, resetting configurations and releasing resources.

Call this API to deinitialize the Wi-Fi module to avoid resource leaks

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

sl_wifi_is_interface_up#

bool sl_wifi_is_interface_up (sl_wifi_interface_t interface)

Check if Wi-Fi interface is up.

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• 1. true: interface is up.

  2. false: interface is down.

sl_wifi_get_firmware_version#

sl_status_t sl_wifi_get_firmware_version (sl_wifi_firmware_version_t * version)

Return the firmware version running on the Wi-Fi device.

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

Note

• Moving forward, this API will be deprecated. Instead, please use the sl_si91x_get_firmware_version API.

sl_wifi_get_wireless_info#

sl_status_t sl_wifi_get_wireless_info (sl_si91x_rsp_wireless_info_t * info)

Gets wlan info in AP mode / Client mode.

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

sl_wifi_get_firmware_size#

sl_status_t sl_wifi_get_firmware_size (void * buffer, uint32_t * fw_image_size)

Return the firmware image size from firmware image.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

Note

• Moving forward, this API will be deprecated. Instead, please use the sl_si91x_get_firmware_size API.

sl_wifi_set_default_interface#

void sl_wifi_set_default_interface (sl_wifi_interface_t interface)

Set the default Wi-Fi interface as supported by sl_wifi_interface_t.

sl_wifi_get_default_interface#

sl_wifi_interface_t sl_wifi_get_default_interface (void )

Get the default interface.

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• sl_wifi_interface_t previously set by sl_wifi_set_default_interface

sl_wifi_get_mac_address#

sl_status_t sl_wifi_get_mac_address (sl_wifi_interface_t interface, sl_mac_address_t * mac)

Retrieves the MAC addresses of the specified Wi-Fi interface, in concurrent mode retrieves two MAC addresses.

MAC address of the module. In concurrent mode, two MAC addresses are returned, MAC_Address1 is the station MAC address and MAC_Address2 is the created AP MAC address. MAC address is returned in 6-bytes in hex format.

• Pre-conditions:

  • sl_wifi_init should be called before this API.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

sl_wifi_set_mac_address#

sl_status_t sl_wifi_set_mac_address (sl_wifi_interface_t interface, const sl_mac_address_t * mac)

Set the Wi-Fi interface MAC address.

Returns

• sl_status_t. See https://docs.silabs.com/gecko-platform/4.1/common/api/group-status for details.

Note

• This API is not supported by Si917 when called directly due to firmware constraints. Alternatively, sl_wifi_init can be used to configure the MAC address. sl_wifi_init ensures the appropriate state of firmware and calls this API to set MAC address.
