Wi-Fi scan configuration structure.

Indicates the configuration parameters for a Wi-Fi scan operation.

Note

• The Quick Scan feature is enabled when a specific channel and SSID are given for scanning. SiWx91x scans for the AP given in the scan API and posts the scan results immediately after finding the access point.

• The channel_bitmap_2g4 uses the lower 14 bits to represent channels from 1 to 14, where channel 1 = (1 << 0), channel 2 = (1 << 1), and so on.

• When channel_bitmap_2g4 is not set (value is 0), the device will scan all available channels.

• periodic_scan_interval is only applicable for SL_WIFI_SCAN_TYPE_ADV_SCAN of type sl_wifi_scan_type_t.

• To configure active_channel_time and passive_channel_time for active and passive scans, use the sl_wifi_set_advanced_scan_configuration() API with sl_wifi_advanced_scan_configuration_t.

• Channel scanning behavior:

  • For active scans: Scans the channels specified in channel_bitmap_2g4. If set to 0, scans all available channels. Can be configured as a subset of channels.

  • For background scans (SL_WIFI_SCAN_TYPE_ADV_SCAN): Scans the channels that were originally specified in channel_bitmap_2g4 during the first scan. The channel bitmap cannot be modified for background scans.

• 5 GHz is not supported.
