Wi-Fi Scan and Connect Appendix#

This appendix provides a glossary, acronyms, a summary of limitations, and references to further documentation.

For more detail on scanning and connection, refer to:

• Scan and Connect Parameter Tuning – wifi-scan-connect-parameter-effects.md – How scan and connection parameters affect scan duration, connection speed, roaming, and power.

Glossary#

• Active scan: A scan method that sends probe requests and listens for responses from the access points.

• Advanced scan: Background scan that runs while the device is connected to an AP. This scan is used for roaming.

• BSSID: Basic Service Set Identifier – the MAC address of an access point.

• Channel bitmap: A bit mask indicating which radio channels to scan (e.g., 2.4 GHz channels 1–14). In scan config use channel_bitmap_2g4; in client config use channel_bitmap.channel_bitmap_2_4.

• Credential ID: An identifier used to reference stored Wi-Fi credentials (PSK, EAP, etc.).

• Extended scan: A scan type that stores an unlimited number of results (memory permitting); results are retrieved with sl_wifi_get_stored_scan_results.

• Internal scan: The mandatory scan performed by sl_wifi_connect before attempting to join; not user-disabled.

• Passive scan: A scan method that only listens for beacons and probe responses without transmitting.

• Quick Scan: Scan mode enabled when both a single channel and an SSID are specified. The device scans only the specified channel for that SSID and can return as soon as the AP is found.

• PSK: Pre-shared key – a password used for WPA/WPA2/WPA3 personal security.

• RSSI: Received Signal Strength Indicator – signal strength in dBm.

• SSID: Service Set Identifier – the network name.
