2.4.1. Scan APIs
APIs to set the platform to AP mode are provided for your reference (see Table 12).
Table 12. Scan APIs
API Definition
wifi_connect_scan_init
(wifi_scan_list_item_t *ap_list,
uint32_t max_count)
This function should be called before calling the function
wifi_connection_start_scan()
, and it should be called
only once to initialize the scan to store the scanned AP list in the
ap_list
buffer in descending order of the RSSI, otherwise the
list won’t be stored.
wifi_connection_start_scan (uint8_t
*ssid, uint8_t ssid_length, uint8_t
*bssid, uint8_t scan_mode, uint8_t
scan_option)
This function starts the Wi-Fi Scanning based on scan mode and
scan option (see Table 8 and Table 9). The station mode supports
all scan modes and options. The AP mode supports only the
partial scan mode.
wifi_connection_stop_scan (void)
This function stops the Wi-Fi Scanning triggered by
