uint8_t

Function
Description
Scan all available APs. @attention If this API is called, the found APs are stored in WiFi driver dynamic allocated memory. And then can be freed in esp_wifi_scan_get_ap_records(), esp_wifi_scan_get_ap_record() or esp_wifi_clear_ap_list(), so call any one to free the memory once the scan is done. @attention The values of maximum active scan time and passive scan time per channel are limited to 1500 milliseconds. Values above 1500ms may cause station to disconnect from AP and are not recommended.
