API :cpp:func:`esp_wifi_set_config()` can be used to configure the AP. And the configuration will be stored in NVS. The table below describes the fields in detail.
+------------------+--------------------------------------------------------------+
| Field | Description |
+==================+==============================================================+
| ssid | SSID of AP; if the ssid[0] is 0xFF and ssid[1] is 0xFF, |
| | the AP defaults the SSID to ESP_aabbcc, where "aabbcc" |
| | is the last three bytes of the AP MAC. |
| | |
+------------------+--------------------------------------------------------------+
| password | Password of AP; if the auth mode is WIFI_AUTH_OPEN, |
| | this field will be ignored. |
| | |
+------------------+--------------------------------------------------------------+
| ssid_len | Length of SSID; if ssid_len is 0, check the SSID until there |
| | is a termination character. If ssid_len > 32, change it to |
| | 32; otherwise, set the SSID length according to ssid_len. |
| | |
+------------------+--------------------------------------------------------------+
| channel | Channel of AP; if the channel is out of range, the Wi-Fi |
| | driver defaults the channel to channel 1. So, please make |
| | sure the channel is within the required range. |
| | For more details, refer to `Wi-Fi Country Code`_. |
+------------------+--------------------------------------------------------------+
| authmode | Auth mode of ESP AP; currently, ESP Wi-Fi does not |
| | support AUTH_WEP. If the authmode is an invalid value, |
| | AP defaults the value to WIFI_AUTH_OPEN. |
| | |
+------------------+--------------------------------------------------------------+
| ssid_hidden | If ssid_hidden is 1, AP does not broadcast the SSID; |
| | otherwise, it does broadcast the SSID. |
| | |
+------------------+--------------------------------------------------------------+
| max_connection | Currently, ESP Wi-Fi supports up to 10 Wi-Fi connections. |
| | If max_connection > 10, AP defaults the value to 10. |
| | |
+------------------+--------------------------------------------------------------+
| beacon_interval | Beacon interval; the value is 100 ~ 60000 ms, with default |
| | value being 100 ms. If the value is out of range, |
| | AP defaults it to 100 ms. |
