The AP router operates in WPA2PSK authentication mode
1)
In this example, the AP router operates in WPA2PSK authentication mode with AES encryption type, the
password is "
12345678
" and the SSID of the AP router is "
REMOTE_AP
". Initialize the module in STA mode,
as shown below.
a)
Define the operation mode (
config.opmode
), password (
config.sta_config.password
) and
the SSID (
config.sta_config.ssid
) in the
wifi_config_t
structure.
wifi_config_t config = {0};
config.opmode = WIFI_MODE_STA_ONLY;
strcpy((char *)config.sta_config.ssid, "
REMOTE
_AP");
config.sta_config.ssid_length = strlen((char *)config.sta_config.ssid);
strcpy((char *)config.sta_config.password, "12345678");
config.sta_config.password_length = strlen((char
*)config.sta_config.password);
b)
Call the
wifi_init()
function to initialize the Wi-Fi driver.
wifi_init(&config, NULL);
The STA mode supports various types of security modes, as shown in Table 4. For more information about the
authentication mode and encryption group types, refer to
wifi_auth_mode_t
and
wifi_encrypt_type_t
types in the Wi-Fi API reference guide.

2)
To use configuration APIs in STA mode to connect to the AP router:
a)
Call the
wifi_config_set_opmode()
function to set the opmode to WIFI_MODE_STA_ONLY.
wifi_config_set_opmode(WIFI_MODE_STA_ONLY);
b)
Call the
wifi_config_set_ssid()
function to set the port to WIFI_PORT_STA and the SSID to
"
REMOTE_AP
".
wifi_config_set_ssid(WIFI_PORT_STA, "
REMOTE_AP"
, strlen("
REMOTE_AP
"));
c)
Set the password to "12345678" by calling the
wifi_config_set_wpa_psk_key()
function.
wifi_config_set_wpa_psk_key(WIFI_PORT_STA, "12345678",
strlen("12345678"));
d)
Apply the parameters by calling the
wifi_config_reload_setting()
function.
