As in the subject, I can't connect to any network that uses e.g. WPA2, when there is network without password it connects everytime.
connectTo method:

Code: Untitled.cpp Select all

bool WifiDriver::connectTo(const SSIDstring& ssid, const PSKstring& password) {

    if (k_sem_count_get(&connectionSemaphore) > 0) {

        return false;

    }

    strncpy(reinterpret_cast<char*>(_ssid), ssid.c_str(), WIFI_SSID_MAX_LEN);

    _wifiParams.ssid_length = ssid.length();

    strncpy(

        reinterpret_cast<char*>(_password), password.c_str(), WIFI_PSK_MAX_LEN);

    _wifiParams.psk_length = password.length();



    _wifiParams.sae_password_length = password.length();



    printk("before connection request\n");

    int res = net_mgmt(NET_REQUEST_WIFI_CONNECT,

                 _netInterface,

                 &_wifiParams,

                 sizeof(_wifiParams));

    if (res) {

        printk("connection request failed: %d\n", res, strerror(res));

        return false;

    }

    printk("connection succeded\n");

    _connected = true;

    return true;

}

Init method:

Code: Untitled.cpp Select all

void WifiDriver::init() {

    k_sem_init(&connectionSemaphore, 0, 1);



    net_mgmt_init_event_callback(

        &_wifiCallback,

        WifiDriver::wifiCallbackHandler,

        NET_EVENT_WIFI_CONNECT_RESULT | NET_EVENT_WIFI_DISCONNECT_RESULT);



    net_mgmt_init_event_callback(&_ipv4Callback,

                                 WifiDriver::ipv4CallbackHandler,

                                 NET_EVENT_IPV4_ADDR_ADD);



    net_mgmt_add_event_callback(&_wifiCallback);

    net_mgmt_add_event_callback(&_ipv4Callback);



    _netInterface = net_if_get_default();

    if (_netInterface == NULL) {

        printk("net_if_get_default failed! No default interface configured!\n");

    }



    _wifiParams.ssid = _ssid;

    _wifiParams.ssid_length = 0;

    _wifiParams.psk = _password;

    _wifiParams.psk_length = 0;

    _wifiParams.sae_password = _password;

    _wifiParams.sae_password_length = 0;

    _wifiParams.band = WIFI_FREQ_BAND_2_4_GHZ;

    _wifiParams.channel = WIFI_CHANNEL_ANY;

    _wifiParams.security = WIFI_SECURITY_TYPE_UNKNOWN;

    _wifiParams.mfp = WIFI_MFP_DISABLE;

    _wifiParams.timeout = SYS_FOREVER_MS;



    _connected = false;

}
