Does anybody know how to connect to hidden network using Native API on Gear S3 or Gear Fit2?

    int ret = WIFI_ERROR_NONE;
    ret = wifi_ap_hidden_create("blahblah", &ap);
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_ap_create failed %d", ret);
    }

    ret = wifi_ap_set_security_type(ap, WIFI_SECURITY_TYPE_WPA2_PSK);
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_ap_set_security_type failed %s", get_error_message(ret));
    }


    bool required = false;
    ret = wifi_ap_is_passphrase_required(ap, &required);
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_ap_is_passphrase_required failed %s", get_error_message(ret));
    }

    ret = wifi_ap_set_passphrase(ap, "passwdpasswd");
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_ap_set_passphrase failed %s", get_error_message(ret));
    }


    ret = wifi_initialize();
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_initialize failed %s", get_error_message(ret));
    }

    bool activated = false;
    ret = wifi_is_activated(&activated);
    if (ret != WIFI_ERROR_NONE) {
        ERR("wifi_is_activated failed %s", get_error_message(ret));
    }
    if (!activated) {
        DBG("WiFi not activated");
        ret = wifi_activate(wifiActivatedCb, &ap);
        if (ret != WIFI_ERROR_NONE) {
            ERR("wifi_activate failed %s", get_error_message(ret));
        }
    } else {
        DBG("WiFi activated");
        ret = wifi_connect(ap, wifiConnectedCb, NULL);
        if (ret != WIFI_ERROR_NONE) {
            ERR("wifi_connect failed %s", get_error_message(ret));
        }
    }

Unfortunately

wifi_connect

failed with message “opertion failed” error.

As almost always the error codes are totaly uselese in such cases.

Thanks in advance for help 😛 !!
