cannot build with blank password #46

Closed mentaluproar closed 4 years ago

mentaluproar commented 5 years ago

When I try to build, make sets defaults. menuconfig lets me change those defaults, so I can change the name and password, but there is no option to change auth type. So when I leave a blank password, the esp just keeps crashing. Changes in the header dont work since they are overridden by kconfig during the build.

I need a way to set the password blank and the network type to open.

It's not a bug...

The AP starts up with WPA2 in mind - it needs an at least 8 char PW set. You would need to reconfigure the AP Startup as an unsecure/open station.

I maybe look into that, if I see the need for doing so for my own project.

    /* SoftAP - Wifi Access Point configuration setup */
    tcpip_adapter_ip_info_t info;
    memset(&info, 0x00, sizeof(info));
    wifi_config_t ap_config = {
        .ap = {
            .ssid_len = 0,
            .channel = wifi_settings.ap_channel,
            .authmode = WIFI_AUTH_OPEN,
            .ssid_hidden = wifi_settings.ap_ssid_hidden,
            .max_connection = DEFAULT_AP_MAX_CONNECTIONS,
            .beacon_interval = DEFAULT_AP_BEACON_INTERVAL,
        },
    };
    memcpy(ap_config.ap.ssid, wifi_settings.ap_ssid , sizeof(wifi_settings.ap_ssid));
    //memcpy(ap_config.ap.password, wifi_settings.ap_pwd, sizeof(wifi_settings.ap_pwd));

change the authmode and skip the password-memcpy. Should be as easy as that.
