WLAN initialization and connection to the SSID seems to work

and there was no further message from
the cb's wifi_status_cb or wifi_link_cb

but SYS:WIFI:STAT? says: -2,192.168.1.120,255.255.255.0,192.168.1.4

the connection to the ssid seems to be failed.... but why the cb's do not report that ?
AND
why the cyw43_arch_wifi_connect_async() returened 0 (means O.K.)

please see the following log:

with the modification in wifi_init() (HS_LOGON_WIFI ) it works fine.

A blemish that I have had for a long time remains:
The connection is not established until the second call of the function cyw43_arch_wifi_connect_timeout_ms()
see after the komment:
// that is very odd: try it again ... 2nd time and the connection will be established

void wifi_init()
{
#define HS_LOGON_WIFI	1
#if HS_LOGON_WIFI
    bool conn_ok = false;
    if (cyw43_arch_init()) {
        printf("failed to initialise\n");
        return;
    }

    cyw43_arch_enable_sta_mode();


    printf("Connecting to SSID: %s pw: %s\n", cfg->wifi_ssid, cfg->wifi_passwd);

    if (cyw43_arch_wifi_connect_timeout_ms(cfg->wifi_ssid, cfg->wifi_passwd, CYW43_AUTH_WPA2_AES_PSK, 30000)) {
        printf("failed to connect.\n");
        conn_ok = false;   // muths
    } else {
		conn_ok = true;
        printf("Connected.\n");
    }

    // that is very odd:  try it again ... 2nd time and the connection will be established
        
        if (!conn_ok){
            sleep_ms(1500);
            printf("second try to connect");
            if (cyw43_arch_wifi_connect_timeout_ms(cfg->wifi_ssid, cfg->wifi_passwd, CYW43_AUTH_WPA2_AES_PSK, 30000)) {

Just noticed that SYS:WIFI:STAT? returned link status -2, looking Pico-SDK that seems to mean

No matching SSID found(could be out of range, or down)."

Are you able to test if it works when closer to the AP?

Also, did you issue SYS:WIFI:STAT? immediately after unit completed booting? Does it eventually connect if you give it 20-30 seconds? (at least with DHCP it seems to take variable time for unit to obtain IP sometimes it connects really quick, but sometimes it take siginificantly longer...)

As a test, can you try setting IP to "0.0.0.0", so that it connects using DHCP? With DHCP does it seem to connect ok?

Does the AP have country code configured, if it does, then probably would be worth testing setting matching country code (using SYS:WIFI:COUNTRY).

thanks for quick answer!

the Pico_w is 4m near the AP.
with IP 0.0.0.0 the result is the same.

Do you see anything more useful if you enable more logging (SYS:LOG INFO)?

Since connection is done using cyw43_arch_wifi_connect_async() it will happen on the "background". I did quick test and it seems bit faster with static IP (compared to DHCP), but I couldn't replicate your issue...

It would seem like some incompatibility with your AP and the Radio in Pico W (unfortunately its 'black box'....)

Btw, looks like you have whitespace in your SSID (?), have you tested with SSID that doesn't have any special characters in it?

Have you tested any of the WiFi examples in https://github.com/raspberrypi/pico-examples ? Do those work or you get same problem?

I'm using the FRITZ!Box 7590 as AP.
I couldn't find there a CountryOption.
But with my test code using the cyw43_arch_wifi_connect_timeout_ms() function
and without cyw43_arch_init_with_country() ---> I use cyw43_arch_init()
it works fine.

as I explaned here

#44 (comment)

your code works fine with this little modification

The only difference ist
cyw43_arch_wifi_connect_timeout_ms() vs cyw43_arch_wifi_connect_async()

I added new command SYS:WIFI:MODE to allow specifying whether to use asynchronous (or synchronous) join to WiFi network.
