- Wed Apr 22, 2015 12:49 pm #15294 Hello and thank you all for this wonderful community.

I have been trying to make some code for connecting to an AP. The initial plan was, connect to a configured network, if not create a SoftAP, and present a configuration page.
This went well, until I realised that my code for connecting to the AP did not work. When I use my code for, it fails when I call "wifi_station_connect", then the autoconnect feature connects without complaining.
The full code is at github https://github.com/deadbok/WIFISwitch, but I have tried putting everything in user_init() without success. If I turn off autoconnect, the code newer connects.

user_main.c:

Code: Select all#define user_procTaskPrio        0
#define user_procTaskQueueLen    1
os_event_t    user_procTaskQueue[user_procTaskQueueLen];
static void wifi_status(os_event_t *events);
static volatile os_timer_t some_timer;

void some_timerfunc(void *arg)
{
    os_printf("Connections status: %d\n", wifi_station_get_connect_status());
}

/* Main entry point.
 */
void ICACHE_FLASH_ATTR user_init()
{
    unsigned char   connection_status;
    struct station_config station_conf = { "default", "password", 0, "000000"};

    wifi_set_opmode(STATION_MODE);
    //Turn on auto connect.
    wifi_station_set_auto_connect(true);
   
    // Set baud rate of debug port
    uart_div_modify(0,UART_CLK_FREQ / 115200);
   
    os_delay_us(1000);
   
    //Print banner
    os_printf("\nWIFISwitch version %s.\n", STRING_VERSION);
    system_print_meminfo();
    os_printf("Free heap %u\n", system_get_free_heap_size());   
   
    os_printf("\n\n\n\n");
       
    //Disarm timer
    os_timer_disarm(&some_timer);

    //Setup timer
    os_timer_setfn(&some_timer, (os_timer_func_t *)some_timerfunc, NULL);

    //Arm the timer
    os_timer_arm(&some_timer, 500, 1);
       
    if (!wifi_station_set_config(&station_conf))
    {
        os_printf("Failed to set station configuration.\n");
    }
       
    if (!wifi_station_connect())
    {
        os_printf("Main: Failed to connect to AP.\n");
     }
}

output:

i am pretty certain, that there's something obvious I'm am missing, and I think code, much like this worked when I started. I hope somebody can tell me what I am doing wrong.

Thank you

- Thu Apr 23, 2015 6:27 am #15358 I have made a simple test program that waits while connecting to an AP. This works, and uses timers to check if the connection is up. I will try and rework the above code towards this.
