i have some problems with my code to connect to my home wifi network. This is my code:

Code: Select all#include <ets_sys.h>
#include <osapi.h>
#include <gpio.h>
#include <os_type.h>

void ICACHE_FLASH_ATTR user_set_station_config(void){
   char ssid[32] = "my_ssid";
   char password[64] = "my_password";
   struct station_config stationConf;

   os_memset(stationConf.ssid, 0, 32);
   os_memset(stationConf.password, 0, 64);
   //need not mac address
   stationConf.bssid_set = 0;

   //Set ap settings
   os_memcpy(&stationConf.ssid, ssid, 32);
   os_memcpy(&stationConf.password, password, 64);
   wifi_station_set_config(&stationConf);
   wifi_station_connect();
}

void user_init(void)
{
   wifi_set_opmode(STATIONAP_MODE);
   user_set_station_config();
}


The problem is, that i get the error message, that the struct size is not known (basically that means that the struct itself is unknown) and that 'STATIONAP_MODE' also isn't known.

I searched around and i found that the station_config struct is defined in the file 'esp_sta.h'. So i copied the file from the SDK folder into my 'include/driver' folder and added that line:

Code: Select all#include "driver/esp_sta.h"

Now at least the station_config error disappears but i get the error that the 'AUTH_MODE' is a unknown type in the 'esp_sta.h' file:

Code: Select allstruct bss_info {
    STAILQ_ENTRY(bss_info)     next;    /**< information of next AP */

    uint8 bssid[6];                     /**< MAC address of AP */
    uint8 ssid[32];                     /**< SSID of AP */
    uint8 ssid_len;                     /**< SSID length */
    uint8 channel;                      /**< channel of AP */
    sint8 rssi;                         /**< single strength of AP */
    AUTH_MODE authmode;                 /**< authmode of AP */ //ERROR appears HERE
    uint8 is_hidden;                    /**< SSID of current AP is hidden or not. */
    sint16 freq_offset;                 /**< frequency offset */
    sint16 freqcal_val;
    uint8 *esp_mesh_ie;
};

I am working with the the windows SDK from CHERTS.

Any ideas what i have to do to fix that?
