NOT CONNECTING TO WIFI WHEN PASSING AS PARAMETERS BY CREATING AS FUNCTION (IDFGH-8623)

[beginner140BB]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I need to create a simple function for wifi initialisation (as AP )using espressif ide platform have found that when passing as arguments its not working.

wifi_config_t wifi_config1 ;
printf("before structure ssid %s\n",wifi_config1.sta.ssid);
printf("before structure pswd %s\n",wifi_config1.sta.password);
strcpy( (char *)wifi_config1.sta.ssid ,ssid);
printf("structure ssid %s\n",wifi_config1.sta.ssid);
strcpy((char *)wifi_config1.sta.password ,pass);
printf("structure pswd %s\n",wifi_config1.sta.password);
wifi_config1.sta.threshold.authmode = ESP_WIFI_SCAN_AUTH_MODE_THRESHOLD;

when printing the structure the ssid and password is there in the array.
don,t know what makes the issue here.

the output log is

before structure ssid ���?���?
�p��?╚ structure pswd �^
structure ssid IDCESP2
structure pswd 12345678

This is the function i am using

HI , please can you share with me the solution of this issue

HI , please can you share with me the solution of this issue

just pass the parameters and please have a look at the example code in esp-idf

https://sourcegraph.com/github.com/espressif/esp-idf/-/blob/examples/wifi/getting_started/station/main/station_example_main.c

char Wifi_init(char *ssid, char *pass)
{
    wifi_config_t wifi_config = {
        .sta = {
	     .threshold.authmode = ESP_WIFI_SCAN_AUTH_MODE_THRESHOLD,
        },
    };
    strcpy( (char *)wifi_config.sta.ssid ,ssid);
    strcpy( (char *)wifi_config.sta.password ,pass);
    
    esp_wifi_set_mode(WIFI_MODE_STA);
    esp_wifi_set_config(WIFI_IF_STA, &wifi_config);
    esp_wifi_start();
    
    }
