im trying to connect my esp32cam in station mode to my home wifi so i can send the photos/data to another RPi3 so it can be analized, but still cant figure it out why it wont connect, any idea what it might be? i did follow the example from station_example.c that comes with the espressif library, i cannot use the serial monitor due an odd hardware glitch from the esp32cam-mb so i relay only on the onboard led for any info, i attach my code below
EDIT: the problem seems to be wifi_err = esp_wifi_init(&config_wifi); itss unable to initialized the wifi, but im using the same code from the example.
#include "start_server.h"

esp_wifi_connect();
} else if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_DISCONNECTED) {
if (s_retry_num < MAXIMUM_RETRY) {
esp_wifi_connect();
s_retry_num++;
//ESP_LOGI(TAG, "retry to connect to the AP");
} else {
xEventGroupSetBits(s_wifi_event_group, WIFI_FAIL_BIT);

//ESP_LOGI(TAG,"connect to the AP fail");
