WiFi connection and memory error main program

[Gaston1980]

Hi to all, I tested a WiFi connection in a project with success and everything works like a charm!!! Now I'm trying to use this peace of code with a main program and memory problems came up. This is the memory map of the program.


I use this peace of code to init the wifi:

Code: Select all

    nvs_flash_init();
    err_t err = wifi_connection();   
    vTaskDelay(3000 / portTICK_PERIOD_MS);
    ESP_LOGI(TAG1,"WIFI was initiated ...........\n\n");
    esp_netif_get_ip_info(my_staif, &ipInfo.ip);
    printf("My IPV4: " IPSTR "\n", IP2STR(&ipInfo.ip));

which calls this other code:

Code: Select all

    esp_netif_init();                    // TCP/IP initiation 					s1.1
    esp_event_loop_create_default();     // event loop 			                s1.2
    my_staif = esp_netif_create_default_wifi_sta(); // WiFi station 	                    s1.3
    wifi_init_config_t wifi_initiation = WIFI_INIT_CONFIG_DEFAULT();
    esp_wifi_init(&wifi_initiation); // 					                    s1.4
    // 2 - Wi-Fi Configuration Phase
    esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, wifi_event_handler, NULL);
    esp_event_handler_register(IP_EVENT, IP_EVENT_STA_GOT_IP, wifi_event_handler, NULL);
    wifi_config_t wifi_configuration = {
        .sta = {
            .ssid = "",
            .password ="",   
            .threshold.authmode = WIFI_AUTH_WPA2_PSK,       
            }
            };
    strcpy((char*)wifi_configuration.sta.ssid,SSID);
    strcpy((char*)wifi_configuration.sta.password,PASS);
    esp_wifi_set_config(ESP_IF_WIFI_STA, &wifi_configuration);
    esp_wifi_start();
    esp_wifi_set_mode(WIFI_MODE_STA);
    esp_wifi_connect();
    esp_wifi_get_ps(0);

In my main program I use a large array to be transfer via wifi which in case of no memory will show message. And I got the messsage about memory being not enough!!!

a few question:
1) It seems to me that I have more memory to be used but why this error?
2) Why if I comment the wifi connection the program works without problems?
3) Do I need to free memory after WiFi connection?

P.S: I already use menuconfig to use another partition table with more memory.

By the way ...Im using esp32 32E wroom kit to take pics with ov7670 and just to be sure...could this be related to a memory heap issue due to WiFi? using ov7670 and res 320x240 seem to be a problem with this esp32.
