I need to sniffer around macs, and then post them to android phone via BLE.
But It comes to error.
my code is

// init wifi sniffer
    esp_err_t ret;
    // Initialize NVS
    ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES)
    {
        ESP_ERROR_CHECK(nvs_flash_erase());
        ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK(ret);

    
    tcpip_adapter_init();
    one_shot_timer_start();

    ESP_ERROR_CHECK(esp_event_loop_init(event_handler, NULL));

    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK(esp_wifi_init(&cfg));
    ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_RAM));

    // ESP_ERROR_CHECK(esp_wifi_set_promiscuous_filter(WIFI_PROMIS_FILTER_MASK_MGMT));
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous_rx_cb(wifi_promiscuous_cb));
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous(true));
    
    // ble init
    
    
    esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT();
    ret = esp_bt_controller_init(&bt_cfg);
    if (ret) {
        ESP_LOGE(GATTS_TAG, "%s initialize controller failed\n", __func__);
        return;
    }

    ret = esp_bt_controller_enable(ESP_BT_MODE_BTDM);
    if (ret) {
        ESP_LOGE(GATTS_TAG, "%s enable controller failed\n", __func__);
        return;
    }
    ret = esp_bluedroid_init();
    if (ret) {
        ESP_LOGE(GATTS_TAG, "%s init bluetooth failed\n", __func__);
        return;
    }
    ret = esp_bluedroid_enable();
    if (ret) {
        ESP_LOGE(GATTS_TAG, "%s enable bluetooth failed\n", __func__);
        return;
    }

    ret = esp_ble_gatts_register_callback(gatts_event_handler);
    if (ret){
        ESP_LOGE(GATTS_TAG, "gatts register error, error code = %x", ret);
        return;
    }
    ret = esp_ble_gap_register_callback(gap_event_handler);
    if (ret){
        ESP_LOGE(GATTS_TAG, "gap register error, error code = %x", ret);
        return;
    }
    ret = esp_ble_gatts_app_register(PROFILE_A_APP_ID);
    if (ret){
        ESP_LOGE(GATTS_TAG, "gatts app register error, error code = %x", ret);
        return;
    }
    
    // ret = esp_ble_gatts_app_register(PROFILE_B_APP_ID);
    // if (ret){
    //     ESP_LOGE(GATTS_TAG, "gatts app register error, error code = %x", ret);
    //     return;
    // }

    esp_err_t local_mtu_ret = esp_ble_gatt_set_local_mtu(500);
    if (local_mtu_ret){
        ESP_LOGE(GATTS_TAG, "set local  MTU failed, error code = %x", local_mtu_ret);
    }

I think it would probably help if you related your posted code to file names and line numbers. In the trace we see errors in "file X" and "line Y" but in your pasted code, we can't map those back to which line in your source caused the exception.

By looking at amount of free heap i can say its most likely the reason:

I (1404) heap_init: At 3FFAFF10 len 000000F0 (0 KiB): DRAM
I (1423) heap_init: At 3FFD9270 len 00006D90 (27 KiB): DRAM

I have similar errors with even more free DRAM when i try to run WiFi with BLE.

Actually, there still is a (somewhat low but perfectly usable) amount of DRAM available: the D/IRAM regions can be used as both DRAM as well as IRAM.

I'm not entirely sure what's going on here... it seems like the creation of an internal task failed, even before app_main is called, because there's not enough memory available. Could you maybe have modified the stack sizes for various tasks (idle, timers, ...) in menuconfig in such a way they take up so much memory that there's none left for internal tasks?
