When trying to free up BT classic memory in blufi example i get the following crash. Is it expected that BT classic should be present when using blufi profile? My understanding is that it is BTLE profile. Please let me understand if it is real issue or i am incorrectly using it.

Code: void ble_task(void *pvParameters) { esp_err_t ret;

esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT();
ret = esp_bt_controller_init(&bt_cfg);
if (ret) {
    ESP_LOGI(TAG, "Initialize bt controller failed\n");
    return;
}

ret = esp_bt_controller_enable(ESP_BT_MODE_BLE);
if (ret) {
    ESP_LOGI(TAG, "Enable bt controller failed\n");
    return;
}

// Release classic BT memory
esp_bt_controller_mem_release(ESP_BT_MODE_BTDM);

ret = esp_bluedroid_init();
if (ret) {
    ESP_LOGI(TAG, "Init bluedroid failed\n");
    return;
}

ret = esp_bluedroid_enable();
if (ret) {
    ESP_LOGI(TAG, "Init bluedroid failed\n");
    return;
}

ESP_LOGI(TAG, "BD ADDR: "ESP_BD_ADDR_STR"\n", ESP_BD_ADDR_HEX(esp_bt_dev_get_address()));
ESP_LOGI(TAG, "BLUFI VERSION %04x\n", esp_blufi_get_version());

blufi_security_init();
esp_ble_gap_register_callback(ble_gap_event_handler);

esp_blufi_register_callbacks(&blufi_event_callback);
esp_blufi_profile_init();

vTaskDelete(NULL);

}
