Can't get product manufacturer attribute in my custom module

Question

I already searched here, but none answers have work.

I have a custom module, where I get a list of products from one category setted by user, it is coded in a Helper class:

public function getConfigCategory()
{
    $category = $this->_categoryFactory->create()->load('CONFIGURATION');
    return $category;
}

public function getFilteredProducts()
{
    return $this->getConfigCategory()->getProductCollection()->addAttributeToSelect('*'); 
}

So, with this I have a list of products, wich one foreach (in a Model class), but when I try to get the manufacturer attribute, it always return null.

$brand = $product->getAttributeText('manufacturer');

$brand is always null, I have tried to reload $product with this:

$product = $this->objectManager->get('Magento\Catalog\Model\Product')->load($product->getId());

But the result is always the same, any ideia? Thanks in advance.

I'm using the sample data, and I have bundle items

You could try:

<?php echo $_product->getResource()->getAttribute('manufacturer')->getFrontend()->getValue($_product); ?>

You may need to set your attribute up so attribute is visible in frontend also, this may solve your problem.
