Any Samsung phone, new or old can send files via Bluetooth. It's slow but the only method I have left since Google in their infinite wisdom got rid of USB Mass Storage and Windows only sees my phone as a camera so it won't allow access to anything other than photos today if plugged into a PC.
You turn visibility on, on the device you want to receive the files, then go to your device you're sending from, and go to Bluetooth settings and look for the device. You then pair it like any headset, and then go to My Files (or whatever file browser you use) highlight what you want to send, be it a file, folder, or what, then tap 'share' (and whatever icon they chose to use!) and say 'send file via bluetooth' on the pop-up list. Then wait a couple of hours (yes it takes that long! one darned MP3!) You should be able to disable needing a pass code. That's going to be on the receiving device's Bluetooth settings (you can also change the name which shows up). The files should transfer like any other file. Whether or not your favorite ebook reader will see and access them, however, is anyone's guess. I didn't know Nook was still a thing (unless you meant Tom Nook!) I thought they EOL'd a long time ago. Last time I even saw a Nook tablet was when I picked up my Simple Touch at the K-Mart.
Wi-Fi direct, a Samsung specific feature, would be faster if it actually worked.
