Depends on your threat model. Generally probably not, but there's always a risk, and network stacks are not becoming simpler. There are disclosure risks - bluetooth trackers are common in retail stores. I disable Bluetooth on almost everything, not so much for "security" as because I don't need it, so there's no reason for it. I don't like things in my ears, so it is of no benefit to me on my phone, and I don't feel a burning desire to provide real-world unique identifiers to in-store surveillance, so I don't. I also don't use a wireless keyboard or other toys like that, so my other machines don't need it either. Last use I had for Bluetooth was getting data from a battery charger. That lasted long enough for me to discover I didn't care about the data.
