I've come across a couple of products that shows up as both classic and BLE. But when connecting to these products via nRF Connect or inspecting the traffic, I can't seem to find any GATT services. One example is the Bose QuietComfort 35 headphones, another one is the iHealth HS4S scale.
Is there a specific reason for these products to enable BLE at all? Are they using BLE for something else than GATT?
