People emitting Bluetooth

Using an app called Bluetooth Scanner - Bluetooth finder - pairing by Zoltán Pallagi.
The app gives you a visual image of what the device is

For each device there is a button called More.. On tapping this, take note of the first line
"Device Major Class Code". The unknowns are 7936. The Oppo phone had a code of 512. This is part of the Java programming language

Here are the other codes: AUDIO_VIDEO(1024), COMPUTER(256), HEALTH(2304), IMAGING(1536), MISC(0), NETWORKING(768), PERIPHERAL(1280), PHONE(512), TOY(2048), UNCATEGORIZED(7936), WEARABLE(1792)
See here for reference https://stuff.mit.edu/afs/sipb/project/android/docs/reference/android/bluetooth/BluetoothClass.Device.Major.html

So what are these unknown devices with 7936 codes? I think this Java library needs to be updated for escooters, animals, and people. The World Economic Forum is talking about Internet of Bodies. We could have like: public static final int MOBILITY AND public static final int HUMAN_BODIES etc
