AIA ad in the lobby of AIA, no sound. All about Net Zero by 2050, app guidance or tracking. Sounds like a carbon tracker app. One billion, longer healthier lives by 2030. I wonder if this is one billion of the world's population #AIAOneBillion

This is an excerpt from the documentary Died Suddenly. Where Bill Gates said he will reduce the world's population by 10% through vaccination. Politifact claims to have debunked this. View the original clip from his Ted Talk from 2010. Forward to 04:20 and decide whether it has been debunked

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

Mystery bluetooth MAC addresses. Recorded using the Samsung built-in screen recorder, Android 11. The first part of the clip was done using a downloaded app. The second part was using the built-in Bluetooth app.

The downloaded app is called
Bluetooth Finder & Scanner by Little Angel. The scan was made in a bus of about 10-15 people while over Harbour Bridge which is 2km. The app gives you 3 lines of info. First line is the device name. The second is the device type. The third is the MAC address.
Below the signal strength was my distance from the device.

Most of the devices had no name and no category. Let me know if you think you know what these unknown MAC addresses are.

MACs ought to have a vendor assigned to them. There are online MAC checkers which tell you which vendor they belong to.
You can pause the video and try entering them to an online checker. You only need to enter the first six characters ignoring the ":" and it's not case sensitive

Some devices generate random MACs but they give out at least a device name. Our Nikon DSLR doesn't have a fixed MAC. Using random MACs mean not paying licensing fees to IEEE, which save the vendor money.

In the built-in Bluetooth app, at the second part of the clip, you will see 2 devices that start with 13/VAL-TX. These belong to the bus and are on other buses as well. They are there whenever I do a scan.

If you're using Android 8, you will see the mystery MACs but you won't see their distance from you.

I've explained in detail my process and what I know. I've been scanning for some months and my scans give consistent results and I also use 5 other Bluetooth scanner apps. The apps detect devices up to 31m away so I could also be seeing devices from nearby cars.

I've been using Bluetooth for about 8 years and I don't remember seeing mystery MACs in the list. Any theories or ideas?

This is a screen recording of the available mystery bluetooth devices in a bus. There were between 5-9 people at the time. I saw 16 devices. You will also see the distances to the device from where I was. This was using a bluetooth tracer app. Then I switched to the built-in bluetooth finder in the settings. In there I only saw the two bluetooth devices which were in the bus - 13/VAL-TX... Why is that? Why are there mystery MAC Addresses. No device name and no vendor. If I do an online check on these MACs, they aren't assigned to any vendor. Does anyone have an explanation? The OS version was Android 11. If you were to use an earlier version of Android, you will also see these mystery MACs in the built-in bluetooth scanner. I have done more testing and with other bluetooth apps and they give similar results.
