I'm using the "NextGen Bluetooth RSSI Analyzer" on my phone

It easily detects if someone has the MAC address emitting nano-tech in them, but you have to get them away from other humans by about 100 feet to test them - passing it on - help?

I'm using the "NextGen Bluetooth RSSI Analyzer" on my phone (no longer available from the Play store of course). It easily detects if someone has the MAC address emitting nano-tech in them, but you have to get them away from other humans by about 100 feet to test them. Also there's ways to set your Android or Apple phones to detect "unknown" Bluetooth MAC addresses without having a third party app. You have to put the phone in developer mode and change some Bluetooth settings. I generally don't mention anything about the MAC address phenomenon to anyone "vaccinated". What's the point? It's done, they're done.

Don't know if these are the same thing - Google: NextGen Bluetooth RSSI Analyzer to find and use them
