Continuation of [this post](https://poal.co/s/QStorm/418589)... I ran a test of the post referenced in the link this morning at the local gym and what I saw under "Available Bluetooth Devices" was a large number of what appeared to be computer hardware addresses. The number was roughly equal to the number of people in the gym. Mixed in were 3 or 4 that were just the name of the phone or brand. Mine also appears that way but I am unvaccinated. Now it could just be that most people's phones are only broadcasting the phone's hardware address, for some odd reason. I'm not sure if that is normal behavior or not, I never noticed. Another test I have yet to run is whether they change periodically. Hardware addresses don't change periodically but these numbers allegedly do refresh every 8 hours or so, according to the post above. I have a friend that I know is vaccinated, I may try it the next time I see him. If you know someone who is vaccinated and has their phone nearby, you may want to check. Phone must be set to "visible" AFAIK.
