BT scanning in events/festivals




Many 4/5G radio modems ... some BT connectable etc...




Sometimes one can find walkie-talkies with BT on ... connect is perhaps possible if device user happens to accept connection ...


Probably blood pressure monitor (first aid place or something like that...)


 

Trackers, earbuds and unknown devices (staff? security staff? high level security staff?)
