I want to track people (carrying mobile devices) on a pedestrian street using the two “control points” A and B.
I plan to place mobile devices or netbooks with Android / IOS or Linux at each checkpoint and register an identifier so that I can find out how many of them passed from A to B. I know that I can open other people's devices using bluetooth, but this can i do using wifi? I'm thinking of turning my devices into Wi-Fi hotspots. People, of course, will not connect to the access point, just passing by.
So my question is: can this be done on the mentioned platforms? It is very important that I can tell if the same person went through both A and B by registering a “device identifier”, that is, a MAC address.
