This is basically what we're trying to re-create. Would this not be a bluetooth proximity scanner?

So if i wanted to implement technology much like this piece of hardware: https://www.thetileapp.com/en-gb/

That also reported the distance of the bluetooth beacon & signaled the app if the beacon moved x meters away. What would I need to make this happen?

Thank you for your help

haha it's intended to be used by parents or those in charge of vulnerable persons.
If it was maximum 3 bracelets per app/receiver would this be possible and bypass the need to scan and report more than 6 MAC Addresses?

Hi,

There's a big theme park where I live & I'm thinking of implementing a bluetooth proximity sensor as a bracelet & app.
This will allow users to connect their bracelet to their phone and keep track of whoever is wearing the bracelet.
I'm really not very well versed in this technology so any help in layman's terms will be greatly appreciated.

Many thanks,
Daniel
