A beacon will continuous broadcast signals to let other bluetooth devices know the presence of it. And I’ve always wanted to have a bluetooth beacon to track my keys since I’ve already forgot to bring them like 10 times last year. And I happendly got a HM13 dual module. So I think I could turn it into a simple iBeacon to let me know if I forgot to bring my keys. But when I finished it, I realized I wouldn’t keep checking my phones. Thus, I decided to make a continuos beacon scanner with Raspberry Pi as a bluetooth gateway. So I can trigger it to email me or text me to remind me of my keys.
And here is how to make it happen.
