@nemik Congrats on the project. It looks really interesting so I bought one to play around with. I was going to use my Nexus 5 for testing but just realized it can't act in transmit mode. Do you have any recommendations for small beacons? The Estimotes beacons look big and the stickers don't look like they'd be very good for tracking people since they don't have a key ring. I've been looking at these. Think those would be good?
