I am currently in the middle of my thesis project and a small part of this is creating a bluetooth tag access control. I just received my BLE Shield (http://redbearlab.com/bleshield/) and would really find it helpful if someone could link me to code that will scan for bluetooth devices and get their id's. (A sketch would be fine too)
Hey!! I am working on this too without success yet!
Did you manage to find a solution to scan and communicate with BLE devices around?
I can communicated with other iOS apps if I were to set my BLE to peripheral. But I have no idea on how to scan if I set it as central. I am using a BLUNO by the way.
It cannot scan other BLE. It can only communicate and connect to another BLE. Point to point connection. It does not support multi-connection at any one point of time.
