Looks like Android has BLE for 4.3+. I wonder if they could talk to each other? I knew whenever BLE got widespread support that what we were trying to do with TinCan would be much easier. I just didn't expect it to be supported this quickly. Last summer, all forums were expecting wider, stable support of BLE in maybe early 2015.
I just found out about iBeacons, pushing notifs, and use of BLE yesterday. I asked about Tin-Can but then I hit my knee really hard on the corner of my file cabinet and everyone laughed at me and the conversation went no where.
