Hi - Are you using the kit project as it is or did you make any modifications on that?
Sorry for the delayed reply. I'm using the kit project as is, no modifications. I checked two ways, one using my Samsung note4 and the other using the BLE-USB bridge dongle that comes with the kit. In the second case I see that the blue LED on the dongle stops blinking as I move the BLE beacon away to about 30ft or so.
