Beacons use the newer Bluetooth 4.0/'low energy' specification so they're not like old Bluetooth devices that are constantly connected. It's up to each beacon to decide how often it broadcasts, how powerfully, etc. Check out BLE SoC's like the Nordic nRF51822 for examples of hardware that could turn into a beacon without a ton of work. |
