BLE Beacon function
The BLE Beacon function detects Beacon devices within communication range using the
Advertise function for GAP (General Access Profile), not the function described in the BLE
profile.
When the BT-2000 is within the Bluetooth communication area for a Beacon device, the
Beacon device is detected using Advertise data being broadcast by the Beacon device (note 1),
and then calculates the distance from the Beacon device using the strength of the radio waves.
Note 1)
If the Beacon device supports the iBeacon standards, the device can determine Immediate/Near/Far from the
RSSI value. If the device does not support the iBeacon standards, the distance need to be calculated from the
RSSI value.
