Screen beacon.png

Bluetooth LE Blue Puck, Blue Coin and Blue Slim beacons are disabled by default.
Configurations to these beacons are written through NFC.
To do this download Device Manager Mobile by Ela from Google Play Store to your Android-powered device.
Note! Android-powered device that is used for configuring Blue Puck/Coin sensors must support NFC read/write functionality.

Follow these instructions to easily configure Blue Puck/Coin/Slim Bluetooth LE Beacon:

  • Enable Bluetooth and NFC on your Android-powered device.
  • Launch Device Manager Mobile on your Android-powered device.
  • Select Configuration.
  • Place your Android-powered device on top of Blue Puck/Coin/Slim Beacon to scan it.
  • Click Enable to allow Blue Puck/Coin/Slim Beacon transmit advertising data.
  • We recommend to set Power to 4 to get the best possible distance.
  • Set TAG Format to iBeacon.
  • Set BLE Emit Period to 1 seconds to get best possible sensor detection.
  • Click Write button.
  • Place your Android-powered device on top of Blue Puck/Coin/Slim sensor to write configuration to it.

Once the configuration is written successfully, the Blue Puck/Coin/Slim Beacon will be enabled and use the settings configured in the APP.

NOTE! Make sure that Manufacturer data mode is Disabled, otherwise BLE Beacon will not be detected without additional changes in the device configuration.
NOTE! Every Beacon comes with default UUID, it could be changed via Device Manager Mobile app.

iBeacon data packet structure

Example of data parsing which comes with AVL ID 385
Two detected Beacons:

Data Part1 11
First Beacon:
iBeacon with RSSI flag2 21
UUID (Beacon #1) 3102030405060708090A0B0C0D0E0F10
Major 4545
Minor 010A
RSSI (Signal Strength: Signed 2's complement) BC (-68)
Second Beacon:
iBeacon with RSSI flag2 21
UUID (Beacon #2) 2102030405060708090A0B0C0D0E0F10
Major 020B
Minor 010A
RSSI (Signal Strength: Signed 2's complement) AD (-83)

1 Data part 11 - 1 Record out of 1 Beacon record. First half byte specifies current record, second half specifies how many there are in total. For example: 23 - second record out of three records (that means the server can expect 1 more records with Event I/O ID 385). If the data does not fit in a single data transfer, they are separated. Data Part is used to determine if more data will be coming from the device. Maximum value of the Data part is 33.

2 Flags:

21 iBeacon with RSSI
23 iBeacon with RSSI, Battery Voltage
27 iBeacon with RSSI, Battery Voltage, Temperature
01 Eddystone with RSSI
03 Eddystone with RSSI, Battery Voltage
07 Eddystone with RSSI, Battery Voltage, Temperature
