BT Tag GUIDE 4.8
Proprietary and Confidential
The function is very useful when attaching the Tag to an object, such as hospital or technical equipment. By doing so,
one can track if any of these objects have been moved to another room or out of the building. Moreover, the Tag is
portable and can be carried by any employee which the company would like to keep track of. The device is
programmed to detect the normal walking speed which is 1.4m/s, therefore if a movement is below 1.4m/s, a higher
force will be required to wake up the BT Tag.
The second option for transmitting Beacon Events is by clicking the button on the Tag. The LED will blink 3 times in
green and as soon as the button is released, the Tag will send 4 TX burst.
3.2 Beacon types
The BT Tag supports 3 different types of beacons with the following corresponding parameters.
• iBeacon – UUID, Major, Minor
• AltBeacon – Beacon ID
• Eddystone-UID – Namespace, Instance ID
Each BT Tag can support only one beacon format, which can be chosen by the customer itself. As mentioned before,
the broadcast of the beacon is limited to 4 times (4 TX) within 150ms in order to save the battery life and to ensure
that the receiver will catch the Beacon Event. In case of pressing the button while movement is detected, the device
will ignore the new action while the previous one is still on.
3.3 Beacon data transmission
The data transmitted by the BT Tag follows the format specified in the Bluetooth Core Specification. The broadcasted
data that the user can see on the alarm server depends on the type of beacon and displays the following information:
• For iBeacon – Proximity UUID, Major, Minor and Signal Power (RSSI measured at 1m)
• For AltBeacon – Beacon ID, 1 byte defined by the manufacturer and Signal Power (RSSI measured at
1m)
• For Eddystone-UID – Namespace, Instance ID and Signal Power (RSSI measured at 0m)
The rest of the data which is being transmitted is filtered away by RTX and therefore cannot be visible (See Appendix
A for more details). The Signal Power is around -3dBm for all type of beacons and it’s measured either at 1m (for
iBeacon and AltBeacon) or 0m (for Eddystone).
4. Connect to the Location gateway/Send beacons
The RTX8210/RTX8212 TAG does not need any configuration in order to connect and transmit beacons to the
gateway. After activating the TAG, simply pass by an RTX8200 Location gateway and leave the TAG still with no
movement for 30 sec. The gateway will detect the beacon being transmitted from the TAG and depending on your
server configuration, you will be able to see the output.
If you wish to test the connection, you can short press the button on the device and a Beacon Event will be sent to the
Location gateway.
An example can be seen on the screenshot below. Please note that depending on your server configuration the output
may be different from the one mentioned in this manual.
The data received and displayed from the BT Tag is the BT MAC adress, beacon type, content of the beacon and signal
power. The rest of the data output depends on your alarm server and RTX8200 configuration.
