BT Tag Double adhesive tape Battery Damage Inspection:
The following are the recommended procedure for you to use for inspection:
1. Examine all relevant components for damage. 2. Make a defective on arrival DOA report or RMA to the operator. Do not move the shipping carton until the operator has examined it. If possible, send pictures of the damage. The operator/regional representative will initiate the necessary procedure to process this RMA. They will guide the network administrator on how to return the damaged package if necessary. If no damage is found, then unwrap all the components and dispose of empty package/carton(s) in accordance with country specific environmental regulations. 3. 2.2 Product overview This section aims to give you an overview of the product itself. The following sections will guide you through the process of opening the device, changing the battery and details about mounting the Tag. The image below shows how the BT Tag looks like from the front and back side BT Tag GUIDE 4.8 Proprietary and Confidential On the front side there is a sticker with a Data matrix barcode and the MAC address of the device. If scanned, the barcode gives information about the MAC address of the device, as seen on the label. The grey spot next to the sticker marks the button of the BT TAG, which serves for activating the device and sending beacons (See chapter 2.4.1 Button features for more details). 2.2.1 How to open the device The main purpose for opening the device is for changing the battery. Please follow the steps below in order to open the BT TAG.
-
Step 1: Place your fingernail on the slot and pull out the battery cover as shown on the pictures below
-
Step 2: Separate the 2 covers and open the device BT Tag GUIDE 4.8 Proprietary and Confidential
-
Step 3: After opening the BT Tag, the following should be visible to the user On the inner side of the RTX8210/RTX8212 there is information about the products certificates, beacon and battery type, and more. There is a plastic plate under the battery which should be removed in order to activate the battery
(see the picture below). Remove the battery and take out the plastic Place back the battery BT Tag GUIDE 4.8 Proprietary and Confidential 2.2.2 Mounting One of the main purposes of the BT Tag is to track objects, meaning that the Tag can be attached to them. Installing the device correctly will make a difference in the performance. The following is a general guideline on how to position the device for better functionality. The tag transmits approximately -3dBm of power and has a radiation pattern as shown on the image below. In order to achieve the best performance, the user should avoid surrounding the device with metal surfaces and mount the Tag in accordance to the receiver. The reason thereof is the radiation patterns which need to be considered in order to get a strong transmit signal to reach the destination The illustration below shows an example of a good mounting solution for the Tag. The positioning is consistent with the one of the receiver, in this case RTX8200 (For mounting guidelines of the RTX8200, please refer to the RTX8200 Location Gateway manual). Taking into consideration that the signal of the Tag is spread around it, in this case it will be necessary to attach it in a vertical position, so that the receiver can catch the Beacon Events BT Tag GUIDE 4.8 Proprietary and Confidential On the contrary, a bad mounting solution in the same scenario would be placing the Tag in a horizontal way under the bed, as shown on the second illustration. By doing so, the signal strength will not be as strong and will be partly blocked by the bed. To make it easier and accessible for the user to attach the BT Tag to objects, RTX has added 2 extras. The device comes with a double-sided adhesive tape in the box that allows the user to attach it to any other object than ferromagnetic parts. Besides the tape, the BT Tag has two built-in magnets which can be seen on the left and right side of the cover around the battery. The magnets allow the user to attach it to metal objects and track them if movement is detected. The pull force is around 40g (see the image below). BT Tag GUIDE 4.8 Proprietary and Confidential Despite the magnets, the user should avoid mounting the RTX8210/RTX8212 to a metal surface and instead use the tape to stick it to another available exterior, if possible. An example is shown on the Image 1 where the Tag is positioned on the wooden material, instead of the metal frame of the bed. 2.3 Power to device The RTX8210/RTX8212 uses CR2016 in order to have power and comes with the battery already in the device. Open the BT TAG as shown in the previous chapter and activate the battery by removing the plastic plate (See chapter 2.2.1 How to open the device for more details). BT TAG Battery CR2016 2.3.1 Battery operation Thanks to the low power consumption design the BT Tag can operate up to 1 year using the CR2016 battery. The life of the battery depends on the user scenario and how much the device is used. Moreover, the user should have in mind that the device consumes more power when the button is pressed due to the blinking LED. For more technical details on the battery consumption, please refer to Appendix B. The functionality of the device is driven by the following features:
Low battery warning when the battery level drops to the configured threshold (2V) or below, the LED will start blinking in red every 20 sec and the device will disable all functions. This means that no beacons will be sent, the button and the movement detection will be disabled. The battery is not chargeable; therefore, as soon as the battery is replaced with a new one, the functions will resume back to normal. We advise you to monitor regularly the battery level in order to avoid power loss. Power save mode when no movement is detected, the BT Tag will go to power save mode. It will report every 10 seconds during the movement (please see chapter 3.1 Functionality for more details) 2.4 Power on device After removing the plastic plate and adding the battery, assemble the Tag and press for 3 sec the button until a green light indicator is shown (see the picture below). The green light indicates that the BT TAG is now on and it is ready to send beacons. After powering the device, it goes to sleep in order to save power. BT Tag GUIDE 4.8 Proprietary and Confidential 2.4.1 Button features The BT Tag has one physical button which handles the base function of the Tag, such as activating the device and sending beacons. Depending on the way the button is pressed, one of the cases will apply:
No press when the button is not pressed and no movement is detected, the Tag is in sleep mode in order to save power. Short press serves for device activation, meaning that when the button is pressed for at least 100ms and less than 3000ms, you will wake up the Tag and send a Beacon Event signal Long press the long press serves for device activation, meaning that if the button is pressed and hold for 3000ms, the device will be powered up 2.4.2 LED features The BT Tag has LED which can blink in red or green and gives various information about the device. Please see below the meaning of each color:
Red depending on the status, the red LED will appear in case of:
o Low battery LED blinks 3 times every 20 seconds o Accelerometer no response LED blinks in red 10 times Green depending on the status, the green LED will appear in case of:
o Button is pressed to send a beacon LED blinks 3 times o Power on device LED blinks once for 2 seconds No color Tag is in sleep mode to save power 3. Detailed operation The following chapter presents the technical details of the functionality and operation of the Tag. The supported beacon types and their transmission is included in the following subchapters. 3.1 Functionality Once the Tag is powered on, it is ready to send beacons. There are two possible options for sending a beacon:
Movement detection Pressing the button The first and main option is implemented in order to save power on the device. The movement detection feature is controlled by the accelerometer which determines the movement and duration. This means that as soon as a movement is detected, the Tag wakes up from sleep mode and immediately sends a Beacon Event. The Beacon Event consists of 4 TX burst which are sent every 10 seconds during movement detection. Out of all 4 broadcasts, only one will be detected and displayed on the UI. The transmission will continue until no movement is detected for 30s, meaning that if the item/person stops at one place for more than 30s, the Tag will send a last Beacon Event and stop transmitting until the next movement has started. 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 its 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.

In order to deliver high quality services and products, RTX has made a calculation file which enables the user to measure the estimated battery life depending on the scenario. The file allows the user to input the expected average motion pattern of the device. This means that the user can specify the expected hours that the Tag will be in motion and the number of times the button will be pressed. Based on this data, the code will calculate the estimated battery life in days, months and years. A few example scenarios are presented in the image below. BT Tag GUIDE 4.8 Proprietary and Confidential As you can notice from the calculations above, the more the button is pressed, the more power it is consuming from the battery. As mentioned before, this is due to the LED that blinks every time the button is pressed. Moreover, the Transmit interval in motion is fixed and cannot be changed. It is present in the table, because it is used for the calculations. For more details about the calculation file, please contact RTX support. BT Tag GUIDE 4.8 Proprietary and Confidential
