About the Accuware Smart Tags

The Accuware Smart Tags are mobile devices designed for tracking remotely, indoors movement of people and assets thanks to the usage of the Accuware Wearabouts engine.

A device’s location is determined using one or more of the following sources of information:

  • the Wi-Fi 2.4 GHz legacy/b/g/n.

When active, a Smart Tag takes periodic snapshots the radio signals by making scans in real-time of the environment at the device’s current location and sends the collected data to the Accuware server. The Accuware server estimates the Smart Tag location by pattern-matching the radio signals sensed in real-time against the WiFi access points available inside the Accuware databases of Wi-Fi signals created for that specific location (during the fingerprinting phase).

The location of all Smart Tags is made available as a pair of latitude and longitude (WGS84 format) and can be:

  • visualized inside the Accuware dashboard.
  • integrated inside any Web or Mobile application capable of using RESTful API.

Features

These are the key features of the Smart Tags:

  • Real-time indoor location – the highest update frequency is 5 seconds (this update frequency can not be increased).
  • Low battery usage – thanks to the motion detection parameters.
  • Minimum data usage – thanks to the motion detection parameters.
  • Wireless configuration – the tracking parameters are set using the Accuware dashboard and sent over-the-air (OTA) to the Smart Tag from the Accuware server.

External sensors: it is possible to add some external sensors to the Smart Tags (e.g. temperature, heart rate, fall detection). For more details about these features, please submit a ticket request at this link.

Attach the Accuware Smart tags to assets or people: you can find some solutions inside this page.

Functions

  • Button: there is one button at the center of the tag. This is the button used to control the tag.
  • USB port: for battery recharge. Connect to a USB charger or a computer USB port using a micro USB cable cable (not included in the package).
  • Battery: the Smart Tags have an internal battery that must be periodically recharged. Time between charges ranges from a few days to a few weeks, depending on the Tracking Parameters set using the Accuware dashboard. IMPORTANT:
    • A full charge cycle takes about 2 hours.
    • To increase the battery lifetime we suggest to keep the battery charge above 50%. Bad charging and depletion management can dramatically decrease the life time and capacity of the battery.
    • The battery depletion of lithium batteries is not linear. This means that the, as an example, it can take 3 hours for the battery to deplete from 60% to 30% and only 1 hour to deplete from 30% to 0%.
    • While under charge (regardless the amount of charge of the battery) the Accuware dashboard shows the message: ” charging”.
  • LED information:
    • LED1
      • ON: when it is under recharge; LED1 turns off when charging is complete.
    • LED2
      • blinks every time the Smart Tag is trying to connect to the WiFi network in order to communicate with the Accuware server. The Smart Tag tries to connect to the WiFi network when:
        • the button is pressed.
        • the Smart Tag is in movement (the frequency of the blinks is function of the Moving parameter).
        • the Smart Tag is stationary (the frequency of the blinks is function of the Stationary parameter).
      • blink alternately with LED3 when the tag is turning OFF.
      • blinking together with LED3 when the Smart Tag is reset to factory defaults.
    • LED3
      • blinks while the Smart Tag is communicating with the Accuware server.
      • blinks alternately with LED2 when the tag is turning OFF.
      • blinks together with LED2 when the Smart Tag is reset to factory defaults.

Safety information

  • Please do not use the Smart Tags in an environment with hazardous gas.
  • Please keep the Smart Tags away from water or rain.

Step 0 – Reset your Smart Tag

The very first thing you need to do is to reset your Smart Tag to factory default and put it under charge following these steps:

  1. Turn ON your Smart Tag by following these steps:
    1. Shake the Smart Tag and at the same time start pressing the button. LED2 will start blinking. Keep the button pressed and keep shaking the Smart Tag until LED2 stays ON.
    2. Once LED2 stays ON, stop pressing the button (LED2 will turn OFF).
    3. The Smart Tag is now active.
  2. Press the button and keep it pressed for about 10 seconds. LED3 and LED2 will start blinking alternatively. Keep the button pressed until LED3 and LED2 blink together. At this point you can stop pressing the button.
  3. Your Smart Tag is now reset to the factory configuration and is turned OFF.
  4. Connect the Smart Tag to a USB charger (or a computer USB port) using a USB micro cable. Leave it under charge for at least 1 hour or until the charging is complete and LED1 turns off.

TurnON_FactoryReset

Step 1 – Verify the prerequisites

These prerequisites MUST be met by all the Smart Tags that you want to use with the Wearabouts engine:

  • the Smart Tags have a valid Wi-Fi Internet connection in the entire area in which the Smart Tags will be used. This permanent WiFi network is necessary to upload to the Accuware server the radio signal sensed in real-time. These are the network requirements that MUST be met by this network (and also by the temporary WiFi network used by the Smart Tags to download the configuration file as explained in the next paragraphs):
    • Accessible domain: navimote2.navizon.com – this is the address where the Smart Tags sends the radio signals sensed in real-time.
    • Ports (opened outbound): 53/tcp (DNS), 8082/tcp (HTTP).
    • Wi-Fi 2.4 GHz legacy/b/g/n – make sure that the network is not set to work ONLY with the “n” standard.
    • Wi-Fi Bandwidth: 20 MHz
    • Wi-Fi splash page/captive portals: there MUST not be a splash page/captive portal. If there is a splash page/captive portal then you should ask to the ​network administrator if it is possible to add an exception in order to disable the splash page for all those devices with a MAC address that starts with 54:FB:58:XX​:XX:XX​ (the Smart Tags)​.
    • Wi-Fi security: no password/WEP40/WEP104/WPA-PSK/WPA2-PSK). If the security is WPA-Enterprise then you should ask to the ​network administrator if it is possible to add an exception in order to enable a different authentication method for all those devices with a MAC address that starts with 54:FB:58:XX​:XX:XX​ (the Smart Tags)​.
    • Wi-Fi SSID visibility: the SSID must be visible. The Smart Tags can’t connect to hidden SSIDs.
  • the Smart Tags are fully charged.
  • a special user called navimote@navizon.com is inside the users of your Accuware site. This can be checked easily following these steps:
    1. Access the Accuware dashboard at at this link.
    2. Click on General > Accounts
    3. Verify that navimote@navizon.com is inside the Registered Accounts table with “Read-Write” Access.

Proxies:  our Smart Tags can’t works with proxies/firewall in the middle. For this reason you need to ask to the IT department your company to add an exception to the proxy to allow the MAC addresses of the Smart Tags to connect without credentials to these domains listed above using the ports listed above.

Step 2 – Choose the right location source for your project

When active, the Accuware Wearabouts computes multiple locations using the following location sources:

  • Indoors – the Accuware database of fingerprints of Wi-Fi signals available if an indoor fingerprinting has been performed.
  • Global – the Navizon global database of Wi-Fi signals throughout the world.

Then, once multiple locations have been computed, the Wearabouts engine chooses the location with:

  • the most recent time-stamp. The time-stamp related to one location is better then all the others if it is at least 15 seconds greater than the time-stamps of all the other locations).
  • or the higher accuracy (smaller radius of confidence) when there are multiple locations with time-stamps that do not differ for more than 15 seconds.

Despite this, having multiple location sources active, could have a negative effect on the accuracy when some of the location sources are not of interest. For this reason, before proceeding, we invite you to submit a support request using this form and let us know which location sources you don’t plan to use.

Example

  • if your project is to track the location of doctors and staff inside an hospital (where you have collected the fingerprints), it is not useful to leave the Global location source active. Why? Because this additional location sources will cause jumps outside the hospital if/when the Wearabouts engine won’t be able to compute the indoor location.

Step 3 – Register the Smart Tag to the Accuware server

To make the Accuware server aware of your Smart Tag you need to register it to your Accuware site using the Accuware dashboard following these easy steps:

  • Access the Accuware dashboard at at this link and follow the instructions on the login screen. Please supply the credentials contained in the email from Accuware Activation email and press the Login to Dashboard button.
  • Click on Wearabouts > Devices. This section shows the list of all the devices registered within the site. By using the buttons on the right side of the table it’s possible to edit the information associated with a device (Name, Description), delete a specific device, or configure a specific device (device-specific parameters). If you get the Error message “Error 400 – Bad Request”, it means that your Accuware site is not enabled for the usage of Wearabouts (please submit a ticket request at this link).
  • Press the Add Device button, and type the MAC address that is shown on the back of the Smart Tag (it starts with 54FB58 and contains a total of 12 characters).
  • (OPTIONAL) insert a Name and a Description
  • Click on the Save button. If you get the Error message “MAC ‘WXXXXXXXXX’ is already associated with another site, you need to remove the ID of that device from an already existing site. At present, devices can not be associated to multiple sites.
  • Your device will appear in the Registered Devices table.

Step 4 – Configure the Smart Tags

To be configured, each one of the Smart Tags needs to download their configuration file from the Accuware server by connecting to a temporary WiFi network with some specific parameters. The configuration file that needs to be downloaded by the Smart Tags includes the parameters of the permanent WiFi network that will be used by the Smart Tags to communicate with the Accuware server during their normal usage.

Here is the steps you need to perform to allow the Smart Tag to download the configuration file:

  • Create and activate a temporary WiFi network with these parameters:
    • SSID (case sensitive): Navizon_CFG
    • Password (case sensitive): Navizon123 
    • Security: WPA/WPA2
  • Once the temporary WiFi network is active please access the Accuware dashboard at at this link and follow the instructions on the login screen. Please supply the credentials contained in the email from Accuware Activation email and press the Login to Dashboard button.
  • Click on Wearabouts > Configuration.
  • From the Show Config for menu please select Smart Tags
    • SSID: enter the name of the permanent WiFi network that will be permanently used by the Smart Tags.
    • Security Mode: choose the security mode of the permanent WiFi network that will be used by the Smart Tags.
    • Passphrase: choose the password of the permanent WiFi network that will be used by the Smart Tags. You can view your Passphrase in clear text, by pressing the icon on the right.
  • Press the Save button.

PLEASE READ:

  • if you are not allowed to create a temporary WiFi network in your corporate environment, then you should configure your tags using the hotspot/tethering functions of your smartphone or tablet. This smartphone/tablet MUST have a valid cellular data connection.
    • Android devices: Settings > Wireless and networks > Portable Wi-Fi Hotspot > Configure
    • Apple devices: the availability of the Personal Hotspot feature depends on the Cellular Provider.
  • don’t forget that the SSID and Passphrase are case sensitive fields. Saving wrong details will prevent the Smart Tag from connecting to your permanent WiFi network and you will have to Factory Reset your Smart Tags following Step 0.

Step 5 – Turn ON your Smart Tag

  • Turn ON your Smart Tag by following these steps:
    1. Shake the Smart Tags and at the same time start pressing the button until LED2 stays ON (it must stay ON and NOT blink!).
    2. Once LED2 stays ON, stop pressing the button (LED2 will turn OFF).
    3. The Smart Tag is now active.
  • The Smart Tag will connect for few seconds to the temporary WiFi network to download the configuration file. Please wait for about 1 minute without turning OFF the Smart Tag. Once done the Smart Tag will automatically connect to the permanent WiFi network set inside the Accuware dashboard.

TurnON

Check if the configuration file has been downloaded by the Smart Tag: this can be easily checked by looking for the list of devices connected to your temporary WiFi network (or by asking to the network administrator to do so).

Step 6 – Track your Smart Tags using the Accuware dashboard

To get the fresh location of the Smart Tag you need to follow these steps:

  • Click on Wearabouts > Map
  • Scroll down the page until the Devices table
  • Click on the blue icon located inside the Position column next to the Smart Tag that you want to track.
  • Once clicked, the Google Map view will automatically move to the last location of the Smart Tag that will be represented as a:
    • YELLOW dot: if the device has been seen active in the past 15 minutes.
    • GREY dot: if the device has been seen active more than 15 minutes ago.
  • By clicking on the dot you will be able to see this information:
    • Name – the optional name assigned under the Wearabouts > Devices section.
    • Desc – the optional description assigned under the Wearabouts > Devices section.
    • Mac – the device unique ID generated by the Wearabouts App.
    • Level ID – the level on which the device is located.
    • Position – the location computed by the Accuware server along with the level ID.
    • Source: the source of the location (Indoors, Global):
      • Indoors – this location is computed by using the Accuware database of fingerprints of Wi-Fi signals available if an indoor fingerprinting has been performed.
      • Global – this location is computed by using the Navizon global database of Wi-Fi signals throughout the world.
    • Battery – the battery level detected along with a label for the charging status. IMPORTANT:
      • A full charge cycle takes about 2 hours.
      • To increase the battery lifetime we suggest to keep the battery charge above 50%.
      • The battery depletion of lithium batteries is not linear. This means that the, as an example, it can take 3 hours for the battery to deplete from 60% to 30% and only 1 hour to deplete from 30% to 0%.
      • While under charge (regardless the amount of charge of the battery) the Accuware dashboard shows the message: “charging”.
    • Last Seen: the amount of time passed since the device has been seen.
    • ACTIONS – this column contains 2 buttons:
      • Radius of confidence: this button can be used to visualize the radius of confidence.
      • Follow on the map: this button can be used to center the location on a specific device and follow its movements on the map.

If you are able to see the location of your Smart Tag in real-time then you can disable the temporary WiFi network.

If you are not able to see the location of your Smart Tag and you performed Step 0 and you met the prerequisites at Step 1, then it could be that you entered wrong details for your permanent WiFi network. In this case you need to:

  1. Perform a Factory Reset of the Smart Tag (as described in Step 0) in order to allow it to connect to the temporary WiFi network and download the NEW configuration file that contains the correct details of the permanent WiFi network.
  2. Repeat the steps starting from Step 4 – Configure the Smart Tags.

Troubleshooting: if you encounter any issue related to the accuracy, please look at this page where you will find all the help you are looking for.

Move the Smart Tags into a new location: if the Smart Tags have been already used successfully inside a location and you want to use them inside a NEW location please read this support page.

Turn OFF a Smart Tag

If you want to Turn OFF a Smart Tag you have to follow these steps:

  1. Start pressing the button and when LED2 and LED3 will start blinking alternatively stop pressing the button. Don’t keep the button pressed for more than this otherwise the Smart Tag will be reset to factory default!
  2. LED2 and LED3 will turn OFF and the Smart Tag is now OFF.

TurnOFF

Tracking parameters

When your Accuware site is enabled for the usage of Wearabouts, by the Accuware Support team, the following JSON with site-wide parameters is associated to your Accuware site:

This means that all the Smart Tags registered to the Accuware server (using the Accuware dashboard as described in a previous section) will inherit these site-wide parameters. This is true unless the site-wide parameters are overwritten by device-specific parameters that can be optionally associated to specific Smart Tags.

The site-wide parameters and the device-specific parameters are downloaded by the Smart Tags automatically when they connect to the temporary WiFi network (as described above).

Once the parameters have been downloaded by the Smart Tag, the Smart Tag starts to perform scans of the environment at the current location and it sends the collected data to the Accuware server.

Site-wide parameters

To configure (Inspect, Save, Reset) the parameters for all the devices registered within the site (site-wide parameters):

  • Click on Wearabouts > Configuration

Here is what is shown in this page:

  • Last update: the amount of time passed since the site-wide parameters have been saved.
  • Show config for: a top-down menu that allows to show the parameters for a specific type of device (Android devices/iOS devices/Smart Tags)
  • For all the info about the parameters see the section Parameters paragraph below.
  • Controls: you can Inspect (view) the JSON with the parameters, Save the parameters, Reset the parameters to their default.

Device-specific parameters

To configure (Inspect, Save, Reset) the parameters for a specific device (device-specific parameters):

  • Click on Wearabouts > Devices
  • Click the Config icon with a gear located inside the Action column

Here is what is shown in this page:

  • Associated: the amount of time passed since the device has been registered.
  • Configured: the amount of time passed since a configuration has been sent to the device.
  • Show config for: show the type of device automatically detected. It can’t be changed.
  • For all the info about the parameters see the section Parameters paragraph below.
  • Controls: you can Inspect (view) the JSON with the parameters, Save the parameters, Reset the parameters ​to the site-wide parameters (which can be different from the the defaults).

Parameters

Here is a description of all the parameters that can be configured at site level (site-wide parameters) or at device level (device-specific parameters)

Wi-Fi
  • SSID: the name of the permanent WiFi network that will be used by the Smart Tags.
  • Security Mode [default = wpa/wpa2]: either “open”, “wep40”, “wep104”, “wpa/wpa2”.
  • Passphrase: is the plain text passphrase of the  permanent WiFi network for all security modes, except “open”. Your plain text passphrase is server side encrypted (as like the other configuration parameters), stored there and can be retrieved later on for revision or correction.
  • Channel List [default = 0]: comma separated list of WiFi channels to be scanned (e.g: 1, 6, 11). If first element is 0, ALL channels are scanned.
  • Security Domain [default = ETSI]: either ETSI, FCC, JS
Position Updates Frequency
  • Moving [default = 30 seconds]: seconds between position updates when the device is moving. This value affects the battery life.
    • If Moving is set to X seconds (with X different from 0), the device wakes up every X seconds and checks the accelerometer for movement. If there is a movement a scan of the radio signals is initiated and the result is uploaded to the Wearabouts server (where the location is computed).
    • If Moving is set to 0, the periodic check of the accelerometer is disabled and there won’t be updates of the locations based on the Stationary parameter. In this scenario the only way to force the device to update its location is to push the button on the device.
  • Stationary [default = 3600 seconds]: seconds between position updates when the device is stationary. This value affects the battery life.
    • If Stationary is set to X seconds (with X different from 0), the device will update its location every X seconds while stationary.
    • If Stationary is set to 0, enforced scans of the radio signals are not performed (and the location is updated only according to the Moving parameteor when the panic button is pressed).
Advanced settings
  • Stationary Info Threshold [default = 30 seconds]: seconds with no movements after which a Smart Tag is considered stationary.
  • Alarm discard [default = 7200]: seconds to retain the panic button alarm when the Smart Tags is not able to communicate with the server (e.g. connectivity issues).
  • Buzzer [default = Enabled]: audio feedback when the panic button is pressed.
  • Connection Timeout [default = 20]: timeout waiting for server response (the value needs to be multiplied by 100 milliseconds).
  • Info Without Config [default = 0]: how many uploads a device does, until it recognizes a new configuration. E.g. a value of 5 means that the device is requesting a new configuration only with every six upload. By that this parameter controls the speed, by which a device reacts on configuration changes. The server will only send back a configuration, if there was a change.
  • Panic Button [default = 20]: seconds between panic button press and alarm (the value needs to be multiplied by 10 milliseconds).
  • Shutdown [default = 4]: how many seconds the panic button need to be pressed in order to turn off the Smart Tag (0 means immediately).
  • WiFi [locked ON]: controls the usage of the Wi-Fi access points on 2.4 GHz and 5 GHz for the computation of the indoor locations.
