Mobilaris Companion WiFi
The Mobilaris Companion WiFi, PN 3049900039, is a rechargeable Wifi personal and vehicle tracking tag developed for mining and tunneling applications. The tag can provide positioning using both WiFi Access Points (AP) and Bluetooth Low Energy (BLE) beacons. The battery is rechargeable, either via standard USB-C charger or a separately sold charging rack. It has an accelerometer for battery saving features and movement detection. A multi-purpose push button can be used for Emergency Acknowledge or other custom features. The tag can be provisioned to personnel using built-in NFC. Emergency notification to user with a vibration motor, strong LED and buzzer.

Functionality
In operation mode, the tag is reporting AP/BLE readings by scanning WIFI APs and BLE beacons to the configured broker. Scan duration and interval for BLE is configurable and by default one second and five seconds respectively. The report interval is by default 10 seconds but can be configured to any value above three seconds. In between the reporting of AP/BLE readings, the tag is sleeping and will wake up on network activity or pressed button. Accelerometer is used to detect any movement and in the absence of movement, the tag will decrease the report interval to 10 minutes.

LEDs
Short description on how the LED is used follows here:

A tag connected to a charger has yellow led on when charging and green when fully charged.
A tag that is active (movement detected) and connected to the network will blink short green when waking up from sleep.
A disconnected tag blink short red on wakeup
A tag that is connected to the network and inactive (no movement detected) will blink short yellow on wakeup
When successfully connected to network, the tag is blinking green four times
When starting an over the air update (OTA), a yellow led is turned on and blinks green after successful OTA
If BLE firmware is downloaded, the blue led turn on during installation of firmware and turn green on successful or red on failure

OTA updates
The tag performs OTA updates after a factory reset or on a periodic interval, default is 25 hours. During the OTA, the tag requests the backend if there is any new configuration, new files or new firmware to be downloaded. If yes, the files are downloaded and saved/installed, if no, the tag go back to normal operation mode To add or change profile for a tag, go to the Profile tab in the admin pages, see section 3.1.2. And add/change profile, remember to assign the profile to the tag by specifying MAC-address. During a OTA, no other tasks are performed such as BLE or AP scanning/reporting. Time spent on OTA depends on resources in backend available for download, approximated time spent is listed below

No update/profile: ~a few seconds
WIFI Software/certificates: Up to 5 seconds
BLE Software: ~1 min including installation of software onto the device

When updating BLE software over OTA, the USB must be disconnected.

Emergency
Emergency mode is by default enabled on the tag. When an emergency is triggered in Mobilaris Emergency Support, the tag receives a notification. The tag then sends a delivery message notifying that the emergency message has been received to the tag. Then the tag starts a vibration, a buzzer and a stronger white LED, to notify the user that there is an ongoing emergency. By pressing the button, the user sends an acknowledge message to the emergency application and the vibration/buzzer and white LED stops after the acknowledge message has been sent.

Alarm
When an Alarm is sent from the Zone Based Messages feature in the Mobilaris Situational Awareness application, the alarm is triggered in the tag. The alarm signal is the vibration motor and buzzer running in a periodic sequence and a white/blue LED sequence. By pressing the button, the tag will stop the alarm signal.

Initial Deployment
The default configuration after manufacturing makes the tag connecting to the Network name (SSID) “Epiroc-tag-wifi” with Password “Error-Grumbling9-Chevy”. When successfully connecting to mobile Hotspot running Mobilaris TagConfig, the tag connects to the server in the TagConfig application and downloads initial configuration and certificate needed to connect to the onsite SSID and cluster.

Figure 1 – Deployment procedure overview

Deployment procedure
This section describes how to deploy Mobilaris Companion Wifi tags using the Mobilaris TagConfig application running on an Android device.

Prerequisite

Android device with Mobilaris TagConfig installed and possibility to enable mobile Hotspot
Parameters for SSID, Password for SSID, domain name and certificate to access the cluster hosting the Mobilaris Mining Intelligence™ system
Charged Companion Wifi tag Connected to a charger (USB or charging panel)
Default tag configuration (profile) added in Mobilaris Mining Intelligence™ Admin page, see section 3.1.2.

Procedure
Go to Mobilaris Mining Intelligence™ Admin page. Under Positioning Devices -> Wifi Tags -> Profiles, create a new profile by pressing New (1) or edit an existing profile by pressing (2).
Update parameters under tabs “General” and “Companion Wifi”, figure 3. Select a default profile that tags connecting to Mobilaris Mining Intelligence™ will get, press the arrow besides the Default profile (3) and select the profile you want as default.

Figure 4 – Mobilaris TagConfig Startup view
Fill fields with requested parameters and add certificate. Note: “Cluster Domain Name” should be domain name without a prefix like domain- name.com.
Press “Start”. If Hotspot is not enabled, you will be asked to enable the Hotspot as shown in figure 5.

Figure 5 – Mobilaris TagConfig Enable Hotspot View
Enable Hotspot on your mobile device with credentials:
Hotspot Name (SSID): Epiroc-tag-wifi
Password (SSID Key): Error-Grumbling9-Chevy

Figure 6 – Mobile device Hotspot settings
Return to TagConfig and you will now see the deployment view, figure 7.

Figure 7 – Mobilaris TagConfig Deployment view
If the tag is new from factory the tag will automatically connect to the Hotspot if the tag is charged and connected to a charger. If the tag is being redeployed in a new environment the tag needs to be reset, see section 3.2. The tag will vibrate when successfully reset and after a while connect to the Hotspot. Once the tag is connected to the Hotspot it will start downloading initial configuration (profile) and certificate. During this process, the tags MAC-address is shown in the application as shown in figure 8.

Figure 8 – Mobilaris TagConfig connected tag view
When tag is done with the download, the MAC-address turns green, figure 9. Tag will now disconnect form the hotspot and connect to the onsite network (SSID) and cluster to download the profile that’s been prepared earlier in the Mobilaris Mining Intelligence™ Admin page. The tag will now be visible in Mobilaris Mining Intelligence™.
