Assets¶

Assets is a diagnostic and inspection tool found under BLE Devices. It is designed for technical staff or distributors who need to see everything about a device at a low level — identity, configuration, status, battery data, diagnostics, and remote monitoring.

Scanning & Connection¶

Assets scan list

When you open the page, your phone immediately scans for nearby OVES devices via Bluetooth. Discovered devices are listed with:

Device name
Product image
Signal strength (RSSI)
MAC address

Connecting to a Device¶

You can connect in three ways:

Method	Description
Tap	Tap a device in the list to connect
Search	Search by device name to filter the list
QR Scan	Scan the device's QR code to connect directly

Once connected, the app reads the device's data and takes you to the detailed device view.

Detailed Device View¶

The top of the screen displays:

Device ID (OPID) — the unique operational identifier
Device image
MAC address

Below this is a tabbed interface with six service sections.

Service Tabs¶

ATT — Attribute (Device Identity)¶

ATT tab

The ATT tab displays the device's identity information:

Serial numbers
Hardware/firmware version
Device model and type
Other identification attributes

You can read individual values from the device and copy them to clipboard.

CMD — Command (Write Operations)¶

CMD tab

The CMD tab exposes command characteristics that you can both read and write:

Action	Description
Read	Read the current value of a command characteristic
Write	Send a value to the device (e.g. activation tokens, APN settings, configuration changes)
Copy	Copy the current value to clipboard

Value Persistence

Written values persist locally, so you can always see what you last sent to the device — even after navigating away and returning.

Common write operations include:

Entering activation tokens to unlock or extend service
Changing APN settings for cellular connectivity
Updating configuration parameters

STS — Status¶

STS tab

The STS tab shows the device's current operational status:

Days remaining — how many days of service are left
Activation state
Other status indicators

You can read values and copy them to clipboard.

DTA — Data (Battery)¶

DTA tab

The DTA tab provides battery-level data:

Field	Description
Voltage	Current battery voltage
Capacity	Total battery capacity
Energy	Energy stored in the battery (kWh)
Other battery metrics	Varies by device

You can read values and copy them to clipboard.

DIA — Diagnostics¶

DIA tab

The DIA tab surfaces deep diagnostic information:

Individual cell voltages — voltage of each cell in the battery pack
Cell temperatures — temperature readings per cell or zone
Other diagnostic parameters

This data is useful for identifying failing cells, thermal issues, or imbalanced packs.

You can read values and copy them to clipboard.

HB — Heartbeat (Remote Monitoring)¶

HB tab

The HB tab collects data from all services (ATT, CMD, STS, DTA, DIA) and sends it to the server via MQTT for remote monitoring.

Action	Description
Trigger heartbeat	Collects a snapshot of all service data and publishes it to the backend
MQTT publish	The data is sent as an MQTT message for centralized tracking

This allows the backend to track which devices have been inspected and their current state — without needing physical access.

Automatic MQTT Publishing¶

Beyond the HB tab, the page also automatically publishes device data to MQTT whenever a service read completes. This means every time you read a value from any tab, the backend is updated — enabling passive monitoring as part of routine inspections.

Summary¶

Tab	Purpose	Read	Write	Copy	MQTT
ATT	Device identity (serial, model, firmware)	Yes	No	Yes	Auto
CMD	Commands (tokens, APN, config)	Yes	Yes	Yes	Auto
STS	Status (days remaining, activation)	Yes	No	Yes	Auto
DTA	Battery data (voltage, capacity, energy)	Yes	No	Yes	Auto
DIA	Diagnostics (cell voltages, temperatures)	Yes	No	Yes	Auto
HB	Heartbeat (all-service snapshot to MQTT)	Yes	No	No	Manual trigger
