Uplinks

The Uplinks page provides detailed visibility into all messages sent by devices to the LoRaWAN network.
This view is essential for diagnostics, radio performance analysis, and validating that devices are sending data as expected.

Users can filter uplinks, inspect radio metrics, open individual uplink details, and decode payloads.


Each row in the uplinks table represents a single uplink message.
Columns include:

  • Timestamp – when the uplink was received
  • DevEUI – unique identifier of the sending device
  • Port – LoRaWAN Port value
  • Payload – raw payload bytes (hex-encoded)
  • Best RSSI – strongest received signal strength
  • Best SNR – highest signal-to-noise ratio
  • Uplink counter – frame counter value
  • Spreading Factor – SF used during transmission
  • Confirmed – whether the uplink was confirmed or not

Clicking any uplink row opens the detailed uplink page.


Filter Controls​

At the top of the page, users can apply multiple filters:

Filter by Port​

Filters uplinks by LoRaWAN FPort.
Selected ports appear as removable tags.

Filter by DevEUI​

Filters uplinks by device identifier.
Pressing Enter is required after typing a DevEUI or port value to apply the filter.

Multiple filters may be active simultaneously.


Date Range Selector​

The date range selector allows filtering uplinks by a custom time interval.
Clicking the date field opens:

  • a monthly calendar
  • navigational arrows for switching months
  • Start time and End time pickers

This enables precise filtering down to the minute.


Quick Range Presets​

Preset options allow fast filtering without using the calendar:

  • Today
  • Yesterday
  • Last week
  • Last month
  • Last 3 months

Selecting a preset automatically reloads the uplinks list for the chosen period.


Opening an Uplink Details Page​

Clicking an uplink entry opens a dedicated detail page containing extensive information about that specific uplink.

This view includes:

  • Port
  • Best RSSI
  • Timestamp
  • Confirmed/Not confirmed
  • DevEUI (with link to the device details)
  • Spreading Factor
  • Counters (uplink / downlink)
  • Consumed airtime

A Back to Uplinks button allows returning to the list view.


Uplink Details Page

Summary Section​

The top section of the uplink detail page displays key metadata:

  • Payload (raw hex string)
  • DevEUI (link to the related tracker page)
  • Spreading Factor
  • Consumed airtime
  • Best RSSI
  • Best SNR
  • Uplink counter
  • Downlink counter

Positions​

If location information is available, the Positions section displays:

  • Coordinate source (e.g., LoRa)
  • Latitude and longitude
  • A map showing the resolved position

Maps support zooming, panning, and marker inspection.


Decoder​

The Decoder section shows the payload decoded into structured JSON format.
This section is used for understanding device data, telemetry values, battery status, configuration changes, and more.

An example decoded payload may look like:

{
  "data": {
    "dutycycle": false,
    "configId": 0,
    "configChange": false,
    "lowBattery": false,
    "battery": "3.771v"
  },
  "traceId": "example-trace-id",
  "warnings": null
}
