Device Data & Acronyms

OvApp groups device telemetry and configuration into five sections:

  • att – Attributes
  • cmd – Commands
  • sts – Status
  • dta – Data
  • dia – Diagnostics

This page explains the meaning of the acronyms used in each section.

att – Attributes

Static or semi-static identifiers and firmware info.

  • opid – OEM Device ID
    Factory-set unique identifier for the physical device.

  • ppid – PAYG Device ID
    Device ID used by the PAYG system. Factory set, but field overrides may be possible.

  • flid – Fleet ID
    Identifier for the fleet or group the device belongs to. Factory set with optional field override.

  • ccid – Cellular SIM Card ID (ICCID)
    Unique identifier of the SIM card used for cellular connectivity.

  • frmv – Firmware Version
    Current firmware version running on the device.

cmd – Commands

Configuration parameters and last command/control values.

  • pubk – Public Key / Last Code
    Stores the current public key or the last accepted PAYG code.

  • gstw – GPRS Sleep Time Window (minutes)
    Controls how long the device remains in low-power/sleep mode between GPRS sessions.

  • gctw – GPRS Connect Time Window (minutes)
    Defines the length of a GPRS connection window when the device attempts to connect.

  • napn – GPRS Carrier APN Name
    The APN used by the device to connect to the cellular network.

  • swch – Generic Device Switch
    Logical switch for turning certain features or outputs on/off.

  • read – Last Read Request
    Records the last read request for any GATT data, e.g. read = [opid|...|].

  • rptm – Report Mode
    Sets how data is reported:
    0 = Auto-Periodic
    1 = Request-Response
    2 = Change-Notification
    (Values 3, 4 reserved or deployment-specific.)

  • raml – Reserved AML
    Reserved list/field; specific meaning depends on firmware.

  • hbfq – Heart Beat Interval (minutes)
    Interval at which the device sends heartbeat/status messages.

sts – Status

Current state, PAYG info, and basic GPS/network metrics.

  • sstc – System Status Code
    Encodes the current high-level system state.

  • crtm – Created Time
    Timestamp when this record/status snapshot was created.

  • udtm – Updated Time
    Timestamp for the last update to this status.

  • time – Device Internal Time
    Device’s internal clock at the last communication.

  • plat – GPS Latitude

  • plon – GPS Longitude

  • gpss – GPS Signal Strength (dB)

  • gpfc – GPRS Connect Failure Counts
    Number of recent failed attempts to connect via GPRS.

  • rcrd – Remaining Credit Days
    PAYG remaining days.

  • trhd – Total Running History Days
    Total days the device has been operational (historical).

  • tpgd – PAYG Running Days
    Total days under PAYG mode.

  • pgst – PAYG State
    PAYG or FREE, indicating whether PAYG restrictions apply.

  • tkre – Token Response
    Indicates token status from the device’s view: NEW, REPEAT, or ERROR.

  • ocst – Device Output State
    Current state of device outputs (on/off, limited, etc.).
