QuecLink - GV310LAU Protocol

This page describes the public protocol context for using the QuecLink GV310LAU tracker with Plaspy. It focuses on how the device communicates with Plaspy, what to expect from common connection settings, and how telemetry and event data such as GNSS position, CAN bus captures, and BLE sensor readings are delivered to the platform.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device reports to the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so this page provides general guidance rather than exhaustive, firmware specific details.

Protocol Overview​

The GV310LAU uses standard telematics reporting methods to send location, vehicle telemetry, and alarm events to a backend server. The communication protocol governs how the tracker identifies itself, how telemetry is packaged for reliable delivery, and how alarms and remote control commands are represented so Plaspy can ingest and act on them.

  • Enables reliable delivery of GNSS position and multi sensor telemetry including CAN, analog inputs, and BLE sensor data.
  • Carries device identity and status information so Plaspy can associate incoming messages with the correct vehicle and configuration.
  • Communicates alarms and event signals such as crash, tow, ignition, and geo fence triggers for automated workflows.
  • Supports telemetry needed for dashboards, route replay, diagnostics, and scheduled reports within Plaspy.
  • Provides the channel for remote actions when supported by the device such as digital output control for immobilization or accessory control.

How Plaspy Detects the Protocol​

Plaspy collects device traffic at a single shared endpoint and uses that incoming connection to identify the tracker protocol and parse usable telemetry. In most deployments you configure the GV310LAU to report to the Plaspy endpoint and Plaspy will automatically detect and handle the device messages without manual protocol selection.

  • Devices should be pointed at the Plaspy server domain d.plaspy.com or the server IP 54.85.159.138.
  • Plaspy listens on the shared port 8888 for device connections and ingestion across supported devices.
  • The GV310LAU may be configured to use UDP or TCP on port 8888 when reporting to Plaspy.
  • Because Plaspy uses a single port for all supported devices, users typically do not need to choose a protocol inside Plaspy if the device is configured correctly.
  • Plaspy’s automatic detection reduces setup steps but correct device reporting settings and firmware behavior remain important for reliable operation.

Transport and Connection Context​

Connection context covers how the tracker sends its messages to Plaspy and which transport layer options are available. For the GV310LAU, cellular connectivity is the primary transport and protocol selection at the device determines whether messages use UDP or TCP when delivered to Plaspy.

  • The GV310LAU supports LTE Cat 4 connectivity with fallback to 3G and 2G for broad coverage and continuous reporting.
  • Device reporting may be configured to use either UDP or TCP on port 8888 depending on the device configuration and network environment.
  • Devices can be addressed to d.plaspy.com or the numeric server IP 54.85.159.138 for direct reporting to Plaspy.
  • Plaspy’s single port approach means all devices use the same port 8888 for ingestion, simplifying firewall and network configuration.
  • Some deployments may also use SMS or alternative fallbacks for legacy scenarios, but TCP or UDP to the Plaspy endpoint is the primary real time path.

Protocol Compatibility Notes​

  • Firmware variations can change available features and exact message behavior. Verify the device firmware version when troubleshooting.
  • Hardware revisions and regional variants may modify cellular band support or available I/O features that affect telemetry content.
  • Transport selection (UDP versus TCP) can affect delivery characteristics under different network conditions; choose the setting that matches your reliability and latency needs.
  • Manufacturer configuration parameters control which sensors and CAN frames are reported. Confirm device-side configuration matches the telemetry you expect in Plaspy.
  • Test a device in a controlled environment before deploying at scale to validate event mapping, alarms, and remote control behavior.
  • Always consult official QuecLink guidance for variant specific details before performing production changes.

Why Protocol Understanding Matters​

Understanding the communication protocol used by the GV310LAU helps ensure accurate setup, faster troubleshooting, and reliable long term operation when integrated with Plaspy. It clarifies what data is available, how events are reported, and what network settings must be in place.

  • Speeds initial provisioning by ensuring the device is pointed to the correct Plaspy endpoint and port.
  • Helps map device alarms and inputs to Plaspy events for accurate alerting and automation.
  • Aids troubleshooting by narrowing whether issues are on the cellular transport, device configuration, or platform parsing side.
  • Informs decisions about transport selection and retry behavior to match coverage and reliability needs.
  • Supports lifecycle maintenance planning such as firmware updates and regression testing for critical fleet workflows.

Why Use Plaspy with This Protocol​

Using the QuecLink GV310LAU with Plaspy gives fleet operators and integrators a practical path to high-resolution GNSS tracking, vehicle diagnostics, and sensor-rich telemetry. The device’s rugged design, CAN capture, BLE sensor support, and configurable I/O combine with Plaspy’s ingestion to provide actionable location and event data for operations, safety, and anti-theft workflows.
