QuecLink - GV500 Protocol

This page covers the public protocol context for using the QuecLink GV500 tracker with Plaspy. It summarizes how the GV500 reports position, OBDII data, and event alerts to a backend server and explains the key connection settings that Plaspy expects for receiving device reports.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior for the GV500 can vary with firmware version, hardware revision, and manufacturer configuration, so this page focuses on safe public details and the common integration points used with Plaspy.

Protocol Overview​

The GV500 uses an embedded reporting protocol to deliver GPS positions, OBDII data, motion events, and alerts over GPRS to a remote server. In general terms, the protocol defines how the device identifies itself, how it reports periodic and event driven data, and how it conveys vehicle diagnostics and sensor information to a backend.

  • The protocol carries location fixes, timestamps, and movement state so Plaspy can display positions on maps and calculate routes.
  • Device identity and basic status information allow Plaspy to associate incoming reports with the correct vehicle or asset.
  • Event reports such as geo fence crossing, emergency alerts, and low battery notify the backend of exceptional conditions.
  • OBDII and vehicle diagnostic data reported by the GV500 provide additional telematics fields for fleet analytics.
  • The GV500 implements the embedded @Track reporting set used by QuecLink devices to structure its reports.

How Plaspy Detects the Protocol​

Plaspy receives incoming device traffic on a single shared endpoint and port and performs automatic protocol detection for connected trackers. When the GV500 is configured to report to the Plaspy endpoint, manual protocol selection inside the platform is typically not required.

  • Plaspy server domain for device reporting is d.plaspy.com.
  • Plaspy server IP is 54.85.159.138 and the platform listens on port 8888.
  • Devices may be configured to use either UDP or TCP for transport to the Plaspy endpoint.
  • All devices in Plaspy use the same port, which simplifies device configuration and onboarding.
  • If the GV500 is correctly pointed at the Plaspy endpoint, Plaspy will automatically detect the tracker protocol and begin parsing supported report types.

Transport and Connection Context​

The GV500 communicates over GPRS/GSM networks and can be pointed to a backend server by name or IP. For use with Plaspy, set the device reporting destination to the Plaspy server and choose the transport the device supports.

  • The device may be configured to use UDP or TCP on port 8888 depending on device support and configuration.
  • Devices can be set to report to the domain d.plaspy.com or directly to the IP 54.85.159.138.
  • Plaspy uses the same port 8888 for all supported devices to simplify configuration across a mixed fleet.
  • The GV500 reports over GPRS and relies on the mobile operator data channel to reach the Plaspy endpoint.
  • Transport selection (UDP vs TCP) can affect delivery behavior and should be chosen based on device settings and network conditions.

Protocol Compatibility Notes​

  • Firmware revisions may introduce new report types or change how certain fields are encoded; always check device firmware notes when troubleshooting.
  • Hardware revisions and regional variants can affect available features such as OBDII data coverage or antenna options.
  • Manufacturer settings determine whether the device uses UDP or TCP by default; verify the device configuration before onboarding.
  • The GV500 implements the embedded @Track reporting set, but payload details and available events depend on firmware and setup.
  • Plaspy automatically detects supported protocols, but proper server and transport configuration on the device is required for successful detection.
  • Validate compatibility against QuecLink documentation and release notes for model specific behavior.

Why Protocol Understanding Matters​

Understanding how the GV500 communicates helps reduce setup time, speed troubleshooting, and improve long term reliability when used with Plaspy. Clear knowledge of the expected reports and connection context allows operators to confirm that devices are reaching the platform and that the data being sent is meaningful for operations.

  • Ensures correct server name or IP and transport is configured so reports reach d.plaspy.com on port 8888.
  • Helps distinguish network or SIM issues from protocol or firmware related problems.
  • Makes it easier to interpret event reports such as geo fence alerts, emergency triggers, and low battery notifications.
  • Guides decisions about firmware updates, configuration changes, or hardware swaps when features differ across units.
  • Improves confidence when integrating OBDII and vehicle diagnostic fields into fleet workflows and analytics.

Why Use Plaspy with This Protocol​

Using the QuecLink GV500 with Plaspy provides a practical combination for organizations that need real time vehicle visibility plus optional OBDII based diagnostics. The GV500’s OBDII connectivity, accelerometer based motion detection, and embedded reporting capabilities make it suitable for fleet monitoring, driver behavior analysis, and asset security when paired with a backend that understands its reports.

Plaspy’s shared connection settings and automatic protocol detection reduce configuration overhead during onboarding.
