LK-GPS - LK300 Protocol

This page covers the public protocol context for using the LK-GPS LK300 tracker with Plaspy. It summarizes how the device reports location and basic telemetry into Plaspy and what to expect from the tracker reporting behavior in general, without exposing private implementation or firmware internals.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when devices report to the Plaspy endpoint. Plaspy's public endpoint is d.plaspy.com (54.85.159.138) on port 8888. The device may be configured using UDP or TCP on port 8888. All devices in Plaspy use the same port, and Plaspy automatically detects the tracker protocol. Exact protocol behavior can vary depending on firmware version, hardware revision, and manufacturer implementation, so verify details with LK GPS documentation when needed.

Protocol Overview​

The protocol used by the LK300 enables the device to deliver location, movement and status information from the field to Plaspy so the data can be displayed, archived and used for alerts. The public view of this protocol focuses on the observable communication role rather than internal frame formats or proprietary parser rules.

  • Provides device identification and session reporting so Plaspy can associate messages with the correct asset.
  • Transports GPS position, movement or vibration events, and basic telemetry that Plaspy converts into usable map positions and alerts.
  • Supports remote configuration triggers such as SMS parameter setting in addition to server reporting for configuration flexibility.
  • Uses standard IP transport over the cellular network to reach the centralized Plaspy endpoint for ingestion and processing.
  • Enables tamper and battery status reporting that Plaspy uses for notifications and operational monitoring.

How Plaspy Detects the Protocol​

Plaspy listens on a single, shared endpoint and port for incoming device reports and detects the tracker protocol automatically so users normally do not need to select a protocol manually. Detection is driven by the characteristics of incoming connections and reported fields rather than requiring user configuration.

  • Devices point to the same Plaspy endpoint so incoming traffic is routed to Plaspy parsers for automatic identification.
  • Plaspy receives data on d.plaspy.com or directly to 54.85.159.138 and ingests reports on port 8888.
  • Because Plaspy uses the same port for all supported trackers, a properly configured device typically appears in Plaspy without manual protocol selection.
  • The platform accepts both UDP and TCP reporting depending on the device configuration and network conditions.
  • If a device is not appearing, verifying the reporting address and transport (UDP or TCP) is a practical first troubleshooting step.

Transport and Connection Context​

The LK300 communicates over the cellular network to reach Plaspy. From a connection point of view, the focus is on reliably delivering messages to the Plaspy endpoint; implementation specifics like frame layout are handled by the device and Plaspy back end.

  • The device may be configured using UDP or TCP on port 8888 depending on device support and installer preference.
  • Devices can be set to report to d.plaspy.com or directly to 54.85.159.138; both targets reach Plaspy on port 8888.
  • All Plaspy supported devices use port 8888 for server reporting, simplifying network and firewall configuration.
  • Cellular connectivity and message retries at the device level affect delivery reliability and timeliness seen in Plaspy.
  • SMS-based parameter setting is often supported for remote configuration when direct IP connectivity is unavailable.

Protocol Compatibility Notes​

  • Firmware versions can change message behavior and available telemetry fields; always check the device firmware release notes for protocol changes.
  • Hardware revisions or regional variants may alter supported bands or available features that affect reporting frequency or telemetry.
  • Some LK300 units support SMS configuration in addition to server reporting; that can be useful when IP connectivity is intermittent.
  • Choosing UDP versus TCP affects delivery guarantees and should match the device configuration used during installation.
  • Confirm the reporting address is set to d.plaspy.com or 54.85.159.138 and the transport set to port 8888 for Plaspy ingestion.
  • Validate any changes to reporting settings against LK GPS documentation to avoid configuration mismatches.

Why Protocol Understanding Matters​

Having a practical understanding of how the LK300 communicates helps installers and operators set up devices correctly, troubleshoot connectivity, and ensure consistent visibility in Plaspy.

  • Ensures the device is pointed to the correct Plaspy endpoint so live positions appear without delay.
  • Helps determine whether to configure UDP or TCP for the expected network conditions and reliability needs.
  • Clarifies whether SMS-based configuration is needed when IP reporting cannot be established.
  • Aids troubleshooting by narrowing down whether issues are network, device configuration, or firmware related.
  • Supports planning for fleet deployments by anticipating differences across firmware or hardware revisions.

Why Use Plaspy with This Protocol​

Using the LK300 with Plaspy gives fleet operators and vehicle owners a straightforward way to bring discreet GPS tracking, tamper detection, and basic telemetry into a centralized monitoring workflow. The combination is suitable for motorcycles, cars, trucks and remote equipment where small form factor, vibration wake-up and reliable cellular reporting are priorities.
