TK-Star - LK200B Protocol

This page describes the public protocol context for using the TK-Star LK200B GPS vehicle tracker with Plaspy. It focuses on how the device commonly communicates with a backend service, what to expect from a connection perspective, and how Plaspy interprets incoming data from compatible trackers. The information here is intentionally high level and intended to help with integration and troubleshooting rather than to document proprietary or firmware specific details.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation. Use the guidance below to understand connection context, common compatibility considerations, and practical next steps when configuring LK200B devices to report to Plaspy.

Protocol Overview​

The tracker communication protocol is the public method the LK200B uses to send location and status information to a server. In practical terms, the protocol defines how the device reports its identity, position, motion events, and basic telemetry so a platform like Plaspy can present usable location, alerts, and history data to users.

  • Enables the device to report real time GPS position and movement updates to a remote server
  • Carries identification and basic device metadata so the server can associate data with the correct asset
  • Transmits event notifications such as geofence, overspeed, and movement alerts that Plaspy can surface to users
  • Provides periodic updates for history tracing and interval based auto tracking for route reconstruction
  • Allows the device to send status indicators such as battery level and signal quality which aid monitoring

How Plaspy Detects the Protocol​

Plaspy receives data from many different tracker models and automatically determines which public protocol a reporting device is using. In most cases a properly configured LK200B will begin sending reports to the Plaspy endpoint and the platform will detect the format and start processing data without requiring manual protocol selection.

  • Plaspy server domain for device reporting is d.plaspy.com
  • Plaspy server IP is 54.85.159.138 and the port is 8888
  • Plaspy uses the same port for all supported devices and automatically detects the tracker protocol
  • Devices typically do not require a manual protocol choice inside Plaspy when they are configured to report to the Plaspy endpoint
  • If a device is not detected automatically, checking the device reporting address and transport mode is the first troubleshooting step

Transport and Connection Context​

Transport and connection settings determine how the LK200B reaches the Plaspy endpoint. The LK200B can be configured to report over common transport layers supported by cellular trackers. Understanding these options helps ensure the device can reach Plaspy reliably across different networks and installations.

  • The device may be configured to use UDP or TCP on port 8888 depending on device support and configuration
  • Devices can be set to point to the Plaspy reporting domain d.plaspy.com or directly to the server IP 54.85.159.138
  • Plaspy listens on port 8888 for incoming tracker reports and this is the shared port for all devices in the platform
  • Network elements such as carrier NAT, firewalls, and packet filtering can affect UDP and TCP differently so test both transports if connectivity issues occur
  • Confirm APN and SIM connectivity on the tracker before changing higher level protocol settings

Protocol Compatibility Notes​

  • Firmware revisions can change how features are reported or which events are available; verify firmware notes when behavior differs from expectations
  • Hardware revisions or optional modules may affect available telemetry such as additional sensor inputs or OBD data
  • Some manufacturer configurations allow switching transport or report modes which can impact how Plaspy detects and parses incoming data
  • Always validate device report destination and transport settings against Plaspy server settings to ensure data reaches d.plaspy.com or 54.85.159.138 on port 8888
  • If third party management tools or reseller portals are used to configure the device, confirm those tools do not override server or transport settings
  • When testing, use a staging device or small pilot to confirm behavior before broad deployment

Why Protocol Understanding Matters​

A practical understanding of the LK200B reporting protocol helps ensure reliable setup, faster troubleshooting, and consistent operational monitoring in Plaspy. Knowing the connection expectations and common compatibility variables reduces downtime and improves the accuracy of location and event data collected from the tracker.

  • Speeds up initial commissioning by ensuring the correct server address and transport are configured
  • Simplifies troubleshooting when devices fail to appear in Plaspy by narrowing focus to network, transport, or firmware causes
  • Helps predict how firmware updates may change available events or data fields presented in Plaspy
  • Assists in planning for network conditions where TCP or UDP may be preferable
  • Improves confidence in long term fleet management by clarifying how often position and status updates are expected

Why Use Plaspy with This Protocol​

Using the TK-Star LK200B with Plaspy provides organizations with a practical way to collect vehicle location, alerts, and history for visibility and operational oversight. Plaspy’s automatic protocol detection and shared connection port simplify integration so fleet managers can focus on rules, geofences, and reporting rather than low level parser configuration.
