Xexun - TK-201-2 Protocol

This page describes the public protocol context for using the Xexun TK-201-2 tracker with Plaspy. It focuses on how the device communicates in broad terms, what connection settings are used to reach Plaspy, and the practical considerations you should know when integrating a TK-201-2 unit for pet tracking or broader safety and monitoring use cases.

The TK-201-2 is a compact pet tracker that also sees use for children, elderly care, worker safety, and other discreet tracking scenarios. 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. Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138. The port is 8888 and 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.

Protocol Overview​

The communication protocol for the TK-201-2 establishes how the tracker reports identification, position, alerts, and status to a backend service such as Plaspy. The protocol ensures that location samples, movement and geofence events, battery state, and other tracked signals can be translated into usable telemetry and alerts by the platform.

  • Enables the device to identify itself and send regular position and status reports to a server
  • Carries alert and status messages such as movement alert, overspeed alert, and low battery alert
  • Supports configurable reporting modes like track by time interval and track by distance interval
  • Allows geo-fence events and history trace requests to be communicated to the platform
  • Provides the transportable payload that Plaspy receives and maps into device telemetry and alerts

How Plaspy Detects the Protocol​

Plaspy receives incoming connections on a single shared endpoint and automatically determines the appropriate tracker protocol when a device reports to that endpoint. In most cases you do not need to pick the protocol manually inside Plaspy if your TK-201-2 is correctly configured to report to the Plaspy server.

  • Plaspy server domain is d.plaspy.com which resolves to the Plaspy ingestion endpoint
  • Plaspy server IP is 54.85.159.138 which can be used instead of a domain name if needed
  • The port is 8888 and Plaspy uses the same port for all supported devices
  • Plaspy automatically detects the tracker protocol once the device begins reporting
  • Users typically only need to point the tracker to the Plaspy endpoint and choose UDP or TCP on port 8888 as supported

Transport and Connection Context​

Transport choices determine how the TK-201-2 sends its protocol frames to Plaspy. Devices may be configurable for either UDP or TCP depending on firmware features and local network conditions. Connection stability, firewall rules, and cellular behavior can affect which transport is preferable.

  • The device may be configured using UDP or TCP on port 8888 depending on device support and configuration
  • Devices may point to d.plaspy.com or 54.85.159.138 as the destination for reporting
  • All devices in Plaspy use the same port which simplifies server configuration and device onboarding
  • UDP is commonly used for low overhead reporting while TCP may be selected for guaranteed delivery in some setups
  • Ensure your network or carrier does not block port 8888 for outbound connections from the tracker

Protocol Compatibility Notes​

  • The TK-201-2 is compatible with Plaspy when the device is configured to report to the Plaspy endpoint and port
  • Firmware versions can change reporting behavior or available features; verify firmware specifics when troubleshooting
  • Hardware revisions and regional variants may alter default transport or message content
  • Manufacturer settings on the device determine whether it reports over UDP or TCP and which fields are included
  • Always validate that the device is pointing to d.plaspy.com or 54.85.159.138 on port 8888 when confirming connectivity
  • Review the device configuration after a firmware update to confirm continued compatibility

Why Protocol Understanding Matters​

Having a clear, practical understanding of the TK-201-2 communication protocol helps ensure reliable operation, faster troubleshooting, and predictable behavior in production deployments. Knowing how the device reports and what transport it uses reduces setup time and improves operational confidence.

  • Helps verify that the tracker is reaching Plaspy and being interpreted correctly
  • Makes it easier to diagnose why location updates or alerts are missing
  • Guides appropriate transport selection for the network environment
  • Aids in planning for battery life by understanding reporting intervals and modes
  • Supports smoother firmware upgrade planning and testing for continued compatibility

Why Use Plaspy with This Protocol​

Using the Xexun TK-201-2 with Plaspy gives organizations and owners a practical way to convert device reports into location history, live tracking, and alerting. Plaspy’s shared endpoint model and automatic protocol detection simplify bringing devices online so you can focus on operational monitoring rather than manual parser selection.
