STL - STL060 Protocol

This page covers the public protocol context for using the STL STL060 GPS tracker with Plaspy. It explains, at a high level, how the device reports location and status so that Plaspy can receive and process tracking data. The STL060 is designed to determine precise coordinates from GPS satellites, cache positions when GPRS is unavailable, and respond to SMS requests for location, all of which affect how the tracker communicates with a server such as Plaspy.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device is configured to report to the Plaspy endpoint. Exact protocol behavior for the STL060 can vary with firmware version, hardware revision, and manufacturer implementation, so the details described here are intended as public, high level guidance rather than a firmware specific manual.

Protocol Overview​

The protocol for the STL060 defines how the tracker encodes and sends position, time, and status information to a remote server and how it receives certain configuration or command requests. In practice, this protocol enables the tracker to identify itself to Plaspy, deliver usable telemetry, and support remote management flows such as configuration updates or on demand location requests.

  • Enables the tracker to report GPS coordinates and basic status to a remote server for processing.
  • Carries identity information so Plaspy can associate incoming messages with a specific STL060 device.
  • Allows position data saved during GPRS outages to be uploaded when connectivity returns.
  • Supports SMS-based queries for on demand location reports when SMS is used alongside data reporting.
  • Provides the transport-neutral messages that Plaspy receives and maps to device records and events.

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a shared endpoint and automatically determines the tracker protocol used by each device. When an STL060 is configured to send data to Plaspy, the platform will match incoming messages to the appropriate device record without requiring the user to select a protocol manually in most cases. Automatic detection simplifies setup and reduces configuration errors.

  • Plaspy listens on a single public endpoint for device reports and uses that endpoint to receive messages from many tracker models.
  • All devices reporting to Plaspy use the same port, so STL060 messages arrive on the same service port as other supported devices.
  • Users normally point the tracker to the Plaspy endpoint and do not need to choose a parser in the Plaspy interface if the device is sending data correctly.
  • Automatic detection covers common firmware behaviors, but unusual or heavily customized firmware may require additional validation.
  • If a device is not recognized automatically, checking device settings and manufacturer documentation is recommended.

Transport and Connection Context​

The STL060 can be configured to use UDP or TCP depending on device support and network conditions. For Plaspy, the public server address and port are the canonical targets for tracker reports, and devices may be configured to point to the domain or the server IP directly.

  • Plaspy server domain for device reporting is d.plaspy.com.
  • The Plaspy server public IP is 54.85.159.138.
  • The service port used for all devices is 8888 and the tracker may use either UDP or TCP on that port depending on device configuration.
  • Devices that support both UDP and TCP can be set to the transport best suited to the network and firmware behavior.
  • Ensure the tracker is configured to report to the Plaspy domain or IP and to use port 8888 so the platform can receive and process data.

Protocol Compatibility Notes​

  • Firmware variations can change message timing, available fields, or how certain events are encoded; confirm firmware-specific behavior before relying on a particular message pattern.
  • Hardware revisions between production runs may include different GNSS modules or cellular modems that affect signal acquisition and reporting behavior.
  • Manufacturer-side configuration options, such as SMS fallback or storage behavior during no GPRS, influence when and how data reaches Plaspy.
  • Transport choice matters; if you configure the STL060 for UDP but the network blocks UDP, reports will not reach Plaspy unless switched to TCP.
  • Device identifiers must be correctly set on the tracker so Plaspy can associate incoming messages with the correct asset.
  • Always validate compatibility against the manufacturer documentation for your device serial and firmware level.

Why Protocol Understanding Matters​

Understanding how the STL060 communicates with Plaspy helps ensure a successful setup, reliable tracking, and faster troubleshooting when issues arise. Familiarity with the communication context reduces guesswork and helps teams make informed configuration choices.

  • Helps verify the tracker is pointed to the correct Plaspy endpoint and port so messages arrive reliably.
  • Guides decisions about transport selection between UDP and TCP based on network and firmware behavior.
  • Aids troubleshooting when position uploads are delayed, missing, or inconsistent with expected intervals.
  • Ensures correct mapping of device identity so Plaspy records and displays data for the intended asset.
  • Supports planning for firmware updates, device replacements, or changes in reporting settings without losing continuity.

Why Use Plaspy with This Protocol​

Using the STL060 with Plaspy gives organizations a straightforward way to collect, store, and act on location data from vehicles, people, and assets. Plaspy’s platform receives the tracker reports sent to the shared Plaspy endpoint, associates them with device records, and presents the information for monitoring, alerts, and operational workflows. The STL060’s ability to cache data when GPRS is unavailable and respond to SMS requests complements Plaspy’s data processing and reporting capabilities.
