ATrack - AK1 Protocol

This page provides public protocol context for using the ATrack AK1 tracker with the Plaspy platform. It describes how the device communicates at a high level, how that communication is presented to Plaspy, and what aspects matter for setup and compatibility without exposing firmware internals or private parsing details.

The AK1 is a GPS vehicle tracker that uses GPS and GSM GPRS communication and offers configurable event logic, backup power, and multiple inputs. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact behavior can vary with firmware version, hardware revision, and manufacturer implementation. For connectivity, Plaspy’s public server endpoint is d.plaspy.com and is reachable at 54.85.159.138 on port 8888, and devices may be configured to use either UDP or TCP on port 8888.

Protocol Overview​

The communication protocol on the AK1 governs how location, status, and event information is packaged and sent from the tracker to a remote server. In broad terms the protocol enables identification, reporting, and remote control signals so the tracker and backend platform can exchange meaningful telemetry while the device operates in the field.

  • Carries position updates and basic telemetry such as GPS fixes, time, and status flags to a backend server.
  • Conveys event triggers defined by the AK1 event control engine for remote monitoring and alerts.
  • Provides a method for the tracker to include device identification so the server can associate reports with the correct asset.
  • Enables occasional two way control or configuration workflows when supported by the device and platform.
  • Works over mobile data using the device GSM GPRS connection and the configured APN and transport settings.

How Plaspy Detects the Protocol​

Plaspy receives device reports at a single shared endpoint and automatically determines the tracker protocol so most users do not need to select a protocol manually. When an AK1 is configured to report to Plaspy, the platform maps incoming data to a compatible processing routine and routes telemetry into the Plaspy tracking system.

  • Plaspy’s public server domain is d.plaspy.com and the server IP is 54.85.159.138.
  • Plaspy listens on port 8888 and uses the same port for all supported devices.
  • Devices that are correctly pointed at the Plaspy endpoint will normally be recognized automatically.
  • Manual protocol selection inside Plaspy is rarely required when the device is sending to the shared Plaspy endpoint.
  • Proper identification from the device, such as its IMEI or configured device ID, helps Plaspy associate reports with the correct account.

Transport and Connection Context​

Connection transport determines how messages are delivered from the AK1 to the server but does not by itself change the high level roles of the protocol. The AK1 can be set up to use UDP or TCP depending on firmware capabilities and installation preferences, and either transport can be used to reach the Plaspy service at the configured endpoint.

  • The device may be configured to use UDP or TCP on port 8888 depending on device support and configuration.
  • Devices can point to the domain d.plaspy.com or the numeric host 54.85.159.138 to reach Plaspy.
  • Plaspy uses the same port 8888 for all devices it supports which simplifies deployment and firewall rules.
  • Choose UDP for lower overhead and potentially faster delivery, or TCP for reliable delivery where supported by the tracker and network.
  • Ensure the device APN and GSM registration are working so the tracker has mobile data connectivity to reach the Plaspy endpoint.

Protocol Compatibility Notes​

  • Firmware versions on the AK1 can alter message timing, available fields, or optional features; check the device firmware release notes when troubleshooting.
  • Hardware revisions or accessory options such as external antennas and sensors may add or change the set of reported inputs.
  • Manufacturer configuration menus may offer transport selection or configurable reporting intervals that affect behavior on the server.
  • Always verify that the device is configured to report to d.plaspy.com or 54.85.159.138 on port 8888 and that the chosen transport matches the device setting.
  • Differences in regional GSM behavior or APN setup can impact connectivity and should be validated during installation.
  • Consult official ATrack documentation for firmware specific notes that could impact compatibility with third party platforms.

Why Protocol Understanding Matters​

A practical understanding of the AK1 communication protocol helps with correct installation, efficient troubleshooting, and maintaining reliable telemetry over time. Knowing the general role of the protocol and connection context reduces setup time and helps isolate issues that are transport, configuration, or firmware related.

  • Speeds up initial device provisioning by clarifying required server, transport, and identification settings.
  • Simplifies troubleshooting when devices fail to appear in Plaspy by narrowing the problem to connectivity, transport, or device configuration.
  • Helps you choose appropriate transport and reporting intervals for battery life and bandwidth considerations.
  • Makes it easier to validate that event triggers and input mappings from the AK1 appear as expected on the platform.
  • Reduces guesswork when coordinating with manufacturer support or field technicians during deployments.

Why Use Plaspy with This Protocol​

Using an AK1 with Plaspy provides a practical path to centralize vehicle location, event monitoring, and basic telemetry across a fleet. The AK1’s event control engine, multiple inputs, and power management features pair well with a platform that automatically receives and processes device reports, allowing organizations to focus on operations rather than protocol parsing.
