Autoseeker - AT-5 Protocol

This page covers the public protocol context for using the Autoseeker AT-5 tracker with Plaspy. It explains, at a high level, how the device reports location and events to Plaspy and what to consider when configuring the tracker for cloud reporting. The AT-5 is a magnetic 4G asset tracker with multiple positioning modes including GPS and Beidou plus WiFi and LBS assistance, a high capacity battery, and a set of alarms that generate reportable events.

Plaspy uses shared connection settings for supported devices and automatically detects the tracker protocol when a device reports to the Plaspy endpoint. The Autoseeker AT-5 behavior can vary by firmware version, hardware revision, and manufacturer implementation, so while Plaspy will accept connections using the same server and port, exact message timing and content may differ between devices and firmware builds.

Protocol Overview​

The communication protocol for the AT-5 defines how the tracker sends position samples, status updates, and alarm events to a remote server and how remote commands or acknowledgements are handled where supported. For integration with Plaspy, the public protocol context is primarily about addressing and transport rather than internal packet formats.

  • Allows the AT-5 to report periodic location fixes and event driven updates such as SOS, vibration, or low battery.
  • Enables the tracker to include identifying information so Plaspy can associate incoming reports with the correct device instance.
  • Carries status and sensor data that Plaspy converts into usable telemetry, alerts, and history for monitoring.
  • Supports multiple positioning methods reported by the device so Plaspy can display the most appropriate fix type.
  • Drives alarm and movement notifications that are important for real time monitoring and historical analysis.

How Plaspy Detects the Protocol​

Plaspy detects device protocols automatically once the tracker is configured to report to the Plaspy network endpoint. In most common setups the user does not need to choose a protocol inside Plaspy as long as the device is set to report to Plaspy’s server and port.

  • Devices should be configured to report to Plaspy server domain d.plaspy.com or to the server IP 54.85.159.138.
  • Plaspy listens on port 8888 and all supported devices use the same port for reporting.
  • The AT-5 may be set to use either UDP or TCP transport to reach Plaspy on port 8888 depending on device configuration.
  • Once a device begins reporting to the Plaspy endpoint, the platform will associate incoming data with the appropriate device without requiring a manual protocol selection.
  • Because manufacturers may vary incremental message content, Plaspy’s detection focuses on the addressing and session behavior rather than exposing device internals.

Transport and Connection Context​

Connection context describes how the AT-5 reaches the Plaspy network and which transport options are commonly used. The AT-5 supports cellular reporting and can be configured to target a network host or IP address and a transport protocol.

  • The device may be configured to use UDP or TCP on port 8888 to send reports to Plaspy.
  • Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138 for direct addressing.
  • All devices in Plaspy use the same port and that port is 8888 for incoming tracker data.
  • Choice of UDP versus TCP can affect delivery behavior and should be chosen based on device firmware capabilities and network conditions.
  • Ensure APN and SIM settings on the AT-5 are correct so the device can reach d.plaspy.com or 54.85.159.138 over the cellular network.

Protocol Compatibility Notes​

  • Firmware revisions can change how frequently the AT-5 reports or which fields are included in reports; verify firmware notes when troubleshooting.
  • Hardware revisions and optional features such as WiFi assisted positioning or added sensors can alter available telemetry.
  • Manufacturer-side settings may present protocol variations across regions or factory configurations; check device configuration menus.
  • Transport selection between UDP and TCP may be limited by the device firmware and by mobile network behavior.
  • Always validate compatibility by testing a device against the Plaspy endpoint in a controlled environment before full deployment.
  • Confirm that the device is configured to use the Plaspy server domain or IP and the correct port to avoid connectivity issues.

Why Protocol Understanding Matters​

Understanding how the AT-5 communicates helps ensure a smooth integration, reliable tracking, and efficient troubleshooting when devices are deployed at scale. Knowing the transport and addressing expectations reduces setup time and improves incident response.

  • Helps confirm the device is pointing to d.plaspy.com or 54.85.159.138 and using port 8888 as required by Plaspy.
  • Makes it easier to interpret reported events such as SOS, overspeed, or tamper alerts in the correct context.
  • Enables faster diagnosis of connectivity issues by checking UDP versus TCP selection and cellular reachability.
  • Supports planning for firmware updates or hardware changes that could alter reporting behavior.
  • Reduces time to deploy fleets by ensuring device settings match Plaspy’s shared connection requirements.

Why Use Plaspy with This Protocol​

Using the Autoseeker AT-5 with Plaspy gives organizations a practical path to capture location, status, and alarm events from a compact magnetic asset tracker. Plaspy’s platform accepts reports on a single shared port and automatically detects reported device protocols so teams can focus on operations rather than low level protocol configuration.
